RxControl: Navigation > Receiver Operation > Position > Datum
Use these commands to define datum transformation parameters from the global
WGS84/ITRF datum to the user datum identified by the first argument.
The receiver applies the linearized form of the Helmert similarity transformation. The coor-
dinates in WGS84/ITRF are transformed to the user datum using the following formula:

IERS Conventions (2010), Technical Note No. 36.
The time derivative of the transformation parameters can be specified with the command
For the receiver to apply the transformation parameters, the corresponding user datum must
be selected in the
command.
