Latest Patents

One of his latest patents is titled "Method for efficiently detecting impairments in a multi-constellation GNSS receiver." This invention describes apparatuses, methods, and systems designed for a receiver of signals from various satellite navigational systems. The goal is to detect and eliminate impaired satellites and signals, as well as to filter out false positives from the set of satellites being estimated or acquired. The method involves acquiring coarse position, time, and frequency values for multiple satellites and selecting a set based on whether their corresponding acquired coarse values fall within a minimum range. An intersection point of the position domain correlograms generated from vectors of each satellite in the selected set is determined, allowing for the elimination of satellites and signals that do not meet the criteria.

Another patent under his name also focuses on the efficient detection of impairments in a multi-constellation GNSS receiver. This method includes acquiring coarse position, time, and frequency values for satellites currently estimated to be in view. It determines whether these values are within a minimum range and identifies impaired satellites based on their cross-correlation peaks in relation to a pseudo-true peak of a position domain correlogram.
