FST: Fast CPD Mode

$PASHS,CPD,FST,s
Enables/disables fast CPD mode, where s is either ON or OFF. If this mode is set to
ON, the rover receiver provides a fast CPD position solution. This command is
relevant for ROVER receiver only. The default is ON.
Fast CPD ON means faster update rates, lower latency (typically 50-100 ms), and
lower accuracy (typically about 2 cm horizontal 95% (i. e. 2RMS) confidence
accuracy).
Fast CPD OFF means lower update rates limited to the rate at which corrections are
received from the base; Position latency is approximately equal to the interval
between position updates plus a delta; Accuracy is higher (typically about 1 cm
horizontal 95% (i.e. 2RMS confidence accuracy).
Example: Turn fast CPD OFF
INF: CPD Information
$PASHQ,CPD,INF,c
This command queries the INF message where c is the optional output port. This mes-
sage contains base and rover satellite status information.
Example: Query the CPD satellite information message to the current port.
$PASHR,CPD,INF
The response message is in the form:
Command/Response Formats

Satellite 18, warning = none
Satellite 19, warning = L1 measurement warning
Satellite 34, warning = none
Satellite 44, warning = none
