The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) mission is an ongoing mission to serve as a pathfinder for cislunar operations and navigation for the Lunar Gateway and the greater Artemis program. As part of nominal operations, one of the tracking dishes that CAPSTONE utilizes is DSS-17 at Morehead State University. Through a series of necessary corrections, CAPSTONE has been able to generate radiometric measurements using this dish on the same order of noise magnitude as typical DSN measurements. This paper will provide an overview of the necessary processes and early performance of DSS-17 in CAPSTONE orbit determination.

This study evaluates the potential observability benefits of space-based passive RF systems compared to other ground-based and space-based observers for cislunar Space Domain Awareness. TDoA and FDoA observations are used for orbit determination of objects in the lunar vicinity using observers in GEO and XGEO. The results are compared to ground-based observations in order to analyze the performance gains over existing architectures. Results show using space-based systems result in faster filter convergence and more accurate state estimates.

A few of our team members are attending the 2022 AAS/AIAA Astrodynamics Specialist Conference next week in Charlotte, North Carolina. We invite you to listen to their work being presented, some of which demonstrates great collaboration and support from the NASA Gateway Program. Reach out and learn ways we may support your needs. We look forward to connecting with you. (more…)

Building on previous work in cislunar orbit determination at Advanced Space, this paper demonstrates cislunar orbit determination via simulated optical measurements from another spacecraft in cislunar space. The goal of this work is to evaluate the potential performance (in terms of the uncertainties in the state of a target object) of space-based optical tracking filters in the vicinity of the Moon.
