摘要： In a method for providing location-based information over a network, a plurality of GPS reference data sets, corresponding to a plurality of respective local areas, are acquired at intervals such that each GPS reference data set is updated on a continuous basis. A plurality of aiding data sets are generated at intervals based on the respective GPS data sets, whereby each aiding data set is updated on a continuous basis. The generated aiding data sets are stored at intervals on a data-storing network server, whereby updated aiding data sets are available on a continuous basis for access by a requesting entity via communication with the data-storing network server.

摘要： The invention relates to an aided Global Positioning System (GPS) subsystem within a wireless device. The wireless device includes a wireless processing section capable of receiving signals from a wireless network and a GPS subsystem having a radio frequency (RF) front-end capable of receiving a GPS satellite signal. The wireless processing section of the wireless device receives an external clock and determines the offset between the clock in the wireless processing section and that of the external clock. The GPS subsystem then receives the offset information from the wireless processing section, information related to the nominal frequency of the wireless processing section clock and the wireless processing section clock. Using this information and the GPS clock in the GPS subsystem, the GPS subsystem determines an acquiring signal, which is related to a frequency offset between the GPS clock and the network clock. The GPS subsystem then acquires GPS satellite signals in an acquiring unit though the use of the acquiring signal.

摘要： An Aided Location Communication System ('ALCS') is described that may include a geolocation server and a wireless communication device having a GPS section where the GPS receiver section is capable of being selectively switched between a standalone mode and at least one other mode for determining a geolocation of the wireless communications device. An Aided Location Communication Device ('ALCD') is also described. The ALCD includes a position-determination section having a GPS receiver and a communication section where the position-determination section is selectively switchable between a GPS-standalone mode and at least one other mode for determining a geolocation of the ALCD.

摘要： A receiver reference oscillator frequency correction system and method are described that provides a receiver with a greater ability to lock onto relatively weak radio frequency signals by determining and estimating an amount of frequency error in a local frequency reference of the receiver, and using the error estimate to maintain frequency coherence with a received signal, thereby allowing tracking over a longer period of time, enabling longer integration times to capture weaker signals without losing frequency coherence.

摘要： An Aided Location Communication System ('ALCS') is described. The ALCS may include a geolocation server including a non-GPS position server, at least one server aiding database, server position-determination module, and a server fusion module. The ALCS may also include an Aided Location Communication Device ('ALCD') including a communication section in signal communication with the geolocation server, and a position-determination section having a GPS Engine.
