2.2.5 AT+UBXCFGDPM – Display / Set GPS module Dynamic Platform Model

This command will display or set the Dynamic Platform Model used by the GPS module thus adjusting the
navigation engine to the expected environment. This can result in a better interpretation of the
measurements and hence more accurate position output.

Syntax: AT+UBXCFGPM=<n>

<n>

1 Stationary – Velocity is constrained to 0 m/s
2 Pedestrian – Assuming low accelerations, portable devices moved by manpower
3 Automotive – Assuming low vertical acceleration, passenger car dynamics
4 Sea – Zero vertical velocity, applications at sea
5 Airborne <1g – Dynamic range greater than car and greater vertical acceleration
6 Airborne <2g – Typical airplane environment
7 Airborne <4g – Extreme dynamic environment
