1. An Aided Location Communication System (“
- ALCS”
), comprising;
an geolocation server including a non-GPS position server, at least one server aiding database, server position-determination module, and a server fusion module; and
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, wherein the ALCD is capable of selectively switching between a first position-determination mode for determining a geolocation of the ALCD and a second position-determination mode for determining the geolocation of the ALCD.

Abstract
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.

13. A method for determining the geolocation of an Aided Location Communication Device (“
- ALCD”
), having a position-determination section and a communication section, within an Aided Location Communication System (“
ALCS”
), the method comprising;measuring characteristic information for a communication network of the ALCS; comparing the measured characteristic information against position data stored in an aiding database; determining an initial coarse position for the ALCD based on the comparison of the measured characteristic information against position data stored in an aiding database; determining whether the initial coarse position is acceptable; determining the position of the ALCD if the initial coarse position is not acceptable; fusing the measured characteristic information with the initial coarse position if the initial position is acceptable or fusing the measured characteristic information with the determined position if the initial position is not acceptable; and updating the aiding database with the fused data. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
