The video explains how testing real world situations for development of vehicle satellite navigation systems can be a lengthy and difficult process.
Most modern in-car systems not only use GPS but also dead-reckoning signals from the vehicle itself, so bench testing such equipment can be problematical.
As a result, Racelogic have developed a full navigation system testing system which includes dead-reckoning signals recorded from the vehicle, with a turntable to simulate the vehicle movements.
The video shows the system in action, with a satnav unit being manoeuvred on the turntable whilst it receives a combination of previously record GPS and vehicle signals.
