光学追跡による近静止衛星の軌道決定精度

抄録

Assuming that an optical telescope observes the line-of-sight direction of a near-synchronous satellite, the error in the orbit determination and prediction is theoretically assessed and formulated. The formulations clarify how the orbit determination accuracy increases as the optical tracking period elongates from one night to two nights or more. The theoretical formulations agree with optical tracking experiments.
