Is there any GPS parameter that can tell that RF frontend of GPS has some issues or you concluded it after seeing no. of sats going to 0?Thanks.
Zero sats is a very telltale sign.
Thanks.Will report back after rewiring my GPS.
Finally solved my issue!! Thanks everyone for your suggestions.
I did two things.First i reset my GPS to default by using Ucentre software.That made a big difference in GPA delta.Now i don’t see anything above 0.2 sec.
Second i wired my GPS from a dedicated clean 5v power and that fixed my no. of sats.Now i don’t see no. of sats dropping to 0 anymore.
