Kratos Defense & Security Solutions has announced that its SAT Corporation (SAT) subsidiary has released SigX Protect, a patent-pending radio frequency (RF) signal protection product that can be configured to automatically cancel RF interference in real time with no human intervention. Using this technology, operators will be able to eliminate signal interference, thereby improving customer service quality, protecting revenue and assuring mission goals. SigX Protect works by automatically detecting and characterizing interfering signals by phase, amplitude and frequency. It then creates a cancelling signal to remove the interference and preserve the integrity of the protected link. SigX Protect employs a technique called blind separation that requires equipment only on the receiving end of the communications path and allows SigX Protect to characterize and cancel an interfering signal with no prior knowledge of the source or location of the interference. This technology can be installed directly in the communications chain to reduce any potential delay or latency in the communications signal.
Until SigX Protect, satellite operators and communications providers were largely limited to solutions to monitor, detect and locate interference; however, actually cancelling the interference usually required contacting the interferer for assistance—if known and if cooperative. Expensive, controlled technologies such as frequency hopping waveforms and advanced channelizers on the satellite have been available for government and defense applications, but these come with significant cost and operational complexity. In contrast, SigX Protect works with all existing and new satellites, incurs no added bandwidth costs and provides dedicated protection with no impact on operations.
SigX Protect will be on display at the Satellite 2015, March 16-18, 2015, Walter E. Washington Convention Center, Washington DC.
