摘　　要：利用光学导航敏感器进行深空自主导航在国际上已成为一种发展趋势,这种方法具有自主性强、精度高、节约成本等优点,且距离地球越远越显优势.在国内首次开展了用于深空巡航段的自主光学导航敏感器设计研制和验证工作,所研制的光学导航敏感器原型样机设计技术指标为:焦距953.8mm,视场角0.8°×0.8°,探测极限灵敏度12Mv,测量精度0.5″(1σ),动态范围100∶1.试验室测试和外场观星试验的结果表明,测量精度达到0.5″(1σ),探测极限灵敏度达到12.5Mv,技术指标全部满足要求.Application of an optical navigation sensor（ONS） is a tendency for deep space navigation in the world.The method has many benefits such as good autonomous ability,high accuracy,low cost and so on.Design,development,and validation of the ONS are first discussed in China in this paper.The main technical parameters of the ONS are as follows： the focal length is 953.8mm,the field of view is 0.8°×0.8°,the limiting detection sensitivity is 12 Mv,the measurement accuracy is 0.5″,and the dynamic range of response is 100∶ 1.The test results in the laboratory and stars observation station indicate all the technical parameters of the ONS＇s prototype example are realized.
