SYSTEMS, METHODS, AND MEDIA FOR CALCULATING AN OVERBOUND DISTRIBUTION, FROM A BASE MIXTURE DISTRIBUTION, THAT CAN BE USED WITH A SOLUTION-SEPARATION RAIM ALGORITHM
An overbound distribution is calculated from a base mixture distribution. For a bounded region, the base distribution is lower-bound at an evaluation point with a second-order polynomial of the base distribution and upper-bound at the evaluation point with a first-order polynomial of a single distribution with a standard deviation value calculated from the base distribution. If the step size from the evaluation point to an intersection of the lower and upper bounds is less than a threshold, the standard deviation value can be iteratively increased until the step size exceeds the threshold. The process is performed for additional portions of the base distribution up to a critical value to determine a final adjusted standard deviation value for the single distribution that is tightly bound to the base distribution and that can be used by a solution algorithm to determine a solution (used to seed filter states for a navigation filter).

System and method to provide an ASIL qualifier for GNSS position and related values
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.

A system for determining precise position includes a chirp receiver that processes broadcast chirp signals in the frequency domain to distinguish direct path signals from multipath signals. The chirp receiver processes the received chirp signals, which consist of respective pulsed frequency sweeps, by combining a received chirp signal with a synchronized locally generated chirp signal and phase adjusting and concatenating the results over multiple sweeps, based on estimated clock phase errors and expected phase rotations of the direct path signals, to produce a sine wave. The phase adjustment and concatenation allows the use of longer Fast Fourier Transforms (FFTs) that, in turn, provide increased accuracy of frequency estimation and separate component signals that are very close in frequency. The phase adjustment and concatenated signals are processed in the frequency domain using an FFT and a frequency corresponding to the direct path signal is identified by the lowest frequency bin in which power is above a predetermined noise threshold. The receiver then determines a time delay based on the identified frequency and uses the time delay to calculate accurate clock phase error. The system may then determine position based on associated pseudorange measurements.
