摘要
Technology to determine a satellite's orbit is disclosed. In an example, an orbital determination (OD) device for a satellite operable to determine a satellite's orbit can include computer circuitry configured to: Receive a single global positioning system-generated (GPS-generated) signal from a GPS satellite; decode an ephemeris of the GPS satellite from the GPS-generated signal; determine a Doppler shift and a Doppler trend of the GPS-generated signal; and generate a Doppler-GPS OD using the ephemeris of the GPS satellite and the Doppler shift and the Doppler trend of the GPS-generated signal fit to Kepler orbital elements of an orbit model.
