Latest Patents

Makarand's latest patents include a method for multiple satellite measurement failure detection and isolation for GNSS. This invention describes methods for reducing the resources needed to detect and identify faulty pseudorange measurements in a GNSS receiver. In this Receiver Autonomous Integrity Monitoring (RAIM) method, a position solution is calculated using a weighted least squares method on measurements from satellites of one or more GNSS constellations. A test statistic is calculated from residuals, and a threshold is determined based on a probability function. If the test statistic meets or exceeds the threshold, a subset of pseudorange measurements is selected using a metric indicative of possible measurement error. A measurement is then chosen from this subset based on signal strength or another relevant metric and discarded from the set of pseudorange measurements. If more than five measurements remain, the method loops back to the position solution calculation step.

Another significant patent is for a system, method, and apparatus for a satellite navigational system receiver to select a subset of tracking satellites. This invention outlines systems, methods, and apparatuses that allow a satellite navigational system receiver to select a subset of tracking satellites from those in view. In this method, after selecting the satellite with the highest elevation, additional satellites are chosen for the tracking subset by sequentially searching the sectors of an azimuth plane map.
