40 Z-Family Technical Reference Manual
Send the following commands to the receiver. The receiver accepts RTCM RTK data
in message types 18 (Carrier phase data) and 19 (Code phase data), 20 (carrier phase
corrections) and 21 (code phase corrections), 3 and 22 (Base station position).
Make sure to issue command $PASHS,RTC,REM,c before the $PASHS,CPD,MOD,ROV command.
Doing so in reverse order disables the CPD mode.
The receiver is set up as a RTK remote station. Turn on the GGA, GLL, or POS
message to obtain position. PBN does not provide RTK position, only stand-alone or
code differential.
RTK (Real Time Kinematic) and CPD (Carrier Phase Differential) are synonyms.
Using Ashtech DBN Messages
You must have the [J] option installed on your receiver.
Send the commands listed in Table 3.13.
The receiver automatically detects which port is receiving the DBN messages and
uses them in the RTK solution.
