The main task of GPS receiver in the SDIP system is determination of the vehicle position based on signals received from at least 4 satellites. An additional function fulfilled by GPS receiver is time synchronization on the onboard computer.
Based on indications of this device we can establish a number of parameters in the passenger information system:
- detection of vehicle position in relation to stop,
- crossing the borders of defined zones,
- recognition of detection points for the needs of establishing priorities for vehicle travel through an intersection,
- saving timestamp and geographic position in devices cooperating with GPS receiver (onboard computer, video recorder).
Industrial GPS receiver is designed for mounting in vehicles provided with electrical installation with power supply ranging between 16V and 36V.
