I power on the GPS module (NEO-7M) in the outdoor over 10 minuites.
I check the location of U-blox/ u-center is same with Google map.
And then, I check the location of the com port but it different with u-center tool.
Does the u-cneter have other transfer for the NMEA data??
Google MAP: 24.777489881299978, 121.00047452009582
U-center: 24.77746233, 121.00050867
com-port(NMEA): 24.4664351, 121.0003230
