The GPS module used a Patch Antenna made it very compact while still offering a -165 dBm sensitivity. The high sensitivity made it possible to detect the localisation signal even under bad conditions.
With the patch antenna already oriented to the sky, the module is ready to mount on the CanSat with a simple Grove cable!
=== Hot Start Localisation ===
What's make the difference of this GPS is its '''hot start capability'''.
What's make the difference of this GPS is its '''hot start capability'''.
Without the CR2032, the GPS module tries to locate the networks as it will do the very first time, this '''cold start''' may take up to 35 seconds (datasheet).
