GPS module
A GPS module UC530 from U-blox is mounted on the Koala. This
module is placed at the rear of the Robot, just above the battery
housing between the US sensors 8 & 9. To keep a good reception, do
not place metallic parts near the GPS antenna.
The module supports NMEA-0183 rev 3.01 communication protocol
and is configured at 115200bps.
The dsPIC of the Koala autonomously manages the main data
acquisition (number of satellites, latitude and longitude position, date
and hour, speed and altitude).
If you need more specific data, you can directly configure the GPS
module using the “X” command (see “NMEA_manual_for_Fastrax_
IT500_Series_GPS_receivers.pdf”
documentation
for
available
commands) and enable the transparent mode to get all the NEMA
commands sent by the GPS module (set auto mode bit 7, “A,128”
command).
The module is configured to return new data every second. If the user
enables the auto monitoring mode for the GPS (“A,64”), new data will
be printed every second.
Be careful, do not change baud rate of the GPS
module, as the dsPIC will then be unable to retrieve
data of the module. Do not change user parameters
too, as the number of writes is limited to 8.
