Abstract
Systems and methods according to various embodiments provide for navigation in attenuated environments by integrating satellite signals with Internet hotspot signals. In one embodiment, a receiver unit adapted to perform geolocation comprises an antenna adapted to receive a precision time signal from a satellite and receive additional aiding information from a wireless network station, wherein the precision time signal comprises a periodic repeating code. The receiver unit also comprises a processor and a memory adapted to store a plurality of computer readable instructions which when executed by the processor are adapted to cause the receiver unit to: use the precision time signal and the aiding information to determine a precise absolute time, determine positioning information associated with the receiver unit, use the positioning information to request location information of the wireless network station, and determine an absolute geolocation of the receiver unit using the positioning information and the location information.
