cool

None. Also, this is the only one I tested, so no suggestions otherwise.

It sounds like an exciting project. I have no current plans to create a video about waypoints, but ArduPilot is a tool you want to look into.

Welcome!

Certainly, you can use the UDP/TCP socket functionality of the XBee for that purpose. I intend to publish a video on this topic shortly.

@@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.

Thanks, have fun

Once I figure it out, I plan to make a video on it.

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.

@@oceanexplorationlab RectoryFarm is 26km away from my location in a straight line.

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.

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.

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.

Thank you, I'm glad you found what you were looking for.

@@oceanexplorationlab I hope you have more tutorials on creating libraries

Fantastic! I try to make this as noob-friendly as possible. Let me know if you get stuck.

@@oceanexplorationlab Stuck - no power on esp32 unsure what the 3v3 is suppose to be connected to? No red power light when the um980 is connected to laptop. I must have something wrong on the breadboard.

​@@whiskerrub3821 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.

@@oceanexplorationlab Ok so try omitting the LEDS? I was unsure how you connected the wires beneath the esp32, definitely I have a lot to learn.

@@whiskerrub3821 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.

Have fun!

Can you tell exactly what devices you purchased and how much you spent?

@@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.

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.

It sure is. It is a simple UART.

this is the commands launched freset config signalgroup 2 mode base 60 2 2 5 GNGSV 1 unlog rtcm1005 30 rtcm1033 30 rtcm1077 1 rtcm1087 1 rtcm1097 1 rtcm1127 1 saveconfig

i try don't use unlog but the satellite map not working!

you may be missing the GNGGA 1 command

@@oceanexplorationlab thanks

next send:MODE BASE TIME 60 the message is disappeared

mode base 60 2 2 5 is wrong conf! the correct conf is: mode base time 60 2 2.5

i want more of 2m of precision is possible put 1mm? like mode base time 60 0.001 2.5

I believe there is a misunderstanding regarding the command. In the command: `mode base time 60 2 2.5`: `60` is the time in seconds that all fixes obtained by the UM982 must remain within an area of horizontal and vertical precision. `2` is the horizontal precision in meters that all fixes must meet to declare the survey complete. `2.5` is the vertical precision required for all fixes to complete the survey. If the previously saved position is within these ranges, the station coordinates stored in flash memory will be used; otherwise, the position in flash memory will be updated. By the way, a 1mm precision in positioning is unrealistic.

@@oceanexplorationlab why is centimetric precision? in the datasheet tell of 0.8cm

typo! UNLOG not UNIOG

are you using UM982?

coming soon

Welcome!

coming soon

I don't see why not

@@oceanexplorationlab thank you. I'll try

That is high praise. Thank you!

I'm glad to hear the referencing part worked well for you. However, I'm not entirely sure what you mean by "VTR." Could you provide more details? I'll pin this comment to the top so that someone else might be able to provide a solution. Thanks for your feedback!

@@oceanexplorationlab FIRST of all, my TYPO. The correct check-box is VRT (and not vtr). My bad!! It is a click box on the top right side of the SAVE RASTER LAYER AS , beside the format (GeoTiff), a tick-box that reads "Create VRT"; and it is responsible for creating the .worldfile definition so that the saved image can be recognised as geotiff and open on the right spot inside a CAD, GIS, etc program

it seems to be a general issue with lots os users being unable to save GeoTiffs in QGIS. I currently usa SAGA GIS to save the GeoTiFFs because I cannot do it inside QGIS. I have tried every tutorial including ones with "custom" save file options , such as tweaking compression, creating .wtf company file etc

By 'OS,' do you mean macOS? In other words, are you running QGIS on a Mac?

@@oceanexplorationlab No. Windows in my case.

Good question, I have been wondering myself. I reached out to wit-motion regarding firmware upgrades. I will let you know once I hear back.

Turns out you must request the firmware from Witmotion and provide proof of purchase.

@@oceanexplorationlab What is your firmware version?

@@oceanexplorationlab I have the UM982_R4.10 version for this receiver. WitMotion has provided me with it to ensure that the module wasn't faulty.

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.

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/

@@oceanexplorationlab Very good link. Thank You.

Glad it was helpful!

that's still the plan

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!

Welcome!

Great to hear! I hope to have the Rover video up over the weekend. Let me know how it goes.

You're welcome!

Glad it was helpful!

108 / 5,000 I haven't figured out the PPP myself jet. But when I do I plan to make a tutorial. Thanks for the suggestion

At the beginning of the summer, firmware for the um980 was released, which has this feature. The activation command is in the instructions for the modules.

Cool. I'm working on the next video right now. Let me know when/if you start your setup and how it goes.

Awesome! Thank you!

Thanks for the comment

Glad you enjoyed it

Absolutely, by the end of the series, I hope to have provided step-by-step instructions on how to build and set up the base/rover RTK solution. The module I am using is an L1/L2/L5 triple-band system. I'm not sure what your $15k setup adds to this and what your requirements are. The video on how to set up the base should be out next week. Let me know if you decide to follow along. Cheers!

Working on it!

Awesome, thank you!

Glad it was helpful!

Thanks, it's good to know it still works with new visions

Thanks for that!
