# SkylandX MetaCam Air 2 RTK Setup: NTRIP in MetaCam Go

Connect a SkylandX MetaCam Air 2 or Air to RTKdata NTRIP in MetaCam Go: mobile data, iPhone Wi-Fi IP, server, port 2101, AUTO mountpoint and the fix check.

This page covers the SkylandX MetaCam Air 2 RTK setup with RTKdata NTRIP corrections for two handheld SLAM scanners: the **MetaCam Air 2** and the first-generation **MetaCam Air**. Both have the RTK module built in. You set them up in the **MetaCam Go** app on iOS or Android, and you georeference the scans in **MetaCam Studio** on Windows. The MetaCam Pro, MetaCam Lite and MetaCam Air 3 are listed in the [model table](#which-metacam-models-can-use-rtkdata-corrections) with what applies to each.

For the MetaCam Go RTK account you turn on **Enable RTK Account** in the **RTK** tab of MetaCam Go and enter your RTKdata NTRIP credentials under **Edit Account**. The phone sits on the scanner's Wi-Fi, and MetaCam Go carries the corrections over the phone's mobile data.

These are the MetaCam Go NTRIP settings for RTKdata. Enter them in MetaCam Go under **Start** > gear icon (**Settings**) > **RTK**: turn on **Enable RTK Account**, then tap **Edit Account**. Select the tab for your region and use the server closest to your work area. All three servers share the same base station network; the difference is routing latency. See [NTRIP Server Settings](/get-started/network.md).

| NMEA GGA                  | No switch in MetaCam Go. Outdoors, wait for **Satellites** and **Single** before you tap **Confirm**.                                                    |

Enter the host name in **Server** first, without `http://` and without a port, because **Port** is a separate field. SkylandX's tutorials show IP addresses in **Server**. If **Station Status** stays **Disconnect** with the host name, especially on an iPhone with the manual Wi-Fi IP from step 1 below, enter the IP fallback of the same region in **Server**. MetaCam Go has no GGA switch: give the scanner a position outdoors before you confirm the account, as described in the steps below.

{% hint style="info" %}
**Port stays `2101`.** The red note **Corresponds to WGS84** below **Port** is fixed app text, not a setting for RTKdata. Do not copy the port from SkylandX's tutorial videos: those ports belong to other correction services. With RTKdata you choose the reference frame with the mountpoint, see [the datum box below](#how-do-you-georeference-a-metacam-scan-in-metacam-studio).
{% endhint %}

## Which MetaCam models can use RTKdata corrections?

For SkylandX MetaCam RTK with RTKdata, the MetaCam Air 2 and the first-generation MetaCam Air can take NTRIP corrections in MetaCam Go, because both have the RTK module built in and MetaCam Go accepts a manually entered NTRIP account; the MetaCam Pro takes an RTK module, but SkylandX shows the RTK steps only on the Air 2 and Air, the MetaCam Lite has no RTK, and the MetaCam Air 3 is not covered yet.

| Model                          | RTK                                                                              | Status of the steps on this page                                                                                                                                                                        |

## What do you need before connecting a MetaCam Air 2 or Air?

To connect a MetaCam Air 2 or Air to RTKdata you need the scanner, a current MetaCam Go app on a phone with mobile data, current scanner firmware, active RTKdata NTRIP credentials and RTKdata coverage at your site, plus MetaCam Studio with its USB dongle for georeferencing.

* **Scanner with RTK.** MetaCam Air 2 or MetaCam Air. RTK is built in, there is nothing to mount.
* **MetaCam Go**, the international app, in a current version: from the App Store on iOS (iOS 15.6 or later), or on Android as the APK from the official download link on the [SkylandX software page](https://skylandx.com/software-platforms/).
* **Phone with a SIM and mobile data.** The phone's Wi-Fi is taken by the scanner, so the corrections come over mobile data, see the next section. Abroad, turn on data roaming.
* **No VPN** on the phone. MetaCam Go warns **Please do not use VPN**.
* **RTKdata account** with active RTK credentials (username starts with `rtk`).
* **Coverage at your site.** Check the [RTKdata coverage map](/get-started/coverage-map.md) before the job.
* **MetaCam Studio** on a PC with Windows 10 or later, 64 bit, with the USB dongle plugged in. SkylandX: "The software requires the dongle to remain connected".

