Transmitting the CanSat localisation while the parachute descent will, for sure, help you to find on the ground!
The CanSat GPS module use the GPS / GALILEO / GLONASS / QZSS satellite networks to calculate the current position.

The GPS module used a Patch Antenna made it very compact while still offering a -165 dBm sensitivity. Already oriented to the sky, the module is ready to mount on the CanSat with a simple Grove cable!
What's make the difference of this GPS is its '''hot start capability'''.
The '''Hot Start''' requires a CR2032 coin cell to be inserted. Then the GPS module keeps an accurate time tracking making it possible to get satellite '''fix within 1 second'''!
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).
