If a response message is not generated, recheck your cable connections and
communications parameters, and verify that the receiver is powered on.
Initialization
It is good practice to reset the receiver prior to operating it for the first time or if a
system malfunction occurs. A reset of the internal memory clears the memory and
restores the receiver to factory defaults.
To reset the receiver, send the receiver command: $PASHS,INI,5,5,5,5,3 <Enter>
Monitoring
Once the receiver has been powered on, connected to an antenna, and
communications established, commands may be issued to check the status of the
receiver and monitor receiver accuracy. The following examples serve as an
introduction to controlling the receiver. For a complete list of commands, see Chapter
6, Command/Response Formats.
Satellite Tracking
If you wish to monitor the satellites the receiver is tracking,
1.
Type: $PASHQ,STA and press <Enter> to query which satellites are locked
and their signal strength at the time the command is sent.
The response message typically might display:
This message indicates that the current UTC time is 18:38:31, the PRN # of
locked GPS satellites are 01 to 24 and the PRN # of GLONASS satellites are
33 to 56.
Position
If you wish to view the current position,
1.
Type: $PASHQ,POS and press <Enter> to query the position message.
The response message displays an ASCII string beginning with the header:
The message contains time, position, velocity, and DOP values. For further
description of the POS message, see "POS: Position Message" on page 162.
