The purpose of this paper is to show that absolute orbit determination can be achieved based on spacecraft formation. The relative position vectors expressed in the inertial frame are used as measurements. In this scheme, the optical camera is applied to measure the relative line-of-sight (LOS) angles, i.e., the azimuth and elevation. The LIDAR (Light radio Detecting And Ranging) or radar is used...
In this paper, Mars autonomous navigation using land beacons is investigated. The land beacons placed on Mars surface are used to communicate with the spacecraft orbiting around Mars, and the range measurements between the spacecraft and land beacons are assumed to be available. Since the measurement geometry determines the system observability, the Fisher information index is proposed to autonomously...
In this paper, the Mars final approach navigation is fulfilled using radiometric measurements from ground-based beacons and orbiters. In the navigation system, the beacons are fixed on the surface of the Mars and orbiters can be phased to cooperate with the probe. The trajectory of the Mars probe and the true anomalies of the orbiters are the design variables that should be optimized. The propagation...
Autonomous orbit determination of satellite formation is considered using the measurements between two satellites. This system can accomplish autonomous navigation by using radio cross-link to measure the relative range and optical devices to measure the relative bearing between the two satellites. With the assumption that one satellite knows its attitude information in the inertial reference frame,...
