Claim 12:
13. The method according to claim 1, wherein:
evaluating the received GNSS satellite signals to ascertain GNSS sensor data includes using a GNSS sensor to generate data associated with at least one of a current position, a velocity, an attitude, and an acceleration of the GNSS sensor; and
rating the received GNSS satellite signals includes identifying the GNSS satellite signals as performance ensured or not performance ensured based upon one or more of
whether a number of visible satellites is less than a visible satellite threshold,
whether horizontal dilution of precision (HDOP) is greater than an HDOP threshold,
whether correction data are unavailable and/or age of the correction data for a determined minimum number of satellites is greater than an age threshold,
whether a carrier to noise ratio is less than a carrier to noise ratio threshold,
whether an angle of elevation of a determined number of satellites is less than an angle of elevation threshold, and
whether navigation reports of a determined number of satellites indicate the respective satellites are not healthy.
