Celestial navigation is designed for star identification and confirmation of satellite attitudes in the space. A new celestial navigation technology is based on dual-star-sensor for the sake of high accuracy and reliability. Two star-sensors are set on the satellite, and there is an angle between the light axis of these two star-sensors. So these two star-sensors are designed pointed to the different direction in the space. Modeling and simulation of celestial background which is used in the ground-testing for dual-star-sensor displays two different celestial scenes during navigation process by real-time graphics technology according to the two sensors’ orientation. |
