System and method to provide an asil qualifier for gnss position and related values

A method, comprising:

• obtaining data at a sensor;
• executing one or more hardware platform diagnostics on one or more platforms associated with the sensor to determine if the one or more platforms passes or fails the one or more hardware platform diagnostics;
• assigning a hardware platform good qualifier as a hardware platform qualifier when all of the one or more hardware platform diagnostics pass and assigning a hardware platform bad qualifier as the hardware platform qualifier when at least one of the one or more hardware platform diagnostics fails;
• executing a RAIM algorithm on the data to compute at least a protection level;
• assigning an output good qualifier as an output qualifier when the protection level does not exceed an alert limit and assigning an output bad qualifier as the GNSSPS output qualifier when the protection level exceeds the alert limit;
• assigning an Automotive Safety Integrity Level (ASIL) good qualifier as an ASIL qualifier when the output qualifier is assigned the output good qualifier and the hardware platform qualifier is assigned the hardware platform good qualifier;
• and
• assigning an ASIL bad qualifier as the ASIL qualifier when the output qualifier is assigned the output bad qualifier or the hardware platform qualifier is assigned the hardware platform bad qualifier.

A system comprising:

• A Global Navigation Satellite System Position Sensor (GNSSPS) configured to calculate an absolute position based on one or more satellite signals received at an antenna;
• one or more platforms, associated with the GNSSPS, configured to:
• execute one or more hardware platform diagnostics on the one or more platforms to determine if the one or more platforms pass or fail the one or more hardware platform diagnostics,
• a GNSS safety sub-system, of the GNSSPS, configured to:
• assign a hardware platform good qualifier as a hardware platform qualifier when all of the one or more hardware platform diagnostics pass and assign a hardware platform bad qualifier as the hardware platform qualifier when at least one of the one or more hardware platform diagnostics fails,
• execute a RAIM algorithm on the absolute position to compute at least a protection level and remove faulty measurements,
• assign a position good qualifier as a position qualifier when the protection level does not exceed an alert limit and assign a position bad qualifier as the position qualifier when the protection level exceeds the alert limit,
• assign an Automotive Safety Integrity Level (ASIL) good qualifier as an ASIL qualifier when the position qualifier is assigned the position good qualifier and the hardware platform qualifier is assigned the hardware platform good qualifier, and
• assign an ASIL bad qualifier as the ASIL qualifier when the position qualifier is assigned the position bad qualifier or the hardware platform qualifier is assigned the hardware platform bad qualifier.
