Set Command Library
VEC: Vector Output Mode
Function
This command is used to define the output mode for vector
(baseline) estimates. Changing this parameter will affect all
the messages providing baseline-related information, but not
those providing position information such as POS and GGA
(the output of which is controlled by the CPD,FST command).
Command Format
Syntax
$PASHS,VEC,s1[*cc]
Parameters
Comments
• With Fast output mode selected (s1=FST), the rover
receiver can provide a baseline solution at every receiver
epoch. Usually, this mode delivers estimates of lesser
quality compared to TT. However, they are available at
regular intervals of time and with minimum latency.
• With time-tagged output mode selected (s1=TT), the rover
receiver can provide a baseline solution only at epochs to
which incoming reference (corrections) data are tagged.
This mode delivers the best possible estimates in terms of
accuracy. Estimates may however be affected if the data
link experiences delays or outages.
Example
Enabling Fast output mode:
$PASHS,VEC,FST*48
WAK: Acknowledging Alarms
Function
This command is used to acknowledge all alarms. This will
also turn off the beeper (if previously set to beep on
