Comtech Telecommunications Corp. has introduced the Comtech COMET, the world’s smallest over-the-horizon (“OTH”) microwave troposcatter terminal. In connection with the introduction, Comtech received an initial contract award for production terminals from ADS, Inc. to be used by a U.S. Military end-customer. The Comtech COMET is a medium range (up to 60 km), high bandwidth (up to 210Mb/s), communications terminal that fills a void in distances that have long been desired by tactical communications planners. It uniquely addresses the SOCOM community’s concern of low probability of intercept and low probability of detection (“LPI/LPD”), while providing high reliability, mission essential communications.

The foundation of the Comtech COMET is the CS67PLUS Troposcatter Radio, the first software-defined adaptive troposcatter radio packaged in a compact IP66 sealed module, capable of all-weather operations in harsh climates. The radio is MIL-STD 461 EMI compliant and MIL-STD 810G environmentally compliant. The radio uses diversity combining receivers to detect and recover signals below -100dBm in a Rayleigh fading environment. Other key features include Adaptive Code Modulation (“ACM”) and Automatic Link Power Control (“ALPC”) to further reduce RF signature and enhance throughput. Given that the CS67PLUS is frequency agile between 1.8GHz and 6GHz, the Comtech COMET can be adapted for use in frequency bands within this range.
