Unboxing
For building RTK Calibrated Surveyor Kit, there is no need for special tools nor nothing of the sort, by hand will be enough.
1. Start by mounting the receiver to the smartphone holder. You will need the velcro strap, the plastic case (ZED-F9P receiver with USB and Bluetooth 2.0 within) and the universal smartphone.
2. Place the case together with the smartphone holder with the SMA connector inversely positioned to the smartphone holder width adjusting screw. You may observe that the flat face of the case fits with the back of the smartphone holder. Fasten it together with the Velcro strap.
3. Next, assemble the clamp that will hold the smartphone holder to the pole. There are 3 different components that form the clamp.
4. Join the main parts of the clamp with the preferred screw. Each screw fits different screw holes within the clamp. You can screw in both and decide which may work best for you. Then, screw tightly together the rotating part of the clamp that will serve to rotate the smartphone holder to your preferred position.
5. Screw in the clamp to the smartphone holder. You can remove the unused screw of the clamp if convenient.
6. You can adjust freely the position of the smartphone holder by loosing up the rotating piece of the clamp and fixing it at your will.
7. You can adjust freely the position of the smartphone holder by loosing up the rotating piece of the clamp and fixing it at your will.
Now you have the first piece of your Surveyor Kit ready to connect with the other remaining two main pieces: your smartphone and the Calibrated Survey antenna.
9. You can now connect the smartphone to the receiver with the different cable sets of your kit. Connect the mini USB cable to the mini USB board connector of ZED-F9P receiver and the USB OTG cable suitable for your phone. Then, connect this to your phone.
10. You can leave the cables loose (above) or you may wish to knot up the cables or fast them with the Velcro strap to tighten them in and get them out of the way (below).
11. Now, you can proceed connecting the receiver to the Survey antenna. Connect the TNC-K to SMA cable (within Survey antenna box) to the SMA connector of ZED-F9P receiver
12. Fasten the clamp to the surveying pole.
13. Add on top of the pole the Survey antenna turning it delicately to the right until it stops.
14. Finally, connect the TNC-K end of the cable to the Survey antenna and adjust the surveying pole to the convenient height.
15. You now got your RTK Calibrated Surveyor Kit built and ready to work!
16.The kit can be used for about 6-8 hours with an average phone powering.
Note: If the you need more than this, use USB-C on-the-go (OTG) with external USB-C power supply (optional, not included in the package of the Surveyor kit) and a small external 1’000mAh powerbank.

How to use RTK Calibrated Surveyor Kit with Mapit GIS?
Firstly, pair your receiver to your Android smartphone or tablet.
- Power your RTK receiver by connecting USB cable to the power supply (smartphone/tablet/ compatible powerbank). If you get any pop-up message to connect the USB device with any app, you can ignore it.
- Enable the Bluetooth of your smartphone or tablet , and pair it with your RTK receiver.
When pairing your device, notice that it will appear as RTK_GNSS_***. The password is always 1234.
The pairing only needs to be done once. Unlike other Bluetooth devices, it won´t show as “connected” until you click “connect” button in an app.
- Place RTK antenna in a location with good view of the sky or near a window for testing the functionality.
Secondly, connect your receiver to Mapit GIS via Bluetooth.
- Open Mapit GIS. Go to Settings. Tap on External GNSS.
- Enable Direct Connection to External GNSS.
- In the pop-up window choose the device you paired in step 2.
- Back to the main screen, tap on the antenna icon you will see you are using External GNSS and with location and satellites information.
Thirdly, reach centimeter level accuracy.
In step 6, we can see the accuracy is not satisfactory yet. Because RTK receiver will need a base station or a correction service to reach centimeter level accuracy.
There is a build in NTRIP Client function in Mapit GIS, but it is not compatible with new Android version and it is not free. If it doesn’t work on your android device don’t worry, we have alternative GNSS Master app to overcome this limitation.
- In the menu tap NTRIP Client and set your corrections.
- GNSS Master app has built in NTRIP and PointPerfect capability to send corrections directly to your GNSS receiver.
“Mock Location” is a functionality of Android OS that allows you to “fake” the position of the internal GPS, and use instead the position of your fancy external RTK GNSS receiver.By using Mock location, you can receive centimeter accuracy on MapitGIS.
