Page 4: Introduction
RaceGrade Page Introduction RaceGrade Thank you for purchasing a GPS receiver. This user’s RaceGrade guide was written to help you understand how the (Global Positioning System) device works. Please read it thoroughly. Installation is very important, and understanding how GPS works will help you get the most from this sensor. -
Page 5: Warm Up Time
RaceGrade Page Warm Up Time When the GPS receiver is first powered, it will start searching for satellites to lock onto. This process takes time. It will take longer the first time you power up at a new location from where you had previously turned it off. -
Page 6: 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 be changed by sending the unit back to RaceGrade. CAN Output The RaceGrade GPS version 2 receive now includes a CAN output. -
Page 7: Installation
RaceGrade Notes Installation GPS Receiver The enclosure is made from 6061 Aluminum alloy. It should be mounted in a safe location, away from electrical noise, vibration and temperature. Maximum operating temperature is 70°C or 158°F. NOTE: To counter any possible vibration damage, please mount the receiver box on soft Velcro, not the hard industrial type or even double sided foam tape. -
Page 8: Loss Of Signal
RaceGrade Notes decrease slightly. Keep this in mind when mounting on a motorcycle as the bike leans from corner to corner. Try to keep the antenna mounted on the centerline of the • vehicle. As with normal wheel speeds, during cornering the speed of the inner side of the chassis is less than the speed of the outer side of the chassis. -

6 or 7 is decent but may suffer some noise. Values below 6 will have very poor accuracy. For the RaceGrade GPS, the number of satellites does not include the SBAS or WAAS DGPS satellites. So a value of 10 is the maximum possible even though the unit is capable of tracking 12 satellites. -
Page 10: I2" Analysis Math
RaceGrade Notes “i2” Analysis Math GPS data will have an inherent time lag. The sequence of delays are from receiving real-time satellite signals, processing them, sending the data into the logger and the logger logging them. MoTeC’s “i2” has a built-in “Corrected GPS” function found under the “Tools” pull down menu. -
