Abstract: Perception data based multipath identification and correction is based on recognition that sensors such as radar, LIDAR, and cameras can generate perception data indicative of locations and properties of terrestrial objects in an environment surrounding a satellite navigation device (e.g., a GNSS receiver), which data may then be used in training, or updating, a model for determining or correcting distances to satellites to account for multipath. Multipath identification includes identifying multipaths to train the model, e.g., by using perception data to perform ray tracing. Multipath correction includes using the model to correct distance errors due to the multipaths or, equivalently, using the model to determine distances to satellites in a manner that accounts for the multipaths.

Abstract: Accurate long term satellite models for satellites include satellites of different navigation systems. Such a model is derived for a non-GPS satellite that broadcasts native orbital model data specified as valid within a first time period. Initial position and velocity data are determined from the native orbital model data, and orbit integration is performed to determine an orbital arc in an earth-centered-earth-fixed frame over a second time period longer than the first time period. Initial estimates of GPS or GPS-like orbit parameters are determined for the non-GPS satellite, and the orbital arc and the initial estimates of the GPS or GPS-like orbit parameters are input to an orbit parameter solver that determines GPS or GPS-like parameters that fit the orbital arc and is used to determine final orbital model parameters in GPS or GPS-like format for the non-GPS satellite.
