differential corrections are only available in regions of the world where
such correctional data is broadcast. The currently operational systems
referenced are WAAS (USA) and EGNOS (Europe). As future SBAS
systems come on line the receiver may need firmware updates to allow
for the correction.
RS-232 Serial Output
Standard NMEA-0183 message strings GPGGA and GPRMC are
sent out by default at a baud rate of 57,600. The baud rate and type of
messages can only be changed prior to sale or by sending the unit back
to MoTeC USA, Inc. on an RMA with the requested changes stated.
CAN Output
The RaceGrade GPS version 3 receive includes a CAN output.
The CAN bus speed operates at 1 mbit/s and on the base ID of 0x146.
The CAN output is based off the MoTeC GPS with STC (serial to CAN)
which mimics the NMEA0183 serial packet transmission. Simply select
the “GPS Async” template for MoTeC devices. A limited number of
alternate baud rate and message address can be requested if the
standard is not suitable for your application. They can only be changed
prior to sale or by sending the unit back to MoTeC USA, Inc. on an
RMA with the requested changes stated.
