Racelogic Antenna Options

Your choice of antenna is critical to the accuracy of measurement.

Racelogic provide a number of different antenna options, depending upon the measurement system, the type of vehicle being used and the surrounding conditions.

Why use different antennas?

Standard magnetic “patch” antennas are suitable where they have an unrestricted view of the sky and a good metallic ground plane, such as a car roof.

However, the quality of the signal received can be reduced by reflections from surrounding buildings, trees, and other obstructions. This is known as multipath and can result in increased noise and reduced accuracy.

Further effects of noisy GPS signals

• Less accurate general performance results. If the vehicle test is using speed as a start or end condition then the test could be started or stopped at the wrong time, leading to incorrect results

• Less accurate Lateral and Longitudinal acceleration data • Less accurate Radius Of Turn and Centre Line Deviation tests • Less accurate slip angle tests • Less accurate vehicle position / driveline

An RLACS171 Dual Antenna Mounting Pole (max. width 2.5m) ensures the most accurate attitude measurement.

RLVBACS067

GPS/GLONASS ground plane antenna with mounting plate

VBOX unit with RTK Used to track GPS and GLONASS satellites.

RLVBACS068

GPS/GLONASS ground plane antenna

Base Station Used to track GPS and GLONASS satellites with an RTK and GLONASS enabled DGPS Base Station.

Typical antenna placement

As a guide, the following should be observed when determining the best place to locate your antenna:

• Car: On the roof away from other antennas and any roof bars • Car (no roof): On the highest point of the boot • Motorbike: At the rear as far away as possible from the rider • Truck: Behind the cabin or on the trailer • Other vehicles: Away from metal obstructions and as high as possible

For any GPS antenna, the best signal will be received with the clearest view of the sky.
