Hi,
I walk through datasheets of the different GPS modules, and I have some questions :
- velocicy/speed provided in the NMEA messages are they always doppler speed, or can they be for some modules derived from positions ?
- some modules claim a 0,1 m/s velocity accuracy, but some others do not give any information (locosys, SIRF...). Are all modules equal on this topic, or can we encounter different performances there ?
Regards,
JMF
