New Optical Navigation Results Using Historical MESSENGER Data

Vaishnavi V. Ramanan·Michael A Shoemaker·Andrew J. Liounis

Abstract

This paper describes new optical navigation (OpNav) results obtained by processing previously collected measurements from the MESSENGER mission to Mercury. This project also serves to mature the tools and capabilities of NASA Goddard Space Flight Center (GSFC) in OpNav, using the open source Goddard Image Analysis and Navigation Tool (GIANT). New navigation measurements are obtained during the Mercury flyby and orbital phases, using OpNav measurements generated by GIANT, and these measurements are compared to predictions. The results obtained provide a set of improvements to be made in navigation tools and will pave the way for future missions to navigate near terrestrial bodies using optical measurements.

Demonstration of the Orion Optical Navigation System on Artemis I

The Orion Optical Navigation (OpNav) System is a first-of-its-kind navigation capability that was demonstrated in space on the Artemis I mission. The OpNav System was tested under a variety of conditions, resulting in over one thousand images of Earth, Moon, and starfields. Pairing the images with ground tracking information, not only did Artemis I provide a basis to evaluate the performance of the Orion OpNav system, but produced a valuable set of imagery/data that can be used to further development and testing of other optical navigation systems.

Optical Deep-Space Instrument for Navigation (ODIN)

The Optical Deep-Space Instrument for Navigation (ODIN) is a proposed multiple camera, multiple field of view, optical navigation (OPNAV) instrument currently under development. ODIN aims to create a self-sufficient system which can perform imaging target acquisition, star field based attitude estimation, and position estimation using horizon-based OPNAV of known celestial bodies. ODIN will complete these tasks autonomously, thereby contributing to the advancement of OPNAV as an option for truly autonomous mission operations.
