We present a novel method to select waypoints from aerial images of candidate flying regions via matching suitability analysis, which is based on visual attention mechanism and feature attribute classification. At first, visual attention mechanism is

In the integrated inertial navigation system (INS) and celestial navigation system (CNS), the attitudes and positions of probes are estimated based on the auxiliary measurement of an infrared Earth sensor. The poor accuracy of the infrared Earth sens

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 altitudes, and renders the celestial navigation system (CNS) unable to

Traditional star image identification methods use adjacent stellar angular distances to form identification features. The missed detection of high-magnitude stars due to noise interference affects their identification accuracy. We propose a star imag

Navigation systems are crucial space detector components. Advancements in optical equipment have made the Celestial Navigation System (CNS) continually more accessible. Ephemeris error, however, limits the CNS navigation accuracy. This paper proposes

In the integrated navigation of Inertial Navigation Systems (INS) and Celestial Navigation Systems (CNS), small stellar angular distances in a single field-of-view (FOV) star sensor lead to inaccurate navigation parameter estimations. A novel, INS/CN
