MoTeC Using the GPS 1
Using the GPS
Description
The GPS-G1 is a 5 Hz GPS that is suitable for the high dynamics of motor
sport applications and is compatible with Motec ADL2, SDL & ACL logging
devices.
The standard GPS-G1 unit operates at a baud rate of 19200, while the GPS-
G1(T) version operates at a baud rate of 38400.
The GPS-G1 consists of a GPS unit with a built in antenna.
The units provide speed and position information, as well as altitude, heading,
date, time and GPS statistics.
The speed information can be used for display and logging purposes avoiding
the need for wheel speed sensors.
The position information can be used in the i2 data analysis software to create
track maps and to show and compare the driven lines.
Throughout this manual both the standard GPS-G1 version and the GPS-
G1(T) version will be referred to as GPS-G1 except where details specific to a
particular model are discussed.
Mounting
The GPS unit has an integrated antenna and should be mounted on an
external horizontal surface that has a clear view of the sky.
The unit should be mounted away from sources of interference including
other antennas.
If mounting on a non metallic surface it may be necessary to add a metallic
ground plane under the unit to improve the signal level. The ground plane
should be at least 150 mm (6 in) square and may be made of aluminium or
steel.
The unit has a magnetic mounting base and includes an M3 thread in the
centre.
