ashtech DG16 - UTM: Universal Transverse Mercator (UTM) Coordinates

NMEA Commands 279
NMEA Commands
$PASHQ,UKO,[c1]
This command queries the UKOOA message, where c1 is the optional port
designator for the output of the response. If a port is not specified, the receiver
sends the response to the current port.
$GPUKO
The response is in the format:
$GPUKO,d1,d2,d3,f1,n(d4,d5,d6,d7,d8,d9)
where Table 8.52 outlines the response message.
UTM: Universal Transverse Mercator (UTM) Coordinates
$PASHS,NME,UTM,x,s,[f]
This command enables or disables the UTM message on port x, where x is the
output port, and y is ON or OFF, and f is the optional message output rate ranging
from 0.05 to 999 seconds depending on the measurement update rate option
installed.
The DG16 does not output this message unless it computes a position.
