Finally, based on the observability analysis and error analysis, two autonomous navigation schemes for encounter phase are respectively proposed in detail. monte carlo simulations are done for the two schemes. by analyzing and comparing the simulation results, we can get the conclusion that, under the accuracy conditions provided by the instruments in existence, the position estimation accuracy for probe encountering object celestial body is 0. 42km and 0. 04km, which demonstrate the feasibility of the two navigation schemes
最後,在可觀性分析和誤差分析的基礎上,分別給出基於圖像測量的自主導航方法和基於視線方向及夾角測量的自主導航方法,並對這兩種方法進行蒙特卡羅數值模擬,通過對模擬結果的分析和比較,在現有儀器的測量精度下,探測器在與目標天體交會時刻的位置估計精度分別是0 . 42km和0 . 04km ,由此表明兩種自主導航方案都是可行的。
