Viking Satellite Orbit Determination
Journal of Guidance and Control, 1977During the summer of 1976, the two Viking spacecraft, each consisting of an orbiter-lander combination, were inserted into orbit about Mars. The paper describes the experiences of the Viking Satellite Orbit Determination Team in determining Mars centered ephemerides of the orbiters and positions of the landers from the two-way Doppler and range data ...

AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 2008
In 2006, an updated version of SGP4 was presented for general use. The propagation routine relies on Two-Line Element (TLE) set data provided by the U.S. Government for several decades. Many independent organizations have access to observations, or ephemerides developed with other programs. Because the TLE is a compact means to obtain modestly accurate

Inter-Satellite Link Enhanced Orbit Determination for BeiDou-3
Journal of navigation, 2019The third generation of the BeiDou navigation satellite system (BDS-3) is a global navigation system, and is expected to be in full operation by 2020. High-precision orbits are a precondition for BDS-3 to provide a highly accurate service, which needs a ...

Orbit Determination: Preliminary Orbits
1985Having at our disposal at the Observatory some photographic plates of artificial satellites and, also, facilities to get plates of natural celestial bodies of the solar system, by the installation of a new optical telescope, we had need to write a computer program for a fast determination of preliminary orbits, both geocentric and heliocentric, by ...

Determining orbits for natural and artificial celestial bodies is an essential step in the exploration and understanding of the Solar System. However, recent progress in the quality and quantity of data from astronomical observations and spacecraft tracking has generated orbit determination problems which cannot be handled by classical algorithms. This

Orbit determination of the Lunar Reconnaissance Orbiter
Journal of Geodesy, 2011We present the results on precision orbit determination from the radio science investigation of the Lunar Reconnaissance Orbiter (LRO) spacecraft. We describe the data, modeling and methods used to achieve position knowledge several times better than the required 50–100 m (in total position), over the period from 13 July 2009 to 31 January 2011.

Simultaneous orbit determination
26th Aerospace Sciences Meeting, 1988Simultaneous orbit determination is demonstrated using live range and Doppler data for the NASA/Goddard tracking configuration defined by the White Sands Ground Terminal (WSGT), the Tracking and Data Relay Satellite (TDRS), and the Earth Radiation Budget Satellite (ERBS).
