Abstract:
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, wherein the geolocation server further includes a GPS section, and wherein the at least one server aiding database includes a server environmental database and a server dynamic learned environmental (“DLE”) database, and wherein the position-determination section further includes at least one client aiding database, a client position-determination modules and a client fusion module, and wherein the at least one server aiding database includes a server environmental database and a server dynamic learned environmental (“DLE”) database and wherein the at least one client aiding database includes a client environmental database and a client DLE database, and wherein the position-determination section further includes at least one sensor, and wherein the server position determination module is in signal communication with the GPS section, non-GPS positioning server, at least one server aiding database, and server fusion module, and wherein the server position determination module is configured to receive GPS data from the GPS section, non-GPS positioning data from the non-GPS positioning server, and database data from the at least one server aiding database, and in response produce position-determination data that is passed to the server fusion module, and wherein the server fusion module is in signal communication with the at least one aiding database, and wherein the server fusion module is configured to receive the position-determination data and fuse it together.
