Terrestrial Demonstration of Orbital Mapping and Validation Capabilities over a Lunar Surface Analog

The Lunar Navigation Maps (LuNaMaps) project has improved existing tools and processes and developed new tools and processes to support the generation and validation of navigation maps of the lunar surface from orbital imagery. To demonstrate the advancements made through the LuNaMaps project, we con-ducted a terrestrial demonstration obtaining “orbital” imagery of the Lunar Sur-face Proving Ground (LSPG) at Astrobotic’s test facility in Mojave California. The LSPG is a 100 m by 100 m pad built to mimic the features and appearance of the lunar surface. In this paper we describe the planning and results of the test, including the capture of imagery for building the maps, the map building processes, building of a “truth map” using traditional surveying tools, and the map validation processes. We demonstrate how the built map compares to the “truth map” and how the validation processes provided insight to this compari-son. Additionally, we describe an upcoming partner test in which the naviga-tion maps will be used in a terrain relative navigation (TRN) technology demonstration over the same LSPG surface.
