Stonex S950 & S1000 NTRIP Setup: Cube-a and S950 Web UI

Connect the Stonex S1000 or S950 to RTKdata NTRIP in Cube-a 7, or the S950 in its Web UI: receiver SIM or controller internet, AUTO mountpoint, GGA and tilt.

To set up NTRIP on the Stonex S950 or S1000 with RTKdata, open Stonex Cube-a on the Android controller, go to Device > Working Mode > Rover, set the Datalink to Internal Network (SIM in the receiver) or Phone Network (internet from the controller), and enter the RTKdata host for your region (rtk.rtkdata.com, eu.rtkdata.com or aus.rtkdata.com) in IP:, 2101 in Port:, your RTK credentials under CORS Account and the AUTO mountpoint from the loaded mountpoint list. The S950 can also be set up in its Web UI at 192.168.10.1 under Working mode, with the same values in Connection Settings. The S1000 is set up in Cube-a only.

The S1000 and S950 are Stonex GNSS rovers with IMU tilt compensation, cameras for AR stakeout, a laser distance meter and a modem for a Nano SIM. Stonex describes Cube-a as compatible with all Stonex GNSS receivers.

Stonex has not published an S1000 user manual (September 2026). The Cube-a steps are the same as for the S950 and follow the Cube-a 7.0 user manual (April 2025). The S950 Web UI steps follow the S950 user manual (September 2025, Ver. 1.0). Current app version when this page was written: Stonex Cube-a v7 7.2.05 (Google Play, 31 July 2026). Labels can differ in other versions.

These are the values you enter in Cube-a or in the S950 Web UI, and the field names in bold match the software. Choose 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.

  • Enter only the hostname in IP: or Server Address, without http:// and without :2101. The port has its own field.

  • Use the hostname first. The Cube-a manual does not say whether the rover field IP: takes a hostname, and the S950 Web UI labels Server Address as an IP address. If the hostname is rejected or does not connect, enter the IP fallback for your region instead.

  • In Cube-a, load the mountpoint list and select AUTO. The list can show more entries than AUTO: select AUTO. In the S950 Web UI you can type AUTO in capitals.

  • One set of credentials allows one connection at a time. Keep only one connection path active on the receiver (for example, turn off Automatically connect to network: on Internal Network while you test Phone Network); a second rover needs its own data stream, see Account & Credentials.

  • If Cube-a still holds an entry from another correction service, do not reuse it. Add a new entry for RTKdata or type the values into the fields.

RTKdata streams RTCM 3.2 with MSM4 messages (1074, 1084, 1094, 1114, 1124, 1134) and the station message 1005. The S950 manual states: "In Rover mode, S950 automatically recognizes the RTK corrections format between: RTCM 3.2, RTCM 3.0", so the S950 needs no format setting. For receivers that accept only legacy RTCM messages, see Correction format.

Requirements

  • Stonex S1000 or S950

  • Android controller with a licensed Stonex Cube-a 7, required for the S1000. Cube-a cannot be unlocked without its license code, and the license is bound to the Android device it was registered on: Stonex states that "you cannot use the same purchase code to unlock a copy of the program that is installed on another device". Take the controller that holds the license into the field.

  • For Internal Network: a Nano SIM without PIN with mobile data, and your carrier's APN. The S950 manual says to insert the card while the receiver is off and to lock it by sliding the metal cover. The S1000 brochure lists a Nano SIM as well; use a card without PIN there too. Test a new SIM in a phone first: PIN off, mobile data working, enough data volume.

  • For Phone Network: mobile data on the controller, from its own SIM or from a Wi-Fi hotspot

  • For the S950 Web UI: a smartphone or PC with a browser

  • RTKdata account with active RTK credentials (username starts with rtk)

  • RTKdata coverage at your site: check the coverage map before you go out

  • Open sky for the first position, and a survey pole for tilt compensation

On this page, the S1000 is set up in Cube-a only. The S950 Web UI steps apply to the S950 alone.

Stonex S890: the printed Stonex Surveying Products Catalog 2026 lists the S890 as "S890 5W RADIO". Stonex has not published a user manual for the S890 (September 2026), so this page does not cover its setup.

How do you set up NTRIP on the Stonex S950 or S1000 in Cube-a?

