# MicroSurvey FieldGenius

MicroSurvey FieldGenius is a professional survey field software developed by MicroSurvey (a Hexagon company). Available for both Windows and Android, it supports a wide range of GNSS receivers including Trimble, Leica, Topcon, and generic NMEA devices. Its built-in NTRIP client makes it straightforward to connect to RTKdata.com and receive real-time RTK corrections for centimeter-level positioning in the field.

## Requirements

* Windows tablet/laptop or Android device running FieldGenius
* Compatible GNSS receiver (Trimble, Leica, Topcon, or any generic NMEA receiver)
* Internet access on the field device (cellular data, Wi-Fi, or hotspot)
* GNSS antenna with clear sky view (survey pole or tripod recommended)
* Active RTKdata.com account with RTK credentials (username starting with `rtk`)

## Step-by-step setup

{% stepper %}
{% step %}

#### Configure your instrument profile

1. Open FieldGenius and create or open a project.
2. Go to **Survey > Instrument > Select Instrument**.
3. Choose the correct **manufacturer and model** that matches your GNSS receiver hardware.
4. If your receiver is not listed, select **Generic NMEA** as the instrument type.
5. Set the **communication port** (COM port) to match the connection to your receiver — Bluetooth serial port, USB, or internal.
6. Tap **Connect** to verify that FieldGenius communicates with the receiver. You should see satellite tracking and a standalone position.

{% hint style="warning" %}
**Instrument profile mismatch** is the most common setup error. If you select the wrong manufacturer or model, FieldGenius may fail to communicate with the receiver or send incorrect commands. Always verify the exact model in your receiver's documentation.
{% endhint %}
{% endstep %}

{% step %}

#### Set up the internet connection

1. Go to **Survey > Instrument > Internet Setup** (or **Configure Internet**).
2. Select your internet connection method:
   * **Internal modem** — if your data collector has a built-in cellular modem.
   * **Bluetooth DUN / Phone tether** — for connecting via a smartphone hotspot.
   * **Wi-Fi / Direct IP** — if connected to a Wi-Fi network.
3. Verify that the device has an active internet connection before proceeding.
   {% endstep %}

{% step %}

#### Enter RTKdata.com NTRIP settings

1. In the Internet Setup screen, select **NTRIP** as the correction source type.
2. Fill in the following connection fields:

{% tabs %}
{% tab title="North America" %}

* **Caster Address:** `rtk.rtkdata.com`
* **IP Fallback:** `13.56.117.10`
* **Port:** `2101`
* **Username / Password:** From *RTK Credentials* in the internal dashboard (not website login)
* **Mountpoint (ALL CAPS):** `AUTO` (recommended) — or `AUTO_WGS84`, `AUTO_ITRF2020`, `AUTO_ITRF2014`
  {% endtab %}

{% tab title="Europe" %}

* **Caster Address:** `eu.rtkdata.com`
* **IP Fallback:** `3.73.41.96`
* **Port:** `2101`
* **Username / Password:** From *RTK Credentials* in the internal dashboard (not website login)
* **Mountpoint (ALL CAPS):** `AUTO` (recommended) — or `AUTO_WGS84`, `AUTO_ITRF2020`, `AUTO_ITRF2014`
  {% endtab %}

{% tab title="Australia" %}

* **Caster Address:** `aus.rtkdata.com`
* **IP Fallback:** `54.206.56.130`
* **Port:** `2101`
* **Username / Password:** From *RTK Credentials* in the internal dashboard (not website login)
* **Mountpoint (ALL CAPS):** `AUTO` (recommended) — or `AUTO_WGS84`, `AUTO_ITRF2020`, `AUTO_ITRF2014`
  {% endtab %}
  {% endtabs %}

3. Ensure **Send GGA Position** is enabled. RTKdata.com requires your approximate position (GGA) to compute Virtual Reference Station corrections.
   {% endstep %}

{% step %}

#### Connect and begin surveying

1. Tap **Connect** to start the NTRIP correction stream.
2. Monitor the solution status in the FieldGenius status bar as it progresses: **Autonomous > DGPS > Float > Fix**.
3. Once the status shows **RTK Fix**, you have centimeter-level accuracy. Convergence typically takes 15–60 seconds under open sky.
4. Begin your survey — use **Store Point**, **Stakeout**, or **Topo** as needed.

{% hint style="info" %}
FieldGenius displays the solution quality and number of satellites in the status bar. Verify **Fix** status before storing critical survey points.
{% endhint %}
{% endstep %}
{% endstepper %}

## Vertical reference

{% hint style="info" %}
Heights from RTKdata.com are **ellipsoidal**, not orthometric (mean sea level). FieldGenius can apply a local geoid model to convert ellipsoidal heights to orthometric. Configure this under **Project > Coordinate System > Geoid Model**.
{% endhint %}

## Troubleshooting

| Problem                      | Cause                                    | Fix                                                                                                    |
| ---------------------------- | ---------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| Receiver not responding      | Wrong instrument profile or COM port     | Re-check the manufacturer/model selection and verify the correct COM port under Instrument settings    |
| "Connection failed" on NTRIP | Incorrect host, port, or no internet     | Double-check the hostname, port `2101`, and that your device has active internet. Try the IP fallback. |
| Stuck on Float indefinitely  | GGA not being sent to caster             | Confirm **Send GGA Position** is enabled. Without GGA, VRS corrections cannot be generated.            |
| Mountpoint error             | Lowercase or misspelled mountpoint       | Enter `AUTO` in ALL CAPS. Do not use `auto` or `Auto`.                                                 |
| COM port busy or unavailable | Another app is using the serial port     | Close other apps that may be accessing the receiver's Bluetooth or USB serial connection.              |
| Poor accuracy even with Fix  | Bad sky view or incorrect antenna height | Move to open sky, re-measure the antenna height, and ensure the pole is level.                         |

## Tips for best results

* **Match the instrument profile exactly** to your receiver hardware. This is the single most important configuration step in FieldGenius.
* **Test the internet connection** before configuring NTRIP. A failed hotspot or cellular connection is easier to diagnose separately.
* **Save your NTRIP profile** within the project template so you do not need to re-enter credentials for each new project.
* **Use the satellite tracking screen** to verify at least 10–12 satellites before expecting a reliable Fix.
* **For Windows tablets**, ensure power management does not disable Bluetooth or Wi-Fi when the screen turns off.
