Great series. I just ordered my 980 chip and antenna for my base station. I’m looking forward to experimenting with various rover projects I have in mind
@@kuwerty2kuwerty23 Sure I purchased EM-980D1 Unicorecomm Multi-frequency High Precision RTK Positioning GNSS Module GPS BDS GLONASS Galileo UM980 Replace ZED-F9P both were approx. $169 USD. I have to order a another one for my rover but I wanted to get the base station up and working first.

@@whiskerrub If you follow the provided diagram and omit the LEDs, nothing will be connected to the 3.3V pins on the ESP. Power will be supplied from the UM980 module to the 5V pins on the ESP32. Ensure your individual components function properly when connected to USB. If they are still working, you should be fine.
@@whiskerrub Leaving out the LEDs initially reduces the potential for errors. Once the ESP is powered up and you've confirmed that the other wires are correctly connected, you can then reinstall the LEDs.
Programming the module through a mobile app is possible in principle, but I have no immediate plans to do so. Please let us know if you find a way. The same applies to the other two questions.
I've been enjoying your RTK playlist and believe I have a use case to stake out coordinates of two lots of land I own. The coordinates I can generate from a known coordinate set from a survey I have of another adjacent lot I own (complete with real survey markers). What I would like to know is how can I take your system setup, walk my land with the rover and put stakes at the coordinates displayed from the rover/base output I would use an app like Qfield or ArcGis field map on the iphone I think unless there is a more suitable one. I also use QGIS and know enough about that tool to be dangerous. lol
Can we able to send RTCM Corrections between base and rover ESP32s with wifi or Bluetooth. and Remove the need for RTK2go? Process will be more simpler. Anyway this video helped me a lot, thankyou for doing this
@@oceanexplorationlab absolutely please do and 1 more thing, with 982 and 2 antennas utilized can the rover determine altitude and axis rotation. I want this data for ROS in raspberry pi for SLAM. Ras pi is onboard on UAV. Thankyou.
If you use the ESP32 XBee code binary, yes, you will have to use a second microcontroller to display the coordinates on an OLED. Alternatively, you can try to modify the source code if you are comfortable with the Espressif IDF (I am not).
If you can do a video on this it would be of interest. Like the idea of a second esp32 or a raspberry pi. From reading last night looks like you get the uart from either TCP or USB.
did I understand correctly, 2 esp boards are needed, one for the base station, the second for the rover? Also, there must be wi-fi coverage on the rover to receive data from the base station?
Yes, that's correct-in the configuration I'm currently exploring, you need two ESP boards: one for the base station and another for the rover. The base sends RTK correction data to the rover, so there does need to be a stable connection between the base and the rover. However, there are other options to send telemetry data besides WiFi, such as using LoRa, cellular modules, or Bluetooth, depending on your specific use case and range requirements.
Thank you for your videos. I did not find how the UM980 "understands" that RTCM needs to be accepted on COM2. There are RTCM broadcast commands to the specified port in the documentation, but there are no commands indicating RTCM reception to a specific UM980 port. I also didn't find the answer in your video, you just plug ESP 32 into COM2 and everything works) How does it work? Thank you.
The module accepts RTCM corrections on all UART ports by default. In this setup, COM2 is configured to send NMEA comments to the ESP32. Since RTCM corrections are accepted on any port, there's no need for a dedicated command to specify reception on COM2.
Excellent presentation series of these type of gnss. I would like to ask if possible to explain how to do PostProcessingKinematics (PPK) eg. what messages we need to enable etc.
Hello! I want to make the same connection, but via SiK Telemetry Radio. Rover receives corrections over the wires, but does not work through the radio. Using the utility, I can see that the corrections data (I hope) is being sent to Rover radio. But UM982 behaves as if there are no corrections. Do you not know how to debug the system? I haven't found how to see what the UM985 gets. Thank You!
@@oceanexplorationlab I have solved the issue. It turns out that Sick Telemetry Radio does not transmit data to the port if it is connected to a computer via USB. The LEDs are flashing, the console sees incoming data, but they do not go to the port. Thank you!
Hello! The coordinates of the base station (longitude and latitude) are provided by the GNSS module as part of the correction data. When configuring the UM980 as a base, you’ll need to provide those coordinates. In my video, I used the automatic determination of the base coordinates via the base time 60 2 2.5 (Self-optimizing Base Station Mode) command. I recommend consulting the Unicore Reference Commands Manual to understand how to provide the coordinates for your base using the "Fixed Base Station with Precise Coordinates" mode. As for connecting an OLED monitor, this won’t be possible unless you modify the source code of the XBee, which is available on GitHub. You would need to make changes there to integrate the OLED.
This series has been great! I’ve set up my base and had it online for a couple weeks now. I want to set up and build a survey stick rover next. I have ordered the parts and am awaiting them. I’m not sure yet how to get the rover points saved and plotted on a map. I’m thinking about using the sw maps app on my phone to do this. I would like to be able to save two points then generate a line between them. Once I have the line I want to use the rover to locate that line in the field. In order to use the rover in sw maps it must be connected to the phone with Bluetooth. Any chance you will be covering this in future videos? Thanks again for all the help so far!
Hi I'm thinking of bulding stick rover as well. Can you tell me what kind of antenna you have purchased? I've saw that on aliexpress there are those regular ones and small black ones and I wonder is there any difference. The smaller one would be a better fit for stick RTK rover if they have the same specs I think. Also are using UM980?
I’m using a stk-107 for my base station and it gets great reception. For my rover I purchased the ag-35 antenna but it hasn’t arrived yet. I ordered it because the housing looks bigger I plan to house all the electronics inside of the antenna cover and just have a plug to supply battery power to it. Iv got all the code working and am able to communicate with the esp32 via Bluetooth on my iPhone. I’m still waiting on the um982 and rest of the parts to get here from china. I can sucessfully pass nmea and Rtcm messages and get an RTK fix.
Hi do you know if it is possible to create a UM980 based rover that will have a BT option to connect to a smartphone or other device and read the X Y coordinates there? Also for rover do I need UM980 or UM982?
Certainly, you can transmit coordinates through UART to a Bluetooth UART bridge and connect it to your phone. I plan to experiment with this when time permits and will post a video once I have figured it out.
@@oceanexplorationlab I came across this one as well th-cam.com/video/0Q_4q1zU6Zc/w-d-xo.htmlsi=4UQtSwKcHDdCxnbK not sure if it’s relevance on the subject as I am definitely very fresh to all of this but having lots of fun trying to make it all work. Greatly appreciate your support! I will definitely check out the video. Now that I have a working RTK2go mount point, i want to duo like you pointed out, again not quite sure what I need for that. Have a great day, and again thanks for your support.
This option is just some kind of stupidity. What is ESP 32 here for, what would that be?(only receive corrections and do not use them any further) If for some RC model, the GNSS module is connected directly to the autopilot(Ardupilot, PX4, etc.) For the rover, it is enough to connect the Bluetooth module and use the app on your phone/tablet.
While your application might not need an ESP32 if you're getting the RTCM stream via an autopilot, in the absence of a more advanced autopilot, the ESP32 is actually a perfectly fine solution to receive the necessary correction data and send it to the UM980. For a survey and plotting positions on a map, there's no need for an autopilot. I'm not sure why you say it isn't used-it's specifically there to handle the corrections. Also, there's no need for dismissive language-we're all here to learn and share knowledge.

You can use it if someone reliably streams correction data to RTK2Go, but you must be within a 20-kilometer range.