To connect the S950 or S1000 to RTKdata in Cube-a, connect the receiver under Device > Communication, open Device > Working Mode > Rover, pick Internal Network or Phone Network under Datalink, fill in the RTKdata host, port 2101, your RTK credentials and the AUTO mountpoint, then set the antenna height and tap Apply. The steps are the same for the S950 and the S1000.

1

Insert the SIM (receiver SIM only)

Skip this step if the receiver gets internet from the controller (Phone Network).

  1. With the receiver switched off, insert a Nano-SIM without PIN code into the SIM slot. On the S950, use the Sim card slot and lock the card by sliding the metal cover.

  2. Switch the receiver on. On the S950, hold the power button until you hear a beep.

  3. Have your carrier's APN at hand. Cube-a asks for it in the network settings.

2

Connect Cube-a to the receiver

  1. Tap Device at the bottom of Cube-a and open Communication.

  2. Set Device Type: to Stonex GNSS and Communication Mode: to Bluetooth.

  3. Tap Search, select your receiver's serial number in the Bluetooth Name column and tap Connect.

QR scans the code on the bottom of the receiver, but only after a Bluetooth search: Cube-a looks for the serial number among the devices it has found. For AR stakeout, the cameras or the laser over Wi-Fi, see How do you keep corrections running with AR stakeout, camera or laser? below.

3

Open the rover settings

Open Device > Working Mode > Rover. The page Rover mode settings opens with the sections Options, Datalink, Antenna Parameters and Satellite Systems.

4

Choose the internet route and enter RTKdata

Under Datalink, open the Communication Mode: drop-down and select the route, then tap the button below the drop-down to open its settings page. See Receiver SIM or controller internet if you are not sure which route fits.

The page Rover network settings opens.

  1. Connect Mode: select NTRIP.

  2. Connection Options: set GGA Upload Interval(s): to 1 (the manual gives 5 seconds as the default, which also works), turn Automatically connect to network: on and leave Network Relay: off.

  3. APN Settings: select your carrier under Operator:, or select Custom and enter APN Name:, plus User: and Password if your SIM provider requires them. Do not keep example values.

  4. CORS Settings: under Name:, add your own entry for RTKdata or fill in the fields directly; do not use a saved entry of another correction service. Enter the host for your region in IP: and 2101 in Port:.

  5. CORS Account: enter User: and Password from RTK Credentials, and tick Show password to check them.

  6. Get MountPoint Settings: tap Get Mountpoint (RTK network). Cube-a downloads the list through the receiver's network or through the controller's own mobile connection. If the receiver SIM is not online yet, turn on Phone network access: first.

  7. MountPoint Settings: select AUTO under MountPoint:. The list can show more entries than AUTO: select AUTO.

  8. Tap OK.

The controller needs internet from its own SIM or from a hotspot. The page Send diff. from controller opens.

  1. Connect Mode: select NTRIP.

  2. CORS Settings: check Name: first and do not keep a saved entry of another correction service. Add your own entry for RTKdata or fill in the fields directly: the host for your region in IP: and 2101 in Port:.

  3. CORS Account: enter User: and Password from RTK Credentials, and tick Show password to check them.

  4. MountPoint: tap GET ACCESS POINT, then select AUTO under Corrections. The list can show more entries than AUTO: select AUTO.

  5. Turn Automatically connect to network: on and set Send GGA delay [sec]: to 1. Leave Fake GGA coordinates, Forced GGA and Record diff. corrections off; the Cube-a manual describes the recording as "only for debug".

  6. Tap Start. The Receive: bar fills when data arrives. Tap OK.

Both pages show Notify when base coordinates change: under CORS Settings. With AUTO, the message it shows is expected after the caster switches to a closer station, and it is not an error.

AUTO needs your position. The AUTO mountpoint chooses the base station from the receiver's position, which the receiver sends as NMEA GGA at the interval you set. The Stonex manuals document no separate GGA switch, so do not leave the interval empty or at 0. Without a position, the receiver logs in but receives no corrections, see NTRIP & GGA Essentials; the next step shows when to connect. Leave Fake GGA coordinates and Forced GGA off. The Cube-a manual describes them as "only for test", and with a fake position AUTO picks the base station for the wrong place.

5

Set the antenna height and apply

  1. Back on Rover mode settings, set Measured Height: and Measurement Type: under Antenna Parameters.

  2. Tap Apply.

  3. Optional: tap Save to Configurations to reuse the setup later or in a new project without entering all parameters again.

