Abstract
A system and method provides an Automotive Safety Integrity Level (ASIL) qualifier for Global Navigation Satellite System (GNSS) position and related values. Specifically, hardware platform diagnostics are executed on one or more platforms associated with a GNSS Position Sensor (GNSSPS) that calculates/obtains position and/or related values. Also, a Receiver Autonomous Integrity Monitoring (RAIM) algorithm is executed on the calculated/obtained position and/or related values. If the results both produce a 'good' qualifier, the position and/or related values is assigned an ASIL qualifier of 'good' and may be utilized by an ASIL rated system. If either of the qualifiers is a “bad” qualifier, the position and/or related values is assigned an ASIL qualifier of “bad” and cannot be utilized by the ASIL rated system. In addition, the inventive system and method may compute a probability associated with an integrity violation of the RAIM algorithm which may consider the probability of hardware failure.
