The following commands are supported; refer to the individual commands in the section
Sapphire Input Commands Detailed Formats in this manual for details, as necessary:
[EXTRAPBASE]
This command is used to enable the MBRTK rover to extrapolate base motion or lack thereof.
The receiver must be running in MBRTK rover mode for this command to take effect. This
feature is defaulted to Off and generally provides the best performance in this mode.
[FIXBASELINE]
This command is used to enter baseline mode and length information for the MBRTK rover. Use
the equation 0.6/L (whre L is length in meters) degree as a rough 1-sigma estimate of heading
accuracy. The minimum antenna separation is 1m. For heading applications, no maximum is
given. MBRTK operation is possible up to a 40km baseline length with the same degredation in
positioning performance accuracy as normal RTK over the same baseline length.
[ANTALIGN]
This command is used to enter baseline installation information (orientation) for the MBRTK
rover.
[ARLENGTHCONSTR]
This command is used to specify whether or not the baseline length is to be used as the
ambiguity constraint and pseudo measurement. To obtain a valid setting, the receiver must be
in MBRTK rover mode and the fixed baseline must be set.
[INCLINECONSTR]
This command is used to set the maximum allowed inclination angle for the MBRTK rover.
General Setup Commands
These commands are related to general setup, but are self-explanatory; refer to the individual
commands in the section Sapphire Input Commands Detailed Formats in this manual for details,
as necessary:
[RTKTIMEOUT]
[RTKMULTIPATH]
[RTKFIXMODE]
[RTKSYNCMODE]
[RTKFLOATTIMEOUT]
[DYNAMICS]
This command is used for specifying receiver dynamics. The setting affects the RTK rover
dynamic, the RTG dynamic, and the velocity smoothing settings.
Dynamic_mode is the receiver overall dynamic setting. When a user specifies
dynamic_mode as STATIC, LOW, MEDIUM, or HIGH, the receiver will use the
