Maximize Satellite Ground Resources

Whatever the mission, all space operations depend upon timely, accurate and detailed information to develop a complete operational picture.

RF Data for Space Situational Awareness

Case Study 1 - How Kratos Helps JFSCC Maximize Satellite Ground Resources
Kratos provides critical enhanced Space Situational Awareness (SSA) as a managed service to the Joint Force Space Component Command (JFSCC). More than just the tracking of physical objects in space, Kratos services track and assure the satellite signals essential to space operations are performing as expected.  Within Kratos’ advanced 24/7 Network Operations Center (NOC), experts monitor, detect and geolocate potential interferers and jamming attempts as well as analyze related data to optimize the availability, reliability and security of communications signals.

Case Study 2 - How Kratos Helps the U.S. Government Proactively Manage Quality of Service
Recently, while the Kratos Network Operations Center (NOC) was monitoring bandwidth for one of their customers, they detected an interfering signal operating in two planned frequency slots.  The interference experienced by the customer was caused by an L-band radar type signal being rebroadcast to the satellite. This customer operates an L-band radar system that is commonly deployed to their facilities, which also feature SATCOM terminals. The radar system can operate in the same L-band frequency range as the SATCOM terminal’s block upconverter (BUC) input. As in this case, if the cable between the user’s modulator and BUC input is damaged or improperly terminated, the high-power radar signal will enter the BUC’s input. At this point, the RADAR is up-converted, amplified, and transmitted to the satellite just like any L-band signal from the user’s modulator.  

Kratos advised the customer of the issue and recommended they move the affected users while resolution efforts took place. Given the severity of this interference, it was likely that at least one of the two affected users would have been significantly impacted through either reduced link throughput or even the inability to maintain any kind of usable SATCOM link. By proactively detecting the interference and relocating the affected users to alternate spectrum, the user’s throughput and link stability were ensured.
