I have bought uBlox M8T from CSG Shop (http://www.csgshop.com/product.php?id_product=205
) and i'm using Sparkfun antenna VTGPSIA-3 (https://www.sparkfun.com/datasheets/GPS/embeddedsma.pdf
). I took laptop to my car and after few rides I see 3 problems:
1) Very low accuracy - sometimes error is about 10-15m
2) No fix when driving > 50km/h
3) I cannot convert my files from .ubx to RINEX using rtkconv
What could be a problem? How can I fix it?
I tried to change frequency, only GPS, GPS+GLONASS, SBAS. RAW messages are enabled (I can see it in RAWX tab). I'm using Windows 10 so I had to remove Sensor API driver and use COM port to be able to pull GPS config.
