BESTUTM

Best available UTM data

Platform:

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

This log contains the best available position computed by the receiver in UTM coordinates.

See also the UTMZONE command and the BESTPOS log.

The latitude limits of the UTM System are 80°S to 84°N. If your position is outside this range, the BESTUTM log outputs a northing, easting and height of 0.0, along with a zone letter of ‘*’and a zone number of 0, to indicate that the data in the log is unusable.

Message ID: 726
