Abstract
Official abstract text for this publication.
Systems, methods and devices for improving the accuracy of GNSS data are provided. Specifically, embodiments of the invention can advantageously use sensor input to improve the accuracy of position fixes. The use of physical 5 sensors in navigation systems is deemed particularly advantageous, especially where altitude data derived from the pressure sensor is calibrated with and/or blended with GNSS altitude data.
First claim
Opening claim text (preview).
The invention claimed is: 1. A navigation receiver, comprising: a pressure sensor configured to provide a pressure sensor signal; a satellite receiver configured to provide pseudoranges associated with one or more satellites; and one or more position filters configured to: generate a position based, at least, on a pseudorange offset for a particular satellite of the one or more satellites, wherein the pseudorange offset, indicative of a multipath error of the particular satel…