Wait for your own position first. Put the receiver under open sky and wait until Cube-a shows at least SINGLE before you tap Apply (with Phone Network, before Start). Started indoors, in a vehicle or right after power-on, the receiver has no position to send, and AUTO cannot assign a base station.

6

Wait for FIXED

Stay outside with open sky and check the solution as described in How do you know corrections are really arriving? below.

Receiver SIM or controller internet: which Cube-a datalink do you need?

For RTKdata corrections on the S950 or S1000, choose Internal Network when the receiver has its own Nano SIM with mobile data, and Phone Network when the internet comes from the controller, from its SIM or a Wi-Fi hotspot. With AR stakeout, the cameras or the laser in use, Internal Network is the more robust choice.

Only if Android keeps mobile data active on Wi-Fi

  • Phone Network is a rover mode: the corrections come in over the controller's internet and Cube-a passes them to the receiver. Stonex notes that "This communication mode is only for rover."

  • With Phone Network, the S950 manual says Cube-a sets the receiver datalink to Bluetooth. That is normal, see the Web UI section below.

  • If the receiver SIM does not connect, a quick test with Phone Network shows whether the problem is the SIM or APN: if corrections arrive over the controller, check the SIM, the APN and whether your carrier allows port 2101, see Troubleshooting & FAQ.

How do you set up NTRIP in the S950 Web UI?

To connect the S950 to RTKdata in its Web UI, connect a phone or PC to the receiver's Wi-Fi hotspot, open 192.168.10.1, log in, and on the Working mode page set System Mode to Rover, Current Datalink to Network, the SIM under Internet Settings and the RTKdata values under Connection Settings, then save. This path is documented for the S950 only; set up the S1000 in Cube-a.

No GGA field in the S950 Web UI. The network page of the S950 Web UI has no GGA setting, and Stonex does not document whether the receiver sends its position to the caster when it is set up this way. If the rover stays on SINGLE after the Web UI setup, set it up in Cube-a with Internal Network and GGA Upload Interval(s): 1 instead.

Use one setup path. Do not switch back and forth between Cube-a and the Web UI. Settings applied from Cube-a change the receiver datalink: with Phone Network, Cube-a sets it to Bluetooth, so the Web UI then shows Current Datalink Bluetooth. That is normal according to the S950 manual. Do not change it back to Network in the Web UI.

1

Log in to the Web UI

  1. Insert the Nano SIM as described under Requirements, with the receiver switched off, then switch the S950 on.

  2. Connect the phone or PC to the receiver's Wi-Fi hotspot. The hotspot name is the receiver serial number.

  3. Open 192.168.10.1 in a browser.

  4. On Login, enter User admin and Password admin, the standard credentials in the S950 user manual, and tap Submit.

2

Set the rover and the network datalink

On the page Working mode, set System Mode to Rover and Current Datalink to Network.

3

Set up the SIM

Under Internet Settings:

  1. Set Network Link to SIM Card Network.

  2. Enter your carrier's APN. It is required.

  3. Fill in APN User and APN Password only if your carrier requires them.

4

Enter the RTKdata connection

Under Connection Settings:

  1. Set Connection Mode to NTRIP.

  2. Server Address: the host for your region, for example eu.rtkdata.com. If it does not connect, enter the IP fallback for your region from the tabs above.

  3. Server Port: 2101.

  4. Mount Point: type AUTO in capitals. You can also tap Get Mountpoint and select AUTO in Select Mountpoint; this needs a working internet connection and the server address and port set first.

  5. User and Password: from RTK Credentials, not your website login.

5

Save and check

  1. Tap Save at the bottom of the Working mode page (the Stonex manual shows it there for the UHF datalink).

  2. Open Information > Network and check Caster Address (your regional host or IP) and Mount Point AUTO. The same section also lists Signal Level and IMEI, which help when you check the SIM connection.

  3. The Dashboard shows the working mode, the satellites in use, the quality of the solution and the expiry date of the receiver registration. Wait outside with open sky for FIXED.

How do you keep corrections running with AR stakeout, camera or laser?

On the S950, Cube-a connects to the receiver over Wi-Fi for AR stakeout, the cameras and the laser, so take the RTKdata corrections through Internal Network with a SIM in the receiver. Phone Network with a SIM in the controller works only if Android keeps mobile data active while on Wi-Fi, and a smartphone hotspot cannot provide the internet in this mode.

