Abstract :
Discusses interplanetary missions using continuously low-thrust systems. This paper describes an Earth-based orbit estimation capability for electric propulsion spacecraft in the light of recent developments both in few station tracking concepts and in thrust subsystem error modeling. Both suboptimal and optimal orbit determination performance are determined for a wide range of process noise parameter values.
