EurEx-Safe Long-Term Navigation

The Project "EurEx-Safe Long-Term Navigation" will improve the navigation abilities of autonomous systems in order to make them more reliable during prolonged missions. This is a key ability if complex missions are to be undertaken in scenarios, where external infrastructure and sensors are limited. The scenario in which the navigation ability will be put to the test is the EurEx-scenario, which is a mission scenario to Jupiter’s moon Europa. While such a mission will happen in the far future, EurEx-SiLaNa will work towards making such a mission a reality. One of the steps is to conduct an analogue-mission on earth, in which the feasibility of the mission scenario is demonstrated. The preparation of such a demonstration mission is part of the SiLaNa project, focussing of mission critical aspects: long-term under-ice navigation and robustness of the vehicles Leng and Teredo.

Schematic overview of a possible mission scenario. 0) ice-drill penetrated the ice-shield. 1) AUV has been released from the payload compartment. 2) AUV descends to ocean floor. 3) exploration using cameras/sonar and internal sensors. 4) ascend to the ice/water boundary. 5) return to ice-drill (using autonomous localization buoys) and docking for energy/data exchange.
