I have run my Kiwi for quite a while without a GPS antenna, so I'm new to the party so to speak. I purchased a generic automotive "puck" style antenna with an SMA connector, with ~28-30 dB of gain.
After several hours of operations and a couple of reboots/restarts, I see that it never appears to "lock" to any of the GPS satellites, despite typically showing 3-4 in view and as many as 8 at once, but apparently at signal levels too low to decode.
After trolling through the archives, I gather that the GPS receiver is less than ideal and needs good conditions to work. I never see a SNR value more than about 20 dB. My antenna is on a metal plate near an east-facing window.
Are there any diagnostics to determine whether the system is working correctly, or do I need a 40 dB gain antenna or a northerly exposure?
Thanks es 73,
