F ....................................................... MBRTK Commands and Responses
Setting Up the Moving Base Position
The position of the moving base is set up via the [RTKMODE] command. Refer to [RTKMODE]
in this manual for further instructions.

When the rover is operating in MBRTK, PVT1B is not impacted. PVT1B operates in
the mode based on the input correction format. In other words, if StarFire
corrections are being received, PVT1B will be in StarFire (5cm) operation and
MBRTK1B (with corrections from a moving base) will be at RTK levels.
[RTKMODE]
Examples:
[RTKMODE]BASE5E,,,1,DYNAMIC
Configures the receiver as an NCT moving base RTK base and output corrections
on port 1
[RTKMODE]ROVER,NCT,,,DYNAMIC
Configures the receiver as an NCT moving base RTK rover
Do not use the following configurations:
BaseRTCM1001 Receiver operates as an RTCM 3.0 type 1001 base station
BaseRTCM1002 Receiver operates as an RTCM 3.0 type 1002 base station
