1. A method of autonomous orbit projection performed within a Global Navigation Satellite System (GNSS) receiver, said method comprising:
- receiving distinct broadcast orbits from a GNSS satellite, said distinct broadcast orbits received in a GNSS receiver over time during operation of said GNSS receiver;
storing a plurality of said distinct broadcast orbits within said GNSS receiver;
converting a plurality of said stored broadcast orbits into a time series of range data for said GNSS satellite, said converting performed within said GNSS receiver; and
determining a projected orbit for said GNSS satellite by utilizing said time series of range data as an input to an orbit projector of said GNSS receiver.

Abstract
In a method of autonomous orbit projection performed within a Global Navigation Satellite System (GNSS) receiver, distinct broadcast orbits are received over time from a GNSS satellite during operation of the GNSS receiver. A plurality of the distinct broadcast orbits are stored within the GNSS receiver. Within the GNSS receiver, a plurality of the stored broadcast orbits are converted into a time series of range data for the GNSS satellite. A projected orbit for the GNSS satellite is determined by utilizing the time series of range data as an input to an orbit projector of the GNSS receiver.
