12 Operation
12.1 Principle of Operation
The CAS GPS product is designed to offer a situational awareness driver aid utilising GPS proximity detection
of vehicles/objects and data logging.
Each vehicle broadcasts its current position and relevant parameters which are used to detect warnings of
possible intersections with other vehicles that receive the broadcast. The position of other vehicles, together with
any warnings is shown graphically on the Display Unit.
The system aids the driver with a continuous view of other objects that are moving, stationary, over the
horizon, just behind the vehicle or simply out of sight due to bad visibility when operating their vehicle. The
system is designed to avoid distracting the driver from driving, but provides the driver with an awareness tool to
notify and visualise other objects surrounding the vehicle on take-off and during operation.
The CAS-GPS system notifies the driver with progressive audible and graphic alerts as shown in the table below.
The system continually broadcasts its location and receives broadcasts of other vehicles in radio
communications for up to 500 meters using the in-built proprietary radio link. Vehicle interactions are projected
based on the trajectories of the vehicles; an alert is triggered and depending on the configuration, an
acknowledgement by the driver on the touch screen may be required (only w
hen the vehicle is stationary).
