  • DISTRIBUTED ORBIT MODELING AND PROPAGATION METHOD FOR A PREDICTED AND REAL-TIME ASSISTED GPS SYSTEM
    Publication number: 20150285918
    Abstract: A mobile device includes a processor for generating a predicted orbital state vector using an initial satellite position and velocity and force model parameters received from a server, the predicted orbital state vector being used to generate satellite navigation data; and a GNSS receiver in communication with the processor for receiving the satellite navigation data; wherein the satellite navigation data is valid for a time period.
    Type: Application

  • Distributed orbit modeling and propagation method for a predicted and real-time assisted GPS system
    Patent number: 8004462
    Abstract: A distributed orbit and propagation method for use in a predicted GPS or GNSS system, which includes a predicted GPS server (PGPS Server), a source of high accuracy orbit predictions (Orbit Server), a global reference network (GRN Server) providing real-time GPS or GNSS assistance data to the PGPS Server, a predicted GPS client (PGPS Client) running on a device equipped with a GPS or AGPS chipset. In response to requests from the PGPS Client, the PGPS Server produces and disseminates an initial seed dataset consisting of current satellite orbit state vectors and orbit propagation model coefficients. This seed dataset enables the PGPS Client to locally predict and propagate satellite orbits to a desired future time. This predictive assistance in turn helps accelerate Time To First Fix (TTFF), optimize position solution calculations and improve the sensitivity of the GPS chip present on, or coupled with, the device.
