Claim 14:
15. A computer program embodied on a computer readable storage medium for processing program code to be executed by a telematics control entity, wherein execution of the program code causes the telematics control entity to carry out a method comprising the steps of:
receiving, by an antenna signal interface of the telematics control entity, satellite-based measurement data;
determining, by at least one position determining unit of the telematics control entity, positioning data of the vehicle based on the satellite-based measurement data;
guaranteeing, by the first measurement entity, a predefined integrity level describing a predefined risk classification of a functional safety provided by the positioning data as determined by the at least one position determining unit;
determining, by the first measurement entity, raw satellite position data from the received satellite-based measurement data;
transmitting the determined raw satellite position data from the first measurement entity to a first positioning entity configured to determine a first position of the vehicle meeting the predefined integrity level based on the determined raw satellite position data;
determining, by the first positioning entity, a first position of the vehicle based on the raw satellite data received from the first measurement entity, the first position meeting the predefined integrity level;
detecting, by a bidirectional communication channel between the first measurement entity and the first positioning entity, invalid, missing or delayed information transmitted between each end of the bidirectional communication channel, the bidirectional communication channel is configured with an end-to-end protection between two ends of the bidirectional communication channel with no modification of information transmitted in the bidirectional communication channel between the two ends of the bidirectional communication channel, each end of the bidirectional communication channel is configured to detect invalid, missing or delayed information transmitted between the two ends of the bidirectional communication channel, the first positioning entity is configured to provide the determined first position as positioning data to the application entity in a further bidirectional communication channel between the first positioning entity and the application entity, the further bidirectional communication channel is configured with an end-to-end protection between two ends of the further bidirectional communication channel with no processing or modification of information transmitted in the further bidirectional communication channel between the two ends, and each end of the further bidirectional communication channel is configured to detect invalid, missing or delayed information transmitted between the two ends of the further bidirectional communication channel; and
providing, by the at least one position determining unit, the determined positioning data to an application entity in the vehicle requiring the predefined integrity level for the received positioning data.
