Bias Estimations for Ill-posed Problem of Celestial Positioning Using the Sun and Precision Analysis

Lunar/Mars rovers own sun sensors for navigation, however, long-time tracking for the sun impacts on the real-time activity of navigation. Absolute positioning method by observing the sun with a super short tracking period such as 1 or 2 minutes is researched in this paper. Linear least squares mode...
