Abstract: This paper studies the error analysis problem of estimating the parameters of the boost phase of a trajectory under the condition of priori information. A single satellite is applied and the trajectory is measured by the reaching angle of the satellite carried infrared sensor. Through theoretical analysis and combined with Monte Carlo simulation, systematically analyze the influence of three main error source on the trajectory estimation. Some corresponding transaction strategies are also presented.
