Future space exploration missions require increased autonomy. This is especially true for
navigation, where continued reliance on Earth-based resources is often a limiting factor in …

Time delay is a novel celestial navigation measurement that can provide the distance
information of the spacecraft relative to the nearby celestial body. Combining time delay …

Solar oscillations cause significant variations in sunlight spectral wavelength and intensity
over short time periods. These oscillations have been studied in detail over the years, both …

This paper proposes a novel Takagi-Sugeno fuzzy predictor observer to tackle the problem
of the constant and known delay in the measurements. The proposed observer is developed …

Abstract Space navigation has been a research topic for decades, with autonomy within its
remit being a challenging area. Conventional space navigation approaches are based on …

Recent advancements in CubeSat technology unfold new mission ideas and the opportunity
to lower the cost of space exploration. Ground operations costs for interplanetary CubeSats …

To improve the positioning accuracy of autonomous celestial navigation systems when flying
in formation, we exploit the fact that the sole light source in the solar system is the Sun to …

The time dispersion effect affects the accuracy of solar time difference of arrival (TDOA)
navigation. In this celestial autonomous navigation, Mars's moons are reflecting celestial …

The navigation stars captured by the star sensor are far away from the spacecraft; this
creates a strong similarity among star images at similar locations, attitudes but different …

太阳震荡可以在短时间内引起太阳光强度和光谱线心波长的剧烈变化, 通过探测太阳光强度和
光谱线心波长并记录时间, 可以获得直接接收的太阳光到达时间和经天体反射的太阳光到达时间 …
