In the video, I did not use the saveconfig command at the end of the setup sequence. Make sure to use it at the end of your setup! Otherwise, the setup will be lost if you restart the UM98X module.
Fantastic! Do you mind sharing the name of your RTK2Go stations so I can include it in the list of stations resulting from this series? This is for a future video I am planning. Thanks!
@@oceanexplorationlab My RTK2Go station is ChezBlackRTK01 out of Queen Creek, Arizona. Also, do you have a recommendation on ESP32 boards? I'm using a generic one and while it works, it seems to drop WiFI quite often and requires a hard reset to start up again. Also, it's got an internal antenna that gets VERY poor connection even while in the same room as the router.
Your statin is added to my list. As for the ESP module, I suggest a ESP32-WROOM module with external antenna and USB-C like: www.aliexpress.us/item/3256806087645524.html?spm=a2g0o.productlist.main.109.668d33970iww2U&algo_pvid=c2c766d1-1931-4244-87d1-25e17ac4eb0b&algo_exp_id=c2c766d1-1931-4244-87d1-25e17ac4eb0b-54&pdp_npi=4%40dis%21USD%214.21%213.16%21%21%2130.42%2122.81%21%402103011017331761899805362e95b1%2112000036562388230%21sea%21US%214222747334%21X&curPageLogUid=Gn3dhBjgwNNw&utparam-url=scene%3Asearch%7Cquery_from%3A
Just wanted to say thank you. I've watched this video maybe 20 times as I tried to get my base station set up and it is finally up and running thanks to your help. Now I'm ready to start playing with the RTK rover parts in your next video. Thanks again.
@@oceanexplorationlab Just found out this morning that ESP32 is using NTRIPv1, took me one day scratching my head :-), now my station is up and running in onocoy 🙂 (don't know what happened with RT2Go, couldn't setup my account) Just waiting your next video on ESP32 NTRIP duo 🙏 Thanks again in advance.
I'm sure there are various options to achieve that. However, I haven't come across an open-source project specifically using the ESP32 for sending RTCM correction data via Bluetooth. It would definitely be a good option to connect to a computer. The Wi-Fi option I'm currently investigating is quite power-hungry but has the advantage of a longer range.
Thanks for info. It would be very interesting to do same thing with Quectel LC29H RTK module (it is an analogue of your module). It costs less then 50 dollars on Aliexpress.
The LC29H is a dual (L1 L5) band module, not a triple band module. Specifically for crypto, it will not optimize rewards. However, it may be interesting for a low-cost rover.
Good day sir, thank you for this great video tutorial. Please, can you help in making a practical video tutorial and how you put together and wired all the components used together. And secondly, is it possible to add Lora telemetry radio to this setup? Thank you in anticipation for your help and reply sir.
Thanks for your comment! I show how to wire the components in the videos. Could you let me know what specific details you feel are missing? As for adding LoRa, it's on my to-do list and should definitely be possible.
Nice series. One important question: Can I log the raw data (pseudoranges and Doppler measurements) using the GNSS module that you used? The reason I asked because I have my own algorithm to compute position and velocity and I want to use the raw measurements.
Cool! Thanks for your help. Can it store raw observations? For that you need storage, but esp32 wroom dont have it actually ... Maybe it will be better to use rasberry?
There may be. Also, the ESP32 can be configured as a Bluetooth bridge: www.ardusimple.com/ble-bridge-firmware-update/ . This may be better suited for field work.
Thank you for this info - this was super helpful. One follow up question. Why did you say that the 980 is better for a base station than the 982. I'm having trouble seeing what the difference is except the number of antennas.
Since the UM980 only needs to process data from one antenna, it can handle more satellites and generate faster positioning fixes. Additionally, the UM980 has about half the power consumption compared to the UM982, helping it stay cooler during operation. This makes the UM980 well-suited for base station applications.
Very good information again. If I understand this correctly. If I want to send correction data ONLY to MY Rover I do not need to setup a RTK2go account. My ESP32 board will be my local RTK Base...Correct?
I believe so. I haven't done it myself, but take a look at the XBee hookup guide for the various options: www.ardusimple.com/wifi-ntrip-master-hookup-guide/
Yes, this setup can be used as a GNSS base station for land surveying if that's your question. There's more to come in this series, which will hopefully address your questions. I suggest subscribing so you won't miss it!
Hello, I have a problem. Everything goes well until you connect the GPS module, then ESP32 starts to go into a restart loop and loses all settings, returning to factory settings. Has anyone had this?
Thank you for these very intersting video's. I also have a question, i do not have cable internet but use a phone set up as hotspot to connect to internet. Do you think it is possible to connect my diy basestation, like you showed, to sent the data reliable to RTK to go or other? Do you have any idea how much data gets sinds daily? Thank you
It is ~1kB/s or ~80MB/day. This should be no problem for a mobile hotspot. I use a mobile hotspot to receive RTCM corrections but never tried to send them this way.
hI, I have bought this um982 from aliexpress through another country( its on its way) as its very expensive here in india, need to attach Lora with or without esp32, as seen in another video with zed F9p board, how could you attach one... pls help. thanks in advance.
Once your UM982 arrives, you can set it up to send NMEA sentences via UART. After that, you should be able to use the same techniques shown in the video for the ZED-F9P to attach a LoRa module
@oceanexplorationlab thank you for responding, I would like you to help in the setup, incase I have difficulties in software installing ( as I am not a geek)
The ESP32 does not have enough processing power to support sending and receiving RTCM correction data from multiple devices simultaneously. However, you can connect a single GNSS base station to the ESP32 via UART, and the XBee's NTRIP caster function can distribute this data to several clients over a local network. For building a CORS station, it’s more practical to use free NTRIP caster services like RTK2Go and only use the XBee as a NTRIP server function.
No, the XBee is Wi-Fi only. There are Bluetooth options, which I hope to make videos about in due course, so hang in there and subscribe to receive the notification.

Hello! I had experimented several disconnections when streaming data with ESP_Xbee. Do you know what could be the issue? I switched to Str2Str and have not drop connection so far. Anyway, ESP32 y far more easy to setup and way more cheaper as well- Thanks in advance
Thanks for sharing your experience. Other than the obvious things like checking your power supply and Wi-Fi signal strength, I’m not sure what else could be causing the disconnections-it's hard to troubleshoot from afar! Personally, I haven't had any frequent disconnections with my ESP32 Xbee setup, but every situation is a bit different.
Hi there great video and Thank you for sharing your knowledge. Probably not the most clever question… building this kind of base station will it help me to get correction to my GNSS rover. Currently paying subscription fee, but in Sweden it seems to be quite expensive.
@@aivarg472 Relay is a strong word, but I will do my best to help when possible. I think the most important part is to nail down the position of your base station, either via Precise Point Positioning (PPP) or by using an established service like the one you have to find the initial position. Once you have the position, you set the location of your base station in the setup, and you should be good to go