### App and firmware versions

Update the scanner firmware and MetaCam Go in the office before the first field job. After you connect the scanner, MetaCam Go checks whether the firmware is the latest version and offers the update. During the update the app shows **Please do not close the APP or change network status during the upgrade process.**, so do not switch Wi-Fi or change the iPhone IP settings while it runs.

On the MetaCam Air 2, install at least `metacam-runtime_v1.0.6`. SkylandX's release notes for that version list the fix of "a critical issue where the status was delayed by approximately 3 minutes when switching from a fixed solution to no-solution / single-point solution". With older firmware the status could still show **Fixed** for minutes after the fix was lost.

The labels on this page come from the English MetaCam Go interface in SkylandX's tutorials.

Current app version when this page was written: MetaCam Go 2.3.2 on iOS and 2.3.2.1 on Android, MetaCam Studio 1.7.7 (September 2026).

## Where does the MetaCam get internet for RTK corrections?

A MetaCam Air 2 or Air gets its RTKdata corrections through MetaCam Go on your phone: the phone joins the scanner's Wi-Fi `MetaCam-...`, which has no internet access, and MetaCam Go fetches the corrections over the phone's mobile data.

SkylandX's specifications list Wi-Fi 6 and Bluetooth as the connections of the Air 2 and the Pro, and no cellular modem, so the scanner does not go online by itself. Without mobile data MetaCam Go shows **To use RTK, please enable mobile data**.

{% hint style="warning" %}
**If the phone's Wi-Fi is connected to the scanner, the internet has to come from mobile data.** Turn mobile data on before you connect, and data roaming if you use your SIM abroad. A Wi-Fi-only tablet, a phone without a SIM or a phone with mobile data switched off gets no corrections.
{% endhint %}

An iPhone needs one extra setting so that it keeps using mobile data while it is on the scanner Wi-Fi: a manual IP address for that Wi-Fi, see step 1 below. On Android, SkylandX's tutorial shows no extra step. The [CHCNAV RS10 / RS30](/integration-hub/lidar-scanners-and-mobile-mapping/chcnav-rs10-rs30.md) uses the same pattern with its tablet on the scanner Wi-Fi.

## How does the MetaCam Air 2 RTK setup work in the MetaCam Go RTK tab?

To set up MetaCam Air 2 RTK with RTKdata, you connect the phone to the scanner Wi-Fi with mobile data on, tap **Start** in MetaCam Go, open the gear icon (**Settings**) at the top right, select the **RTK** tab, turn on **Enable RTK Account** and enter the RTKdata values under **Edit Account**: **Server** `rtk.rtkdata.com` (North America), `eu.rtkdata.com` (Europe) or `aus.rtkdata.com` (Australia), **Port** `2101`, **Mount Point** `AUTO`, and the username and password from *RTK Credentials* in **Account** and **Password**, then you tap **Confirm**.

{% hint style="warning" %}
**Set up RTK before you start the scan.** MetaCam Studio offers the **RTK** optimizer only for scans that were recorded with RTK on. SkylandX: "RTK, control point, and breakpoint resume settings are only available if enabled during scanning". A scan recorded without RTK can only be georeferenced with ground control points afterwards.
{% endhint %}

{% stepper %}
{% step %}

### Connect the phone to the scanner Wi-Fi

1. Outdoors, power on the scanner. The MetaCam Go manual says: "Press the battery handle button briefly and then press and hold it".
2. In MetaCam Go, tap **Device Connection** or **Connect Device via WIFI**. The app opens the Wi-Fi settings of the phone.
3. Select the scanner Wi-Fi. Its name starts with `MetaCam-`, on the Air 2 `MetaCam-Air2-...`.
4. Set up the network for your phone as shown in the tabs, then return to MetaCam Go.

