Landing an autonomous spacecraft within 100 m of a mapped target is a navigation challenge in planetary exploration. Vision-based approaches attempt to pair 2D features detected in camera images with 3D mapped landmarks to reach the required precision. This paper presents a vision-aided inertial navigation system for pinpoint planetary landing called LION (Landing Inertial and Optical Navigation)...
Virtual simulation is currently a key activity that supports the specification, design, verification and operations of space systems. Taking advantage of dynamics research activities, ESA has currently been developing a multibody software (DCAP) together with industry for more than 30 years heritage in space applications. This software is a suite of fast, effective computer programs that provides...
Through the HybrId NAVigation system (HiNAV) project, Astrium Satellites studies the hybridisation of GNSS and Inertial Measurement Unit (IMU) measurements in a tight aiding / tight hybridisation architecture dedicated to the navigation function of launchers and re-entry spacecrafts. It is also a valuable solution for the safeguard function of launchers. In the frame of this project, the HiNAV product...
