BESTDATUMINFO

Datum information for best position

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

This log reports the datum and co-ordinate epoch of the solution in the BESTPOS log. For differential solutions, such as RTK or PSRDIFF, where the base station datum is not known, “UNKNOWN” is reported with an ESPG code of 0. Single-point and SBAS report “ECEF” and code 0.

Message ID: 2305

Transformation Status

Binary	ASCII	Description
0	GOOD	An exact transformation was found and used.
1	ECEF_EQUIVALENCY	An exact transformation could not be found, but a similar transformation involving another Earth-fixed transformation was found and used.
2	SERVICE_DETAILS_UNKNOWN	The datum of the input solution was not known and therefore a transformation could not take place.
3	REQUESTED_TRANSFORMATION_UNAVAILABLE	No transformation could be found to transform the solution into the requested datum.
