PPS output of the GNSS Receiver

development
1

Hi all.

I would have loved to have an output from the receiver in the brain that can give Pulse Per Signal(PPS) to sync other sources of data that are outside of the Brain. Like right now, I am in a situation where I have a ROS2 runtime with sensor topics that could benefit from PPS when it comes to syncing them but it seems like to achieve this, I’d have to get another receiver. Or is there a way/hack that I can still obtain the PPS signal integrated with the brain?

Hi @andykibz

Have you tried using the GPS topics itself? While farmng-amiga.service is not synchronous, we do tightly integrate the GPS topics to a synchornizer, so you should see all the GPS topics (pvt, relposned, and ecef) very close to 2.5 Hz.
