Problems I'm having with the GPS
Username Checked outside? External antenna? Note
Pthorin Yes No I tried for about 40 minutes outside, I'm running om-gta02 P1-Snapshot-20080622. Did get GPS time outside, but only got lines like:

$GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30

--Pthorin 05:11, 11 July 2008 (UTC) I tried it out once again after removing the front cover and got a fix quite fast, less than five minutes. Could there be an issue with the case blocking the signals? Could the snap/latch above the antenna be a problem?

iandouglas Yes No Spent over a half hour outdoors, the NMEA port on my Samsung Blackjack 2 found my position just fine, but also got the same 99.99,99.99,99.99*30 line as Pthorin when powering on the GPS unit, starting gpsd, then running gpspipe at the command line
Dummy ?  ?

Solved problems

Let's collect hints which could solve the above problems here. E.g.: How to get the best results with your internal antenna

  • Before reporting a problem here, please check that you've had the GPS out in the open air, preferably with the GPS antenna pointed up, for over 15 mins. (the screen the right way up). This should get a lock in even the worst cases.
  • Also note if you've tried unpluging and repluging the internal GPS connector. (See Disassembling_Neo1973 about 2/3 of the way down. (this may differ on freerunner, pictures appreciated)

FreeRunner_GPS_antenna_repair_SOP Indicates that the problem may be bad soldering, and includes a guide to fix. This will presumably void your warranty.