Stonex requires the Wi-Fi connection for AR stakeout on the S950, and a Stonex dealer FAQ states the same for the S950 laser and cameras.

  1. In the Android Wi-Fi settings, connect the controller to the receiver's hotspot. On the S950, the hotspot name is the receiver serial number.

  2. In Cube-a, open Device > Communication, set Communication Mode: to the Wi-Fi option and tap Connect.

  3. Set up the corrections with Internal Network, as in the Cube-a steps above.

  4. Only if you need Phone Network with a SIM in the controller: turn on the Android developer option Mobile data always active, so the controller keeps using mobile data while its Wi-Fi is connected to the receiver.

  5. Do not use a smartphone hotspot as the controller's internet here. The dealer FAQ states that receiving corrections through a smartphone hotspot is not possible in this mode.

On the S950, connect over Wi-Fi before you start. The same dealer FAQ reports that choosing a laser measurement while Cube-a is connected over Bluetooth makes Cube-a switch to Wi-Fi, which can cause conflicts.

  • AR stakeout: the S950 manual asks for the control panel facing you, the Wi-Fi connection and active tilt correction. In Cube-a, open Survey > Point Stakeout, select the point, tap Stake point and then AR.

  • S950 laser: open Survey > Point Survey, choose the point type Point by GPS+Diastimeter and tap Store. Cube-a stores the coordinates, not the measured distance.

  • S1000: the S1000 brochure lists AR stakeout and a laser distance meter. Stonex has not documented the Cube-a menu for the S1000 laser.

Turn on tilt compensation

Tilt compensation works only with a FIXED solution. Turn it on in Cube-a and calibrate the IMU once with the correct pole height.

  1. Open Configure > System Settings > Sensor Options (or Calibrate > Sensor Options) and select Pole Tilt Correction ("Requires a FIXED solution"). Tap OK.

  2. In survey mode, after FIXED, follow the initialization screens: draw a circle on the ground with the pole tip, then move the receiver back and forth for a few seconds, rotate it by 90 degrees and repeat.

  3. To calibrate, open Calibrate > Calibrate Sensor (screen IMU Calibration). A FIXED solution is required. Set the pole to 1.8 m and enter the same height in Cube-a. Slowly move the pole back and forth to initialize the IMU, then tap Start. Keep the pole tip on a fixed point on the ground and tilt the receiver back and forth in four directions, turning it by 90 degrees for each new section, until each section shows 50/50, reaching at least 45 and not more than 60 degrees, until Calibration complete appears.

These steps come from the S950 user manual. On the S1000, follow the calibration screens Cube-a shows: the Cube-a manual says the Calibrate Sensor page depends on the connected receiver, requires a FIXED solution and warns that an incorrect antenna height makes the calibration inaccurate.

How do you know corrections are really arriving?

RTKdata corrections are really arriving on the S950 or S1000 when Cube-a shows FLOAT or FIXED and the differential correction age stays low, which the Cube-a manual gives as generally under 5 seconds. DGNSS alone does not prove an NTRIP connection, because Cube-a also shows it for corrections from SBAS satellites.

Open the solution from the Cube-a status bar or under Device > GNSS Status:

Solution
Meaning (Cube-a manual)
What to do

NO FIX

No position: not connected to the receiver, or no satellites

Check the Cube-a connection and the view of the sky

SINGLE

No differential corrections

Check SIM or controller internet, credentials, AUTO and GGA

DGNSS

Corrections from SBAS satellites, or from the base without a better solution

Do not treat it as proof of NTRIP; wait under open sky

FLOAT

Corrections arrive, RTK not solved yet

Stay under open sky and wait

FIXED

RTK fix, the final solution

Start measuring

  • Differential correction age in GNSS Status is the delay of the incoming corrections. In RTK mode it is generally under 5 seconds (Cube-a manual); higher values point at a slow data connection.

  • With Phone Network, the Receive: bar on Send diff. from controller shows whether data is flowing.

  • On the S950, the datalink indicator on the front panel is green when "the differential corrections are being received/transmitted" (S950 manual).

  • The differential mode in GNSS Status always reads AUTO, because the receiver decodes the corrections. It is not the mountpoint.