Follow ArduSimple tutorial How to use centimeter GPS with any Android app (mock location) to enable correction service on GNSS Master app and use mock location on MapitGIS.
- After accessing to NTRIP correction service you can see in MapitGIS that the accuracy is at the centimeter level.
Now you are ready to map and survey in a variety of applications from agriculture and forestry to road construction, geology, land surveying with centimeter level accuracy on your Android device.
How to use RTK Calibrated Surveyor Kit with Other software?
If you need to use Surveyor kit with any other software, we will explain how to configure Ardusimple RTK receivers to be used as mock location for Android smartphones/tablets in order to get centimeter position accuracy.
If you are not familiar with the term, mock location means that you cheat your Android device to use an external GNSS receiver as if it was its own internal one. This has the advantage that any GPS/GNSS app that works with your Android device can benefit of centimeter level accuracy.
Firstly, install GNSS Master app and enable mock location in your Android Device.
This step only needs to be done once.
- Install GNSS Master app on your Android device from the Google Play Store. When you first open the app, you will be asked to allow certain permissions to GNSS Master.
- Location Permission
- Display Notifications
- Once you accept the permissions, the Status page will load, showing the current status of the app. We will configure it later.
- To enable mock locations in Android we will need to get Developer permissions. The procedure may vary slightly between different Android versions and smartphone models (you can Google your “Smartphone model + enable mock location” if you can’t find the exact options).
- On Android 4.1 and lower, the Developer options screen is available by default. On Android 4.2 and higher, you must enable this screen. To enable developer options, tap the Build Number, MIUI version or similar option 7 times.
- You can find this option in one of the following locations, depending on your Android version:
- Settings –> About Phone –> Build Number
- Settings –> System –> About Phone –> Build Number
- Once you have access to Developer options, you can go to Settings –>Additional Settings and at the bottom you will find Developer options. In this big list, tap Select mock location app and select GNSS Master from the list.
- Connect the GNSS antenna to your device, in a location with good view of the sky, or near a window for testing the functionality.
Secondly, connect the RTK receiver to your Android device.
The best option (if your device supports it) since you can power and communicate with it at the same time.
- Connect RTK receiver with your Android device with USB OTG cable.
- Open GNSS Master app. Check Mock Location and Output to SW Maps.
- Click the gear icon on the right side of GNSS Receiver Connection to enter the setup menu.
- Choose USB Serial at Mode.
Set Baud Rate to 115200 bps (if you ordered your ArduSimple Proofessional kit before 09.10.2023, set Buad Rate to 38400 bps. If you use a different receiver, the Baud Rate should match with your receiver configuration).
At Connected USB Device, it will automatically recognize your receiver with name ***** USB UART.
- Press CONNECT.
- Power your RTK receiver by connecting USB cable to the power supply (smartphone/tablet/ compatible powerbank). If you get any popup message to connect the USB device with any app, you can ignore it.
- Enable your smartphone/tablet Bluetooth, and pair it with your RTK receiver. When pairing your device, notice that it may appear as RTK_GNSS_*** or as a generic MAC number (e.g.: F0:0A:95:9D:68:16). The password is always 1234. The pairing only needs to be done once.
- Open GNSS Master app.Check Mock Location and Output to SW Maps.
- Click the gear icon on the right side of GNSS Receiver Connection to enter the setup menu.
- Choose Bluetooth at Mode. In Paired Devices chose the one you paired in step 8. Press CONNECT.
- Go back to main menu. Now you should see in GNSS Receiver Connection it says Connected and with data transfer.
- Open Correction Input by clicking on the gear icon.
- In Mode choose NTRIP Client and press the + button next to NTRIP Connections.
- Set your NTRIP Client credentials (Caster IP, Caster Port, Username and Password). If you don´t know how to do it, have a look at this tutorial.
Press SAVE.
- Press CONNECT. In Status you will see GNSS Receiver Connection and Correction Input showing Connected and with data communication.
- You can check your location and available satellites in Skyplot.
- Open your favorite GPS/GNSS application and use it as usual.
You will be using the external RTK GNSS receiver instead of the smartphone/tablet internal GPS receiver. Following image is the example of SW Maps.
- We have tested this functionality with many apps, you can find them in this link.
If you test it in other apps, you can send us an email at info@ardusimple.com and we will add it to the list.
