A method, apparatus, and system are disclosed for providing modified orbital assistance data to a mobile station to determine its location using global navigation satellite system (GNSS). In some example embodiments, a method for determining a location of a mobile station using orbital assistance data may include: receiving satellite positioning signals from a plurality of GNSS satellites; receiving orbital assistance data comprising a distance between a location on an antenna which is associated with a first frequency of the satellite positioning signals and a location on the antenna which is associated with a second frequency of the satellite positioning signals; and determining the location of the mobile station based on the orbital assistance data and the satellite positioning signals.

Antenna phase center compensation for orbital assistance data

In some implementations, a method of facilitating pointing of a mobile device at a satellite of a satellite constellation for satellite-based data communication, may comprise obtaining, at a first time point, historical orbital data indicative of orbital movement of a plurality of satellites of a satellite constellation over a period of time. The method may also comprise assigning a reference orbital dataset of the plurality orbital datasets determined at a reference time point to corresponding control boxes of a reference grid covering the satellite constellation, wherein each control box of the reference grid corresponds to a satellite of the satellite constellation. The method may also comprise mapping the plurality orbital datasets to the reference grid for an orbital model based on the assignment of the reference orbital dataset.

Satellite positioning for satellite-based communications

An example method of geofencing for satellite communication performed by a UE, the method comprising obtaining a first region file comprising a plurality of regions, wherein each region of the plurality of regions is represented by one or more geo-polygons, wherein each region of the plurality of regions corresponds to a respective unique region identifier, and obtaining a first restriction status file comprising restriction status information regarding each region of the plurality of regions. The method further comprises receiving, from a server, a second restriction status file comprising a second set of region identifiers and corresponding restriction status information, determining a difference between the first set of region identifiers and the second set of region identifiers, and updating the first region file, the first restriction status file, or both based on the difference.
