Communication between the base station and rover

Good day,

I am a student and working on a project, I am currently researching how to use the GPS-RTK2. I want to build my own base station for RTCM correction data and let the base station transmit that data to the rover. I would like some help on how to communicate between the base and rover , currently looking into LTE and bluetooth, do you have any suggestions for devices that is compatible with the GPS-RTK2 for communication. ?

  1. The module or board has several interface, cant i just communicate directly between the boards using the interface ?

Thanks in advance.

Hi,

Have you reviewed the GPS-RTK2 hookup guide yet?

https://learn.sparkfun.com/tutorials/gp … -guide/all

It provides detailed information on how to connect to a RTCM correction source and pipe the data over Bluetooth. I think it should be exactly what you’re looking for.

Cheers,

Adam

Thank you for your reply,

Yes I have read the guide, but i am not quite sure because i need an NTRIP caster, If i use Ucenter i would not need to configure and other devices to make it a caster ?, would Ucenter just waork as a caster ?

Thank you

Hi,

If you look in the Hardware Overview section of the GPS-RTK2 hookup guide, you’ll see that it says:

If you’ve got the ZED-F9P setup for base station mode (also called survey-in mode) the UART2 will output RTCM3 correction data. This means you can connect a radio or wired link to UART2 and the board will automatically send just RTCM bytes over the link (no NMEA data taking up bandwidth).

This seems like the best way to get RTCM data from your base without having to worry about connecting to a correction source. Keep in mind the SparkFun Bluetooth Mate Gold has a range of only 100 m, so if you’re going to be sending RTCM corrections to a rover (drone) that’s further away, you’ll likely need to use a different radio.

Cheers,