{% tabs %}
{% tab title="iOS" %}
The iPhone needs a manual IP address on the scanner Wi-Fi, as SkylandX shows in its iOS tutorial:

1. In the iOS settings, open **Wi-Fi** and tap the **(i)** button next to the `MetaCam-...` network.
2. Tap **Configure IP** (some iOS versions show **Configure IPv4**) and select **Manual**.
3. **IP Address:** `10.42.0.100`
4. **Subnet Mask:** `255.255.0.0`
5. **Router:** leave empty.
6. Tap **Save**.

SkylandX: "Then the iPhone can access cellular data while connecting to Wi-Fi". Keep mobile data on.
{% endtab %}

{% tab title="Android" %}
No extra step. Keep mobile data on while the phone is connected to the scanner Wi-Fi.
{% endtab %}
{% endtabs %}
{% endstep %}

{% step %}

### Open the RTK tab

1. In MetaCam Go, tap **Start**.
2. Tap the gear icon at the top right (**Settings**) and select the **RTK** tab.
3. In the **Display** tab next to it, turn on **Operation Reminder**. SkylandX: "You can also use the Operation Reminder feature to get a quick alert if the RTK status changes".
   {% endstep %}

{% step %}

### Turn on Enable RTK Account

1. Turn on **Enable RTK Account**. **Edit Account** and **Test Network** appear.
2. Optional: tap **Test Network** and wait for **OK**. This only checks the phone's internet connection, not the RTKdata server, your credentials or the mountpoint.
3. The **RTK** tab shows **Station Status**, **Longitude**, **Latitude**, **Ellip. Height** and **Satellites**. Outdoors, wait until **Satellites** shows satellites and the RTK status at the top shows **Single** before you continue.
   {% endstep %}

{% step %}

### Enter your RTKdata account in Edit Account

Tap **Edit Account** and fill in the fields:

1. **Account:** your NTRIP username from *RTK Credentials* in your [account dashboard](https://rtkdata.com/my-account/rtk-credentials/). It starts with `rtk` and is not your website login.
2. **Password:** the NTRIP password from *RTK Credentials*, not your website password.
3. **Server:** the host name for your region, `rtk.rtkdata.com` (North America), `eu.rtkdata.com` (Europe) or `aus.rtkdata.com` (Australia), without `http://` and without a port. Use the IP fallback from the region tabs at the top of this page if **Station Status** stays **Disconnect** with the host name.
4. **Port:** `2101`. Keep this port, whatever the red note **Corresponds to WGS84** below the field says.
5. **Mount Point:** type `AUTO` in capital letters, or pick it from the list in the next step. Check that the phone keyboard has not changed the capitals.

{% hint style="info" %}
**AUTO needs your scanner's position.** The caster picks the nearest base station from the position your scanner reports (NMEA GGA). Without a position the login succeeds, but no corrections arrive. See [NTRIP & GGA Essentials](/integration-hub/ntrip-clients-and-field-software/ntrip-and-gga-essentials.md). MetaCam Go has no GGA switch. Give the scanner a position before you confirm the account: stay outdoors and wait until **Satellites** shows satellites and the status shows **Single**.
{% endhint %}

{% hint style="info" %}
Type the username and password instead of pasting them, and check that no field starts or ends with a space. One set of credentials allows one connection at a time, so every scanner or other device that is connected at the same time needs its own data stream. See [Account & Credentials](/get-started/account-and-credentials.md#using-one-subscription-with-several-devices).
{% endhint %}
{% endstep %}

{% step %}

### Optional: pick AUTO from the mountpoint list

1. Tap the icon next to **Mount Point**. The **Mount Point** dialog lists the mountpoints of the server.
2. Tap **Apply** in the row of `AUTO`. The list can show more entries than `AUTO`, `AUTO_ITRF2020`, `AUTO_ITRF2014` and `AUTO_WGS84`: pick `AUTO` unless your project needs one of the global frames.

