CT2: Combined Measurement/Position Data (Format 2)

$PASHS,RAW,CT2,c1,s2,[f1]
This command enables or disables the combined measurement and position data
message format 2, where c1 is port A, B or C (optional port), s2 is ON or OFF, and
f1 is the optional numeric output interval setting supporting a range of 0.05 to 999
seconds, depending on the measurement update rate option installed.
$PASHQ,CT2,[c1]
This command queries for a combined raw data message in the CT2 data structure.
This message contains elements derived from the MCA and PBN messages.
c1 is the optional port designator for the response. If a port is not specified, the
receiver sends the response to the current port.
$PASHR,CT2
This message is not output unless the receiver is tracking at least one satellite. The
CT2 message contains an adjusted receive time (the time at which the data was
received) with satellite PRN numbers and channel assignments in association with
full carrier phase measurements and smoothed pseudo ranges. This message
