Comtech and RaySat to Provide On-The-Move Solutions

TEMPE, Ariz., Feb. 20, 2007/Satnews Daily/ ― Comtech EF Data Corporation has entered into a collaboration agreement with RaySat Antenna Systems, LLC to provide mobility and communications on-the-move solutions.

The agreement entails interoperability testing of Comtech EF Data's CDM-570/L Satellite Modem and Vipersat Management System with RaySat Antenna Systems' StealthRay. The StealthRay consists of a low profile, vehicle roof-mounted array antenna connected to a controller and a satellite modem inside the vehicle. It is designed to provide communications for vehicles on-the-move.

RaySat Antenna Systems' core platform is the StealthRay Ku-Band antenna system that automatically searches for and acquires the designated satellite signal and maintains pointing via automatic tracking and control of azimuth, elevation and polarization angles while the vehicle is in motion.

Modems are IP-enabled, offer flexible interfaces and support a variety of forward error correction and modulation schemes. The advanced features enable significant bandwidth savings, improve transmission quality and increase control of bandwidth provisioning. Comtech EF Data's feature rich bandwidth and capacity management product, Vipersat Management System (VMS), integrates with the CDM-570/L to provide a seamless IP-based infrastructure for satellite networking.

The solution is based on dynamically managed Single Carrier Per Channel (dSCPC) and

automatic application switching technologies. Bandwidth on-demand is facilitated and all aspects of the satellite network can be configured, controlled and monitored by VMS.

RaySat is a manufacturer and supplier of in-motion, low profile phased-array satellite antennas. Based in Vienna, Virginia, the company focuses on the government, military, enterprise and railway industries. Comtech manufactures a spectrum of satellite communications products, including satellite modems, bandwidth and capacity management and TCP/IP Performance Enhancement Proxies.
