The overarching goal of the VaMEx project is to explore and search for forms of non-terrestrial life in the Valles Marineris, using an autonomous swarm consisting of rovers, crawlers and unmanned aerial vehicles (UAVs). The sub-project VaMEx3-VRN has two main goals: First, to investigate methods for the development of virtual twins that enable early validation and verification of both software and hardware components of an autonomous swarm. The second goal is the development of “terrain relative navigation (TRN)” based on LiDAR, inertial measurement data, and further sensor technology. The ultimate goal is a space-ready software/hardware component, complete with a qualified space-ready computer, error safety, and a verification of the navigation performance using the virtual twin.
