Commands
$PASHQ,UTM,[c]
This command allows you to query the UTM message, where c 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.
$PASHR,UTM
This message is not output unless positions are being computed. The UTM
message contains position rendered in UTM coordinates, plus UTC time, the
number of satellites used to compute the position, the mode of the position fix (i.e.,
autonomous or corrected), and more. The message is output in the format:
$PASHR,UTM,m1,m2,f3,f4,d5,d6,f7,f8,c9,f10,c11,d12,s13*hh
Table 4.111 defines the message format.
