METHOD FOR EFFICIENTLY DETECTING IMPAIRMENTS IN A MULTI-CONSTELLATION GNSS RECEIVER
Apparatuses, methods, and systems are described for a receiver of signals from one or more satellite navigational systems to detect and/or eliminate impaired satellites/signals and/or "false positives" from the set of satellites being estimated/acquired. One method includes acquiring coars...

| description | Apparatuses, methods, and systems are described for a receiver of signals from one or more satellite navigational systems to detect and/or eliminate impaired satellites/signals and/or "false positives" from the set of satellites being estimated/acquired. One method includes acquiring coarse position, time, and frequency values for each of a plurality of satellites from one or more satellite navigational systems and then selecting a set of satellites based on whether one or more of their corresponding acquired coarse values are within a minimum range. An intersection point of the position domain correlograms generated from vectors of each satellite in the selected set is determined and, using that intersection point, satellites/signals are eliminated from the selected set of satellites. |
