Autonomous Orbit Determination For Two Spacecraft From Relative Position Measurements
JOURNAL OF GUIDANCE CONTROL AND DYNAMICS(1999)
摘要
A batch filter has been designed and analyzed to autonomously determine the orbits of two spacecraft based on measurements of the relative position vector from one spacecraft to the other. This system provides a means for high-precision autonomous orbit determination for systems that cannot he dependent on signals from the global positioning system constellation or ground stations. The hi ter uses a time series of the inertially referenced relative position vector, and it uses orbital dynamics models for the two spacecraft. It estimates the 6-element orbital state vectors of both spacecraft along with a drag parameter for each one. The observability of this system is demonstrated in this proof-of-concept study, and the filter's best-case achievable position accuracy is estimated for a number of situations. Position accuracies on the order of I-m rms may be possible for certain configurations.