The RTKdata sourcetable loads without a login (checked on 26 September 2026), so a visible mountpoint list proves neither your credentials nor a running correction stream.
{% endstep %}

{% step %}

### Confirm the account

1. Tap **Confirm**. MetaCam Go shows **RTK Data Request in Progress!**. If it shows **Please enable mobile data!** instead, turn on mobile data and tap **Confirm** again.
2. Tap **Exit** to return.

**Set RTK account successfully!** only means that the scanner has taken over the values. It does not show that RTKdata has accepted your login.
{% endstep %}

{% step %}

### Wait for Fixed, then create the project

1. Stay outdoors under open sky. SkylandX recommends starting "in an open area with more than 30 satellites".
2. Wait until the RTK status at the top shows **Fixed**. SkylandX: "Wait a few seconds for the RTK status to show Fixed". Tap the status and check **Station Status: Connected** and **Differential Age**.
3. If the status stays at **Single** or **Float** for more than a few minutes under open sky, go to the [checklist below](#why-does-metacam-go-connect-but-never-reach-fixed).
4. Only then create the project and start the scan, see the next section.
   {% endstep %}
   {% endstepper %}

### Reuse a saved account

MetaCam Go keeps the accounts you have used. Next time, tap the clock icon (history button), and under **Historical Account** tap **Apply** at the RTKdata account. Remove old entries with **Delete**. Before each scan, check that **Enable RTK Account** is on and the status reaches **Fixed**.

## How do you know the MetaCam has a usable RTK fix?

A MetaCam Air 2 or Air has a usable RTK fix from RTKdata when the RTK status at the top of MetaCam Go shows **Fixed** and the RTK details show **Station Status: Connected** with a **Differential Age** value, which means correction data is arriving.

* The RTK status at the top shows **None**, **Single**, **DGPS**, **PPS**, **Float** or **Fixed**. Only **Fixed** counts for the scan.
* Tap the status to open the details: **Station Status: Connected**, **HRMS**, **VRMS**, **PDOP** and **Differential Age**.
* SkylandX warns of a "false fixed". Check **HRMS**, **VRMS** and **PDOP** as well, and start in an open area with more than 30 satellites.

{% hint style="warning" %}
**Test Network OK is not a fix.** **Test Network** **OK** only checks the phone's internet, and **Set RTK account successfully!** only means that the scanner has taken over the values. Neither one proves a login or a fix. Only **Station Status: Connected**, a **Differential Age** value and **Fixed** count.
{% endhint %}

### Scanning with RTK

* Start the scan only at **Fixed**: tap **Start**, create and name the new project with the red button on the right, tap **Confirm** and keep the scanner still during initialization, as MetaCam Go prompts.
* Start and end the scan outdoors under open sky.
* With **Operation Reminder** on, MetaCam Go shows a pop-up when the RTK status changes during the scan.
* After the scan, check **Fixed Solution Ratio** in the **Job Report**. A low ratio means that parts of the scan were recorded without a fix.

## How do you georeference a MetaCam scan in MetaCam Studio?

You georeference a MetaCam Air 2 or Air scan recorded with RTKdata corrections in MetaCam Studio by ticking **RTK** under **Optimizer** when you create the task. If you need the output in another coordinate system, SkylandX uses **RTK Registration** with a **Target System**; with the `AUTO` mountpoint, choose a projected system of your regional datum and check the result at one known control point.

