Tips and questions relating to the GPS modules from SFE
By shocktech

i purchased EM-406A GPS module last week and i've been trying to get a fixed position ever since then. i am using with GPS Eval with usb and ac power adopter.

i was searching all the forums and did try every possible method out there such as separte power beside of USB and worm, hot, or cold restart. and even waited for more than 2 hours to get the fixed positions.
NO LUCK!!! did try in the morning, afternoon, and night.

Does the module have a clear view of the sky?

Can you post the GPGSV sentences? That'll tell you which satellites the module can see.
