Kratos Announces Space Domain Awareness Services to Assess Spacecraft Orbiting in Close Proximity to Each Other

Passive RF Ranging Gives the Unique Ability to Identify Spacecraft and Location with Great Accuracy

SAN DIEGO, Sept. 15, 2020 (GLOBE NEWSWIRE) -- Kratos Defense & Security Solutions, Inc. (Nasdaq: KTOS), a leading National Security Solutions provider, announced it will begin offering data services to characterize spacecraft in Geosynchronous Orbit (GEO). This has great value for Space Domain Awareness (SDA) and will be offered to government and commercial organizations internationally.  Services will provide highly accurate proximity operation data, real-time maneuver detection and accurate location data, referred to as ephemeris. Services offering high rate of refresh for closely tracked spacecraft will also be available.

Kratos services will identify and accurately locate spacecraft in GEO using a powerful Space Domain Awareness (SDA) technique called Passive RF Ranging. Traditionally, the ephemeris of a unique spacecraft at GEO is derived from data obtained through ground-based radars and optical telescopes. Oftentimes, these resources cannot correctly differentiate between Closely Spaced Objects (CSOs) accurately enough to provide precise measurements, are unavailable during solar or weather exclusions, or are not geographically accessible. Kratos is not limited by these factors and can provide extremely accurate data related to the location of a spacecraft or multiple spacecraft at a specific moment in time, even when they are critically close (less than one kilometer away).

“The measurements produced by Kratos’ RF Passive Ranging service are valuable because they are highly accurate, allowing operators and users to know exactly where the satellites are and where they will be with respect to each other. Accurate data during proximity operations provides critical insight to operators for vehicle safety,” said Fred W. Gaudlip, Senior Director of Space Domain Awareness Solutions.  “Among the challenges for SDA is the capability to maintain active custody of specific spacecraft.  Active custody includes determining when spacecraft go missing, regions to search for missing spacecraft and correctly identifying the right spacecraft as the previously missed object when finally found.  Tracking spacecraft with high rate refreshes ensures unexpected spacecraft maneuvering will not affect maintaining original custody.”
