What a great video. Thank you very much for taking the time and trouble to explain the setting up of these units. I bought a UM980 to use with Onocoy. However, until I get my antenna mounted on my roof, I want to experiment with using the UM980 as a Rover. I get so far but cannot get an RTK fix after connecting to my local mount point (RectoryFarm on rtk2go). After start-up the unit will switch to RTK float mode, but even after several hours, RTK fixed is not achieved. if you have any pointers, I would be very pleased to hear them. Thanks again.

How far away is it RectoryFarm from your location? If the station is too far, you might want to consider lowering the certainty level of the RTK solution using the following command: CONFIG RTK RELIABILITY 3 1. The default is 3, and lower numbers indicate a less reliable but acceptable RTK solution. Also, once you have your own base station up and running, please let me know the name of your new station. I'm planning to compile a list of all the base stations that come to life because of this video series.

@@oceanexplorationlab Many thanks for the reply. I'll check the distance between myself and RectoryFarm. I'll also try lowering the reliability setting. Yes, I'll let you know when I get up and running.

I've set up a UM980 base station and a UM982 rover by following your videos. Thanks so much! Unfortunately, my rover doesn't seem to be using RTK. I'm not getting the second solid blue light that you show in the video, and logs coming from running GPGGA 1 show that my GPS quality is 2, differential GPS. It looks like it should be 4 or 5 for RTK. I also checked RTKSTATUS 1, and it looks like I'm getting a 0 value for 'Calculate status' which indicates no differential data. Just to confirm, my rover's accuracy is still hovering in the 2-5m range. I'm not sure if something could be misconfigured?

This is a tough problem to diagnose from a distance. Do you have the RX and TX LEDs connected? If not, I suggest you do so and see if data is sent from the ESP to the UM98X.

@@oceanexplorationlab For some reason my previous reply disappeared. Darn RU-vid. For ease of trying things out, both my base and rover are connect to my laptop and connected to separate sessions of UPrecise. My base station seems to be working fine, as I see it in RTK2Go with mountpoint 'pacifica'. I even tried the next nearest station 'Tiburon-0001' on the rover and no luck. It seems that there is some issue getting the correction data from UPrecise to the receiver, although the RTCM Input and Output sections are set up like yours in this video. I now notice that an error appears in the data stream when I connect (although everything is green): $command,ICY 200 OK,response: PARSING FAILD NO MATCHING FUNC ICY*76

If I understand you correctly, you are getting the response: "$command, ICY 200 OK, response: PARSING FAILED NO MATCHING FUNC ICY*76" from the rover module. If this is the case, something is wrong because the rover should only receive RTCM data, which is binary, and should only appear in the RTCM monitor, not in the 'Data Stream' window. Make sure you set the output port in the RTCM monitor to the same port your receiver is connected to. This is easy to miss and will produce the results (minus the error message) you are describing.
@liammcfadden7760
@liammcfadden7760 2 дня назад
@@oceanexplorationlab Yes, that error appears only when I first connect to the RTCM data stream. It looks like ICY 200 OK is the first message sent from the NTRIP Caster, which is somehow making it to the Data Stream panel. I have confirmed that the RTCM Output COM port is set correctly to the same port my receiver is connected to. I'm at a loss here. Maybe my issue is a newer version of UPrecise?

I just tested it with the newest version of UP, and it works fine for me. Maybe try using two different PCs? Also, do you see the binary data stream in the RTCM monitor on the rover-facing UP instance?

Please take a look at making a rtk rover with a Bluetooth chip.

Hi, great video! Is there any software that will allow me to navigate to know coordinates using my own rover? Let's say I know coordinates of the point were corner of my fence should be and I want to use my rover to find that?
@oceanexplorationlab

Thanks for watching! A popular option is Ardupilot which allows you to input waypoints, like the coordinates for your fence corner, and it will guide your rover to that exact location.

On Uprecise there is a Message/Nmea/Hdt section, but is always in light gray, like 'disabled'. With UM982 and a couple of rtk antenna, wich minimal configuration to obtain information on Message/Nmea/Hdt section?

Good afternoon. Thanks for the video. Can I transmit the correction signal from UM980 to UM982 via Sik radio?

Can I ask what made you choose Mode Rover Survey over UAV mode?
@oceanexplorationlab
@oceanexplorationlab Месяц назад
My “rover” was kept stationary hence survey mode gives better precision. For a more dynamic situation like a fast moving object, AUV mode is the appropriate setting.

In theory one could use this to create ground control points at a fraction of the cost of existing RTK bases and rovers correct? Would love an example of that workflow to see just how one would go about doing that.

By the end of this series, I hope to have all the pieces in place to accomplish that. You're absolutely right-using this setup, one could create ground control points at a fraction of the cost of existing RTK bases and rovers. Make sure to like and subscribe so you don't miss anything!
