Antennas & Mounts
rovide several 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.
To protect against multipath reflection and when no suitable ground plane is present, mushroom antennas with ground plane are a good option.
A Dual Antenna Mounting Pole (max. width 2.5 m) ensures the most accurate slip angle measurement.
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
Typical antenna placement
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 top of 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.
Antenna Options
1、Low Profile, Magnetic Antennas with no ground plane
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.
2、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.
Antenna Mounting Options
Racelogic offer multiple antenna mounting options for all types of vehicle roof materials and antenna separation and IMU mount requirements.
