1. Ensure that the Dock Server application is not running.
2. Connect the Dock Server machine to a Freewave transceiver, using the port specified
in compassCalibrator.conf and communicating with the glider containing the
compass to be calibrated
3. Log on to the Dock Server machine as user
localuser
and open a terminal window.
4. Go to directory /opt/locauser/bin and enter command ./calibratecompass
If no communication can be established with the compass, the application displays the following:
Compass calibration aborted: cannot communicate with compass.
In this case, as well as doublechecking the compassCalibrator.conf settings, check that the
glider is powered up and communicating over Freewave. Also, try power cycling the glider to
put the compass in
run
mode. If there is still no communication, make sure the glider is running
the
talk
utility by using the following steps:
1. Open a terminal window and start the minicom application on the specified port,
for example by entering: minicom u1 (where u1 refers to a minicom
configuration file, on the Dock Server machine, for port ttyUSB1)
2. Power the glider on. If in “boot app” then exit to PicoDos. If in “boot pico” then
leave in this state.
3. From the
(GPICO)C:\>
prompt, type
ver
(to display version information) and
then type
talk att
. This starts the
talk
utility and opens a serial port to the
attitude sensor. You should now see data being read from the compass.
4. Close the minicom application This frees up the serial port for use by the compass
calibrator.
5. Try starting the compass calibrator application again by going to directory
/opt/locauser/bin and entering command ./calibratecompass
Starting the compass calibrator in Windows
The compass calibrator application also runs in Windows using the following steps:
1. Using a serial port, connect a Windows machine to a Freewave transceiver
communicating with the glider containing the compass to be calibrated
