چکیده
Summary A comprehensive study on the autonomous orbit determination (AOD) performance of satellite pairs in halo orbits and distant retrograde (DROs) is carried out. factor called dynamic geometric dilution precision (DAGDOP) proposed to simultaneously incorporate influences from dynamics geometry pairs. Based DAGDOP, effect different observation arcs AOD accuracy investigated. Next, three types pairs—halo+halo, DRO+DRO, halo+DRO—is systematically analyzed. The hybrid halo+DRO type shows best overall accuracy. Finally, verified a realistic model. Our studies find that average about 170 meters, DRO 190 meters. relative time synchronization error two satellites less than 30 nanoseconds.

15 صفحه اولResults of Long-Duration Simulation of Distant Retrograde Orbits
Distant Retrograde Orbits in the Earth-Moon system are gaining in popularity as stable ‘parking’ orbits for various conceptual missions. To investigate the stability of potential Distant Retrograde Orbits, simulations were executed, with propagation running over a thirty-year period. Initial conditions for the vehicle state were limited such that the position and velocity vectors were in the Ea...
متن کاملImprovements in lunar gravity field modeling and orbit determination from SELENE multi-satellite tracking data types
The launch of SELENE, which acquired the first direct tracking data over the farside of the Moon by the use of 4-way Doppler data between a relay satellite and the main satellite, has resulted in a dramatic improvement of the knowledge of the global lunar gravity field[1,2]. In addition to the 4-way Doppler data, same-beam differential VLBI data between the two sub-satellites and two stations o...
