VEHICLE AUTOMATIC EMERGENCY RESPONSE SYSTEM
An automatic emergency response system (12) is operable to notify an emergency centre (27) of a defined event, such as a vehicle accident. The system facilitates location of the event, by using position determining means, such as GSP (18), to establish its at least approximate location. A control circuit (19) includes code generating means to generate a coded signal incorporating the position location information. An alarm signal transmitter (16) is operable on occurrence of the defined event to transmit an alarm signal incorporating the coded signal to a receiving station (26), which may be a satellite, which relays the message to the emergency centre (27), including the positional information relating to the location of the transmitter (16). A relative low power homing signal transmitter (17) simultaneously transmits a homing signal either continuously or at periodic intervals.
