Starlight positioning navigation method based on artificial satellite

Abstract

The invention relates to a starlight positioning navigation method based on artificial satellites. Thestarlight positioning navigation method comprises the following steps: firstly, observing three satellites in a space by adopting a star sensor, obtaining position coordinates of the three observed satellites according to satellite ephemeris, and calculating a relative distance between any two satellites; measuring unit direction vectors of three satellites relative to the star sensor by adopting the star sensor, and calculating field angles of any two satellites relative to the star sensor; calculating the relative distance between the star sensor and each satellite; and calculating the position of the star sensor according to the position coordinates of the three satellites and the relative distance between the star sensor and each satellite, thereby realizing the autonomous positioning of the aircraft. According to the invention, the functions of the star sensor are expanded, on the basis of traditional autonomous attitude determination, autonomous positioning is realized, no extra equipment is added, no extra space is occupied, and the method has very high economical efficiency.

AI Technical Summary

Benefits of technology

This technology improves how long it takes for piloted airplanes (a type of navigational aid) to travel accurately without requiring any modifications or specialized devices like GPS receivers that may be expensive at some altitudes. It also allows for precise location tracking during takeoffs and landings while still being able to navigate through different terrains effectively. Overall this innovation makes flying more efficient and cost-effective than current systems.

Problems solved by technology

This patented describes an improved way for navigating by combining both traditional ways - one involves measuring movement from space while another relies solely upon visual observation or other techniques like radar tracking. However, current systems have limited accuracy due to their large sizes and low durability over time. Starlight guided technology solves this problem but still faces challenges such as lack of accurate orientation data during long periods without interference caused by external factors like weather conditions or atmospheric turbulence.
