GPS does not get a lock

Posted by Jaime Felipe on December 2, 2010 at 6:23pm
Hello,

My Mediatek GPS does not get a lock.
The blue led blinks slowly continuously. However, I don't think it's a voltage problem, since the voltage on the first pin of the module is 4.7, which I think is ok.

I have also tried to remove the battery, with no luck. 
The GPS is connect to the ArduPilot mega board and not to the IMU.
Everything else seams to work ok.

Chris, what else can I do??

Thanks
Jaime

    I found my mediatek would not lock if I had it sitting on top of my laptop. This leads me to think it is sensitive to electronic noise. Even outside with full sky it would not lock for hours. I had to move it two feet away and all was good in 30 seconds.

    If you've got one of the MediaTek's with the battery, remove the battery (just pry it out and throw it away--it's not needed) and try again.

    Also note that you have to reset APM once (warm start) after each cold start with the MediaTek. Troubleshooting.