  • If the solution stays on FLOAT for a long time although corrections arrive, use Device > RTK Reset. Stonex: "This function forces the GNSS board re-initialization".

Coming from an S980A or S900A? The Cube-a manual lists a-RTK, which keeps RTK precision for a while after the corrections stop, as "only available with the GNSS A-Series receivers". Do not rely on it with the S1000 or S950. On the S950, RTK Timeout [6-8100] in the Web UI Satellite settings sets how many seconds without corrections drop the fixed solution; Stonex's screenshot shows 30, so do not set it lower.

Which coordinate system should you use with AUTO in Cube-a?

With the RTKdata AUTO mountpoint, choose the Cube-a project coordinate system that matches the datum AUTO delivers for your region, for example NAD83(2011) in the USA or ETRS89 (realization ETRF2000) in Europe; do not add ITRF Conversion and do not choose RTCM1021-1027.

Coordinate system and heights with AUTO

  • What AUTO delivers: the regional datum for the position in your GGA, for example NAD83(2011) epoch 2010.0 in the USA, NAD83(CSRS)v7 epoch 2010.0 in Canada, ETRS89 (realization ETRF2000) epoch 2010.0 in Europe and GDA2020 epoch 2020.0 in Australia. Regions not listed get WGS84(G2139) at the mid-year epoch. AUTO_ITRF2020 and AUTO_ITRF2014 deliver ITRF2020 and ITRF2014 at the current epoch, and AUTO_WGS84 delivers WGS84(G2139) at the mid-year epoch. The full table is in Coordinate Systems & Datums.

  • Project coordinate system: when you create the project, tap List and pick the system that matches the AUTO datum for your region. For an existing project, change it under Configure > Coordinate System.

  • Coordinate system parameters type: do not select RTCM1021-1027. The Cube-a manual reserves it for networks that send these messages "if the CORS you use sends them out"; RTKdata sends 1005 and MSM4, not 1021 to 1027.

  • ITRF Conversion: leave it off with AUTO. The Cube-a manual warns that "this conversion is applied to all points in the current project".

  • Heights: RTKdata delivers ellipsoidal heights. For orthometric heights, enable a geoid under Configure > coordinate system > Geoid files; your own geoid files go into the stonexcube > Geoid folder. See Understanding Heights.

  • Offset against control: a consistent offset of 50 cm to 1 m against local survey control usually means a datum mismatch, see Why Your Coordinates May Be Offset.

Can I set up NTRIP on the Stonex S1000 without Cube-a?

Not with documented steps: Stonex has not published an S1000 user manual (September 2026), so RTKdata documents the S1000 NTRIP setup in Cube-a only, with Internal Network or Phone Network. The S1000 brochure lists a web interface, but its address, login and fields are not documented. Do not use the S950 Web UI values on the S1000.

Why does the S950 Web UI connect but the rover stays on SINGLE?

The RTKdata AUTO mountpoint needs the S950 position (GGA) before it sends corrections, and the S950 Web UI has no GGA setting; Stonex does not document whether the receiver sends GGA when it is set up there. Check outside with open sky, then check the APN, the credentials, Mount Point AUTO and, if the hostname does not connect, the IP fallback. If the rover still stays on SINGLE, set it up in Cube-a with Internal Network and GGA Upload Interval(s): 1.

What is the default login of the S950 Web UI?

The S950 Web UI login is User admin and Password admin (S950 user manual); these are not your RTKdata credentials, which go into User and Password under Connection Settings. Connect to the receiver's Wi-Fi hotspot (named after the serial number) and open 192.168.10.1. Other Stonex receivers use different standard credentials, so do not carry them over to the S950.

Why does Cube-a warn that the base coordinates have changed?

Cube-a warns because the RTKdata AUTO mountpoint can hand you over to a closer reference station as you move, see NTRIP Server Settings, and Cube-a shows a warning each time the base coordinates change when Notify when base coordinates change: is on. With AUTO this warning is expected and is not an error.

Does a smartphone hotspot work while the S950 laser or camera is in use?

No. According to a Stonex dealer FAQ, RTKdata corrections cannot come through a smartphone hotspot while the S950 laser or cameras are in use; in this mode Cube-a is connected to the S950 over Wi-Fi. Use a SIM in the S950 (Internal Network), or a SIM in the controller (Phone Network) with the Android developer option Mobile data always active turned on.
