Here's a subset of the companies we have worked with. Sorry, we can't list them all due to NDAs!
Space Exploration Engineering, LLC
Providing detailed orbit determination analysis for a variety of unique pre-mission and operational scenarios covering the near Earth, cis-lunar, lunar, and deep space orbit regimes.
Spaceflux offers Space Situational Awareness services based on optical sensors that track satellites and space debris from LEO to GEO and Cislunar, with 10 locations worldwide and more to come. Thanks to their large sensors of up to 70 cm in diameter, they can track smaller objects compared to the competition. Their sensors can also be tasked and obtain multi-color photometric measurements for enhanced characterisation and custody.
Helped ThothX validate and calibrate the world's first commercial GEO deep space radar (Earthfence). We continue to support ThothX for operational missions that are using their Earthfence radar, including participating in various SACT exercises with the USSF.
