Satellite orbital determination (OD) using Doppler and Kepler orbital elements |
| 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. |

1. An orbital determination (OD) device for a satellite operable to determine a satellite's orbit, the OD device having 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 trend of Doppler shift of the GPS-generated signal; and generate a Doppler-GPS OD using the ephemeris of the GPS satellite and the Doppler shift and the trend of Doppler shift of the GPS-generated signal fit to Kepler orbital elements of an orbit model. |
