accel altvalidmax m

Set the maximum allowable change in altitude in metres over a period of one second. If this threshold is exceeded, GPS module will be reset.

m = 0	Disable checking this
m = 1 to 1000	Change in altitude in metres (Default 108)

Notes:

Default of 108 corresponds to a vehicle travelling at 150 km/h on a 15 degree incline
This check is ignored if GPS speed is within range of OBD speed, configured via cmd accel gpsobddiff

Examples:

Set the maximum allowable change in altitude to 86 metres over a period of one second (corresponds with 120 km/h @ 15 degree incline) :
cmd accel altvalidmax 86
