Abstract: Satellite positioning system enabled mobile receivers (310) and cellular communication network base stations (330) synchronized with satellite positioning system clocks and method therefore. In a network-assisted embodiment, a variable propagation delay for transmission of an assistance message (232) from the base station to the mobile receiver is determined for correcting the handset clock (318). In others embodiments, local clock drift of mobile receivers (310) and/or base stations (330) are determined by a ratio of local and satellite time differences, based on sequential time snapshots, for use in correcting the local clocks.
