Systems and methods for location positioning of user device

摘要

Devices, systems, and methods for gathering, calculating and sending positioning information at a user device to one or more networks may be disclosed. In a first implementation the user device transforms pseudorange information relating to terrestrial beacons into GNSS pseudorange information. In a second implementation, the user device sends position information using GNSS information elements. In a third implementation, the user device sends position information using non-GNSS information elements.

主权项

1. A method for determining position data used to estimate a position of a receiver, the method comprising:
determining a first set of estimated distances between a receiver and each of a plurality terrestrial transmitters based on positioning signals transmitted by the terrestrial transmitters; determining an estimated location of the receiver using the first set of estimated distances; determining a second set of estimated distances between each of a plurality of satellites and the estimated location of the receiver using the estimated location of the receiver and constellation information associated with the plurality of satellites, wherein the constellation information associated with the plurality of satellites includes a position and a timing correction for each of the plurality of satellites at a reference time; and transmitting the reference time and the second set of estimated distances to a computing device.
