Antennas and Antenna Mounts

Posted in Accessories

Overview

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

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.

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

Ground Plane Antennas

Ground plane antennas give best protection against multipath reflection. They are used when a suitable ground plane is not present and are ideal for high accuracy position work, marine and mining applications.

Mounts

Antenna Mounts

Racelogic offer multiple antenna mounting options for all types of vehicle roof materials and antenna separation and IMU mount requirements.

RLACS223 suction roof mount

Roof Suction Mount (RLACS223)

This vacuum suction mount allows for a magnetic antenna to be used on vehicles without a metal roof, e.g. vehicles with an aluminium chassis, glass roofs or carbon fibre bodywork.

 RLACS159 with antenna

Roof Mount for Ground Plane Antennas (RLACS159)

This vacuum suction mount allows for a ground plane antenna (e.g. RLVBACS067) to be used on vehicles without a metal roof, e.g. vehicles with an aluminium chassis, glass roofs or carbon fibre bodywork.

RLACS171 Dual antenna pole

Dual Antenna Mounting Pole (RLACS171)

This mounting system is used to extend antenna separation for slip angle and other dynamic tests to up to 2.5 m.

RLACS216 IMU Roof Mount

Other Mounts

IMU-integrated Antenna Mounts (several options)

Please see the Inertial Measurement Unit page for all roof mounting options for an IMU/ GPS antenna setup.

Placement

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: On or 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.
