Abstract: An efficient satellite vehicle (SV) tracking mode that, when utilized by user equipment (UE), consumes less power and/or computing resources of the UE than a default SV tracking mode of tracking all visible SV, while maintaining consistent signal quality and/or positional, navigational, and/or timing information accuracy standards. Furthermore, use of the efficient SV tracking mode may be determined and implemented based on a signal environment associated with a location of the UE. In particular, the efficient SV tracking mode may be associated with a location based on a determination that signal quality thresholds are met during use of the efficient SV tracking mode at the location. Additionally or alternatively, the location may be associated with a geofenced area. The geofenced area may define a geographical area corresponding to implementation of the efficient SV tracking mode by a UE located within the geofenced area.
