Raw Data Commands
The raw data commands cover all query and set commands related to measurement,
ephemeris, and almanac data.
Set Commands
There is only one set command that controls the continuous output of all raw data
messages: the $PASHS,RAW command. The $PASHS,RAW command allows you
to enable or disable the output of raw data messages and to set the port to which the
messages will be output. The general format of the $PASHS,RAW command is:
where str is a 3 character string that denotes the different raw data output types, c is
the output serial port, and x is the ON/OFF toggle. For example, the command:
will output MCA messages to serial port A. IF the $PASHS,RAW command is sent
correctly, the receiver will respond with $PASHR,ACK acknowledgment. The
message will be output to the indicated serial port at the recording interval defined by
the $PASHS,RCI command. The default output frequency is every 20 seconds.
Raw data messages are disabled by sending the $PASHS,RAW command with ON/
OFF toggle field set to OFF. Multiple messages may be disabled from a particular
port by sending the $PASHS,RAW command with ALL in the string field.
For example the command:
disables all raw data messages from port B. To see what raw data messages have been
enabled, use the $PASHQ,RAW query.
In general, the parameters that affect raw data output are the same as those that
control data recording including: recording interval, elevation mask, and minimum
number of satellites. See Table 6.33, Raw Data Commands for more details about the
commands that control these parameters.
