I recently installed a BerryGPS-IMU board on my Pi 4. Everything works great, gpsmon and cgps display serial port output without error.
I tested my setup out under a clear sky and I must have waited more than 15 minutes. There is no fix for the GPS. As I said, I use internal antenna, no external. Is this expected? How sensitive is the internal GPS?
Am I missing anything? The board was sitting out in the open air. Nothing to cover.July 15, 2022 at 11:54 am #17328richardpParticipant
Hi, if you are outside with clear access to sky, it should work.
Is the switch on the side in the correct position? it needs to be set to “int” for internalJuly 16, 2022 at 1:53 am #17329
Yes it switched to INT as we received it.July 18, 2022 at 4:17 pm #17331richardpParticipant
Can you please upload a photo of the BerryGPS-IMU board? I want to make sure it isn’t missing any chips. I am only interested in the top section where the GPS unit is (Green chip)July 19, 2022 at 2:01 am #17333
So after I got an external antenna and installed it, switched to EXT , the GPS is fixed with proper location. The accuracy rate is about +/- 10m (35′)
After that the GPS would locked with INT antenna as well later with the accuracy rate at about +/- 15m.
Is that the expected performance?
