The GPS receiver is in navigation mode upon power-up, with 1PPS output free running. After 3
minutes of valid position fix and remaining under static-mode, the receiver changes to timing-
mode, with 1PPS output signal synchronized to the UTC second. The receiver will change to
navigation-mode, with 1PPS output free running, if the receiver is in motion. The 1PPS output
will become synchronized to the UTC second again after the receiver had remained in static
mode for 3 minutes.
2.9 Antenna
A numbers of important properties of GNSS antennas affect functionality and performance,
including;
Frequency coverage
Gain pattern
Circular polarization
Multipath suppression
Phase Center
Impact on receiver sensitivity
Interference handling
The GPS610F module is designed to work both active and passive antenna. Active antenna
with gain in range of 10 ~ 30dB and noise figure less than 2dB can be used.
