First notices about the use of Ublox GPS receiver

Post by Mitteau »

Hi
1/ not surprinsigly, the fix takes a lot of time. 12.5 minutes for the last one. This needs roughly 30% of the battery,
2/ this means that we must implement some way to save (on the client's machine?) the ephemeris of the satellites at the shut down to get further hot fix,
3/ close to the board the receiver is too perturbed,
4/ the fix was obtained with the receiver at 2-3 cm of the cf board,
5/ running the motors do not affect the receiver,
6/ walking in my garden is clearly visible on the datas,
7/ hdop of the fixings are good (around 2.9),
8/ to know the position of the cf needs probably some kind of flitering.

These comments are provisional, for instance concerning the running of the motors.

Next step is to finish a useful tab for GPS data.

Best regards

Hi,
Do you have a Github project about the use of the GPS?
