ESP32 based Local RTK Network

[@ivanopalka9253]

Thank you so much for another awesome video. I have been watching your RTK playlist and want to thank you for sharing your knowledge with us. You definitely got my wheels spinning thinking about the ideas where I could use this.

[@oceanexplorationlab]

Awesome, thank you!

[@mygps1]

Thank you for uploading very good information. It helps a lot in my work. Thank you.

[@oceanexplorationlab]

Glad it was helpful!

[@HeinzSeinz]

Super Videoserie! Hat mir sehr geholfen. Ich bin schon auf die Vermessung der Stationsantenne gespannt!

[@oceanexplorationlab]

Vielleicht wird das ein Weihnachtsgeschenk.

@@oceanexplorationlab jaaaa :) die unterschiedlichen Systeme WGS84 und ETRS89 machen mir Kopfzerbrechen...der UM980 kann nur WGS84, oder?

[@OloloSpirit]

Thank you very much, you really helped me set up UM980 as I need. There is an interesting topic - how about starting communication between the base and the rover using LoRa E32? I think it is very interesting.

[@oceanexplorationlab]

Yes, many people indicated an interest in using LoRa. It is on my to-do list. Thanks for the suggestion.

Olá amigo! É possível gravar os dados da base e enviar correções para rover usando rádio lora usando Esp32. De forma off-line ?

[@oceanexplorationlab]

I don't see why not. RTK bandwidth is low enough to allow for LoRa translated by ChatGPT to Portuguese: Não vejo por que não. A largura de banda do RTK é baixa o suficiente para permitir o uso de LoRa.

[@mottilein2010]

ChatGPT told me that it would be possible to set up an RTK base station in the garden and combine the correction signal with a RTK Correction provider (e.g RTKgo). Can you make a video on how to do that ? 🙏

[@oceanexplorationlab]

Maybe I am missing something, but I show how to send RTCM correction data to RTK2Go in the video series here: kzbin.info/www/bejne/gXi0YquarKakZ6M. Let me know if this is what you are looking for.

[@mottilein2010]

@@oceanexplorationlab basically I mean that one sets up ones own base station at home + uses an RTK signal from RTK2GO in addition, unes the average coordiantes of both

Very usefull video for sure !! One thing is, when you setup the Ntrip caster, you're basically creating a server that listens to a port(not to be confused with the Ntrip actual server like RTK2go), and requests to this caster is designed to come from the internet from rover clients or the like. So I guess you have you internet router configured with a port-forward to the caster IP/port, but you didn't mention this(so I'm just guessing that you do)... My question really is, how does this Ntrip Caster/Server/client differ from the Socket server/client... are Rovers requesting connection data, or are they more like multicasted and then the clients subscribe to that stream ? difference would maybe be that the Base station/caster would not see clients when in caster-mode, and it will in socket-mode ?? sry for this long comment.

[@oceanexplorationlab]

You are correct; the NTRIP Caster mode of the XBee is not a traditional NTRIP caster like RTK2Go. As I understand it, it differs from a socket server by filtering certain messages (e.g., GNGGA is only sent every 30 seconds) to save on bandwidth. It is useful if you want to stay within your local network (I don’t use port forwarding). If you want to receive your correction data via the internet, I would certainly use RTK2Go or similar.

[@jana171]

@@oceanexplorationlab Thanks for this VERY fast answer :-) Think I'm going to provide some RTK services using RTK2GO, because i think this is cool, but also mine some crypto, at the same time. But, Quick questions though : 1: as it seemed to me that you said the UM980 was best suited for Base-station applications, but will this UM980 chip work with the Ntrip Duo config ? 2: dependent on answer in Q1: If i get a UM982 to use Ntrip Duo configuration for dual operations (ONOCOY/RTK2GO), does this then also require a two antenna setup ?

[@oceanexplorationlab]

Yes, the UM980 will work with XBee-Duo. You are simply sending the same information to two NTRIP casters. There is no advantage to using the UM982 as a base-only disadvantages. Once you have your RTK2Go up and running, let me know the name of the mountpoint so I can include it in my list.

[@jana171]

@@oceanexplorationlab will do... now I will finally get to the ordering of the hardware... still have a long road to travel from here, but FUN !

[@jana171]

@@oceanexplorationlab I could only order the UM982(WITMOTION WTRTK GNSS GPS-RTK module UM982) from the trusted sellers on aliexpress, so I went with that, and also the ESP32 Wroom like in your BOM... I hope you get kickback from me using your link btw. Now all I can do is wait a month... hehe.

Update the files for esp32 s3 dev board

I tried and failed :-(
