ABSTRACT
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.

The team members at Advanced Space are the key to our success. Meet Dr. Nathan (Parrish) Ré, one of the company’s first employees who has been with the company for almost eight years.
What got you interested in AI for space?
In 2013, about a year into my PhD at CU Boulder, I had a conversation with a childhood friend who was playing with AI computer vision in his free time. I got really interested in it, so I bought a textbook and spent the next year trying to figure out how to apply AI to astrodynamics. At the time, the technology was much less user-friendly and there wasn’t much to go on. It took a few years to figure out a practical application that could also get me my degree. (more…)

The CAPSTONE Countdown is nearly over! We are mere hours from arriving at the Moon, and there would be no mission without the incredible work of the Advanced Space CAPSTONE Mission Operations Team. From orbit determination and navigation to all the details behind the scenes, thank you to this talented team of engineers, technicians, and more: (more…)

ABSTRACT
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.
