SET USER DATUM
The GPS receiver has one user defined datum stored as ID number 50. The User
Datum command allows the user to define the constants used for a custom datum.
A datum is defined by a semi-major axis, an inverse flattening constant, and an
offset from the center of mass of the earth given as delta-X, delta-Y, and delta-Z
parameters.
Default values: WGS-84 parameters
