Anyone knows how this module (RM520N-GL) should be wired to the antennas?
It has 4 antenna pins.
I can buy something like this:
But none of this seems a “GPS antenna”, at least what I’m familiar with:
So do you have any ideas on how can I use this module for proper GPS positioning by adding a sophisticated antenna to it? (Possibly with a bit longer cable in order to place the antenna correctly).
VIM4 runs Android 14.
@danergo ,
Our board’s 5G module is like this.
Is it receiving gnss signal correctly? I.e. is google maps showing the correct location?
Thank you!
@william.lin can you confirm please? 
@danergo ,
Our SBC has currently only been tested with an external GPS module, and the GNSS functionality of the 5G module has not been debugged yet.
I am unsure whether the RM520N-GL module has integrated GNSS functionality. If it does, you can make the following modifications based on the documentation.
After these modifications, it will be possible to obtain GPS data through the native interface, which will also achieve your goal.

The RM520N-GL 's built in GPS module does work on the VIM4 but it is a bit odd and might not be suitable for your use.
If you look at the RM520 data sheet you’ll see that the antenna connectors are all multi purpose, often a mix of Hiband and Lowband 4g and 5g and GPS - you need all 4 connected to a good multi wavelength passive antenna.
