MoTeC Using the GPS 1
Using the GPS
Description
The GPS-L5 is a 5 Hz GPS unit, set at a fixed baud rate of 19200 and is
preconfigured to suit MoTeC ‘Hundred Series’ and M84 ECUs.
The GPS-L10 is a 10 Hz GPS unit suitable for use only with MoTeC
Dash/Data Loggers (excluding original ADLs). It is configured at a fixed baud
rate of 38400.
Both are suitable for the high dynamics of motor sport applications. The units
have a built in antenna and provide speed and position information, as well as
altitude, heading, date, time and GPS statistics.
In circuit racing, a GPS unit can be a cost effective alternative to the
traditional lap timing system. When using a MoTeC Dash/Data Logger, the
position of the start/finish line can be marked either by a push button operated
by the driver when passing the line or by entering the coordinates directly into
the data acquisition system. This position can then be used by the Dash/Data
Logger as a beacon to calculate the lap time and by the data analysis
software to indicate the start of each lap.
The speed information can be used for display and logging purposes,
eliminating the need for wheel speed sensors. This is particularly useful for
marine applications as there are no wheel speeds available.
GPS position information can be used in MoTeC's i2 data analysis software to
show and compare the driven lines and to create track maps. The driven lines
can also be plotted over a Google Earth image, allowing circuit racers and
rally drivers to see the path travelled in a real life context.
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.
