Abstract

Novel Static Infrared Earth Sensor (SIES) was developed for high precision and strong adaptive autonomous optical navigation of Earth orbit satellites. The SIES was designed to obtain infrared image of the entire Earth through the focal plane detectors, which is conducive to obtaining more abundant boundary information, achieving higher measurement accuracy and rejecting irregular interference. By measuring the difference of infrared radiation between the earth and the space with SIES, the horizon circle formed by the earth’s atmosphere radiation circle was obtained, and the orientation of the earth in the inertial coordinate system was determined under integrated autonomous navigation framework. With high-precision Earth center vector measurement and autonomous on-orbit calibration abilities of SIES, the proposed autonomous navigation technology had been successfully verified on geosynchronous orbit, the position determination error was less than 9 km. The SIES is suitable for wide range types of satellites working on 17000 km to 70000 km orbit altitude by providing outstanding accuracy, large field of view, long-term high reliability, light weight and power efficiency.