1. Copy the scan to the PC. MetaCam Air 2: remove the TF card from the scanner and read it with a card reader. MetaCam Pro: SkylandX lists "USB 3.0 Type-C" for data export from its 1 TB built-in SSD.
2. Open MetaCam Studio with the USB dongle plugged in and **Import** the data.
3. Create a **New Task** and tick **RTK** under **Optimizer**. If **RTK** is missing, RTK was not active during the scan.
4. Use MetaCam Studio RTK Registration only if you need another coordinate system for the output: click **RTK Registration**. In the **Transfer Coordinate** dialog, set **Coordinate type** to **Known coordinate system** and enter the projected system of your regional datum by EPSG code in **Target System**, for example 25832 (ETRS89 / UTM zone 32N) or 6346 (NAD83(2011) / UTM zone 17N). For a system without an EPSG code, use **Custom Coordinate System**. Close the dialog with **Confirm**.
5. Run the task. The georeferenced point cloud is in the **geo** folder under **Result**. SkylandX: "Inside the geo folder you'll find the georeferenced point cloud data".
6. Check the result at one known control point.

{% hint style="info" %}
**Use AUTO, choose a target system in the same regional datum, do not add a WGS84-to-national transformation, check one control point.**
{% endhint %}

`AUTO` delivers the corrections in the regional datum for your position, for example NAD83(2011) in the USA, NAD83(CSRS)v7 in Canada, ETRS89 (realization ETRF2000) in Europe and GDA2020 in Australia. For regions without a listed regional datum, `AUTO` falls back to WGS84(G2139) at the mid-year epoch. `AUTO_ITRF2020` and `AUTO_ITRF2014` deliver ITRF at the current epoch, and `AUTO_WGS84` delivers WGS84(G2139) at the mid-year epoch. The full list per country is in [Coordinate Systems & Datums](/get-started/coordinate-systems-and-datums.md).

* **WGS84 labels.** The red note **Corresponds to WGS84** under **Port** does not change the frame: with `AUTO` the corrections arrive in your regional datum. Why scanner software often says WGS84 is explained in [Georeference SLAM Point Clouds with RTK](/integration-hub/lidar-scanners-and-mobile-mapping/georeferencing-slam-point-clouds-with-rtk.md#why-does-my-scanner-software-say-wgs84-when-i-use-auto).
* **Source datum in MetaCam Studio.** SkylandX does not document which source datum MetaCam Studio assumes for the RTK positions. Choose a **Target System** in the same regional datum, do not add a WGS84-to-national datum transformation on top, and check a control point. A consistent offset of 50 cm to 1 m against control is a datum mismatch, not an accuracy problem, see [Why Your Coordinates May Be Offset](/get-started/coordinate-systems-and-datums.md#why-your-coordinates-may-be-offset).
* **Global mountpoints.** Use `AUTO_ITRF2020` or `AUTO_WGS84` only when the deliverable must stay in a global frame. Reaching a national system from those mountpoints needs a real datum transformation in MetaCam Studio. Keep one mountpoint per project.
* **Heights.** Heights are ellipsoidal, as the field **Ellip. Height** in the **RTK** tab shows. For heights above sea level, apply a geoid model: a difference of 10 to 50+ m against benchmarks is the geoid separation. See [Understanding Heights](/get-started/understanding-heights.md).
* **Ground control points.** SkylandX states that in batch mode "control point calibration is not yet supported", so process projects with control points one at a time. Keep the control points in the same frame and height reference as your **Target System**.

### PPK and the MetaCam models

SkylandX lists PPK in the MetaCam Pro specification ("SOTA-SLAM (Support RTK, PPK, GCPs)"). The MetaCam Air 2 specification lists "SOTA-SLAM (Supports RTK, GCPs)" and does not name PPK, so on the Air 2 and Air plan on RTK during the scan or on ground control points. Where PPK is available, it needs base station observation data for the whole scan, usually from a base station you run yourself, and the RTKdata NTRIP stream does not replace those observations. Decide before the scan, see [Is RTK or PPK better for a handheld SLAM scanner?](/integration-hub/lidar-scanners-and-mobile-mapping/georeferencing-slam-point-clouds-with-rtk.md#is-rtk-or-ppk-better-for-a-handheld-slam-scanner).

