报告主题:Relative Navigation for In-orbit Servicing of Non-cooperative Spacecraft


Robotic servicing is a key technology for enabling autonomous on-orbit servicing and the manipulation (e.g. repair) of spacecraft. Moreover, it can be used as an assistance system on manned space missions releasing astronauts from performing difficult and dangerous operations. An indispensable subtask of on-orbit servicing is the rendezvous (RV) navigation between an approaching spacecraft (called chaser) and a target object (e. g. spacecraft or space debris). Due to the risk of collision the requirements for accuracy and robustness are very high. For rendezvous with damaged satellites or space debris further challenging conditions must be considered: the target is supposed to be passive (maybe tumbling), it must be assumed in general being non-cooperative or unprepared and its 3D structure is maybe even unknown. Vision based perception systems with cameras (visual, infrared) and laser distance sensors (LIDAR) offer promising capabilities for recovering both the target’s relative pose (position and orientation) and its geometrical structure from image data. Due to unfavorable environmental conditions (illumination, reflections, and thermal variations) the processing of the image data and the estimation of pose and 3D structure put several algorithmic challenges for realistic missions.

The lecture introduces the key drivers for algorithms development and reports on recent and current research results on the pose and geometric structure estimation of our TU Dresden Automation Engineering Lab, e.g. an ongoing project with European Space Agency for servicing the ENVISAT satellite (see Figure 1).
