Hello,
I have a problem with GPS module, which after 2-3 minutes (from the time when the position is found) stops “updating” the position (even time in Debug window stays the same)
Looking closer at the problem, using NMEA sentence following output appears in debug window:

for the first 2-3 minutes output is fine- accurate position etc
however, after this time GPS starts to print strange statements, which are no longer parsed:

i.e. prints RMC statement in the same line as GGA,
what is more some of the statements are cut in the middle:

I used Spider mainboard
I used the code from GHI website (the simplest one with GPS only)
I tried different firmwares (most recent ones)
I tried USB and 9V battery to power mainboard
I followed all the “official” instructions
I tried 3 different GPS modules- all show the same problem
I tried different sockets
I followed all the instructions and everything should work fine. Is it possible that there is something wrong besides hardware?
