This log reports the datum transformations known to the receiver. This includes the default transformations included in the firmware, plus user-defined transformations entered using the DATUMTRANSFORMATION command.
The entry “USER” to “WGS84” transformation in this log is the datum transformation set by the USERDATUM command or the USEREXPDATUM command. The parameters in this entry will differ from those entered via the user datum commands due to differences in units and convention.
