GPS module can't find satellites

Post by baruchli »

I had purchased and assembled GPS logger shield together with EM406A module. Now I am testing it with FTDI cable and after about 10 minutes of running I got the next output:
$GPGGA,001227.035,,,,,0,00,,,M,0.0,M,,0000*56
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPRMC,001227.035,V,,,,,,,150209,,,N*42
$GPGGA,001228.035,,,,,0,00,,,M,0.0,M,,0000*59
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPRMC,001228.035,V,,,,,,,150209,,,N*4D
$GPGGA,001229.035,,,,,0,00,,,M,0.0,M,,0000*58
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPRMC,001229.035,V,,,,,,,150209,,,N*4C
$GPGGA,001230.035,,,,,0,00,,,M,0.0,M,,0000*50
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,1,1,00*79
which is to my best understanding means EM406A module find 0 satellites (see GPSV info). The environment is indoors but pretty open for communication.
The question is: "Does some error in shield assembly may prevent GPS module from correct communication with satellites?

If you are communicating, the shield/module interface is working properly. Shield assembly shouldn't affect satellite reception. Does it work better outside or close to a window?

That's was a solution: We just took the device outdoor and then it found satellites.

Thank you for suggestion!