## Why does MetaCam Go connect but never reach Fixed?

MetaCam Go can accept the account and still get no RTKdata corrections when the phone has no mobile data, the credentials or the mountpoint are wrong, or the scanner has no position yet; check mobile data (and the manual IP on an iPhone), retype the RTK credentials, enter `AUTO` in capitals, wait outdoors for **Single**, and use the regional IP fallback in **Server** last, until **Station Status** shows **Connected** and the status reaches **Fixed**.

A status of **Single** with **Station Status: Disconnect** means that the connection to RTKdata is not up yet:

1. **Phone internet.** Mobile data on, data roaming on abroad, VPN off. On an iPhone, check the manual IP for the scanner Wi-Fi from step 1.
2. **Account and Password.** Retype both from *RTK Credentials*, without spaces and without automatic capitals. The username starts with `rtk`.
3. **Mount Point.** Check that it reads `AUTO` exactly, in capital letters.
4. **Position.** Outdoors, wait until **Satellites** shows satellites and the status shows **Single**. Then turn **Enable RTK Account** off and on and tap **Confirm** again.
5. **IP fallback.** Enter the IP fallback of your region in **Server** (`13.56.117.10` North America, `3.73.41.96` Europe, `54.206.56.130` Australia), keep **Port** `2101` and **Mount Point** `AUTO`, and tap **Confirm**.
6. **Second device.** If another device uses the same credentials at the same time, disconnect it or add a data stream.

## Frequently asked questions

### Does the MetaCam Lite support RTK?

No. The MetaCam Lite has no RTK: its specification lists "SOTA-SLAM (support GCPs)" and no RTK section, and SkylandX notes in the MetaCam Go manual that "Some device models do not support enabling RTK." Georeference Lite scans with ground control points. The RTKdata setup on this page applies to the MetaCam Air 2 and the first-generation MetaCam Air.

### Can I use a third-party NTRIP service like RTKdata in MetaCam Go?

Yes. MetaCam Go takes a manually entered NTRIP account, so the MetaCam Air 2 NTRIP corrections can come from RTKdata: turn on **Enable RTK Account** in the **RTK** tab and enter **Account**, **Password**, **Server**, **Port** and **Mount Point** under **Edit Account**. SkylandX's *RTK Configuration Guide (Android)* shows this step with the caption "Or enter your NTRIP account manually". RTKdata streams RTCM 3.2 with MSM messages, see [Correction format](/integration-hub/ntrip-clients-and-field-software/ntrip-and-gga-essentials.md#correction-format).

### Does MetaCam Go need mobile data on my phone for RTK?

Yes. The phone's Wi-Fi is connected to the scanner Wi-Fi `MetaCam-...`, which has no internet, so MetaCam Go fetches the RTKdata corrections over the phone's mobile data. Without it the app shows **To use RTK, please enable mobile data**. On an iPhone, set **Configure IP** to **Manual** for the `MetaCam-...` Wi-Fi with **IP Address** `10.42.0.100`, **Subnet Mask** `255.255.0.0` and **Router** empty, so that the iPhone keeps using mobile data.

### Which port do I enter when MetaCam Go shows Corresponds to WGS84?

Enter `2101`. The red note **Corresponds to WGS84** below **Port** is fixed app text, not a setting for RTKdata. With RTKdata you choose the reference frame with the mountpoint: `AUTO` delivers your regional datum, and `AUTO_WGS84` delivers WGS84(G2139) at the mid-year epoch.

### Does this guide cover the MetaCam Pro and the MetaCam Air 3?

MetaCam Pro RTK is covered only as a model note, and the MetaCam Air 3 not yet. The Pro takes an RTK module (SkylandX lists "1,160 g (w/o RTK); 1,325 g (w/ RTK)"), which must be mounted before you connect. SkylandX shows the RTK steps on the Air 2 and Air, so check the labels on the Pro against this page. The Air 3, presented on 15 September 2026, is not covered: SkylandX states that "Product configurations, regional availability, and commercial details will be announced separately".

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.rtkdata.com/integration-hub/lidar-scanners-and-mobile-mapping/skylandx-metacam.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question.
