Comtech EF Data Works with Raysat Antenna to Provide Communications on-the-Move Solutions

TEMPE, Arizona, March 14, 2007/Satnews Daily/ — Comtech EF Data Corp. has entered into a collaboration agreement with RaySat Antenna Systems, LLC for the interoperability testing of Comtech’s CDM-570/L Satellite Modem and Vipersat Management System with RaySat’s StealthRay to provide mobility and communications on-the-move solutions.

RaySat Antenna Systems’ core platform is the StealthRay Ku-Band antenna system which consists of a low profile, vehicle roof-mounted array antenna connected to a controller and a satellite modem inside the vehicle. It was designed to provide communications for vehicles on-the-move. The antenna system 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.

"As a result of this collaboration agreement, in-motion satellite communications in remote areas, en route or on site are all achievable for vehicles equipped with StealthRay and Vipersat-enabled IP modems," said Ilan Kaplan, president, RaySat.

Ideal for optimizing satellite communications, Comtech EF Data said its CDM-570/L Satellite Modems are IP-enabled, offer superior performance and flexible interfaces, and support a variety of forward error correction and modulation schemes. It added its advanced features enable significant bandwidth savings, improve transmission quality and increase control of bandwidth provisioning.

Comtech EF Data explained its 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.

"The unique combination of 5/16 Turbo Product Coding forward error correction, BPSK modulation and the extremely fast acquisition time of the CDM-570/L Satellite Modems enable the StealthRay to provide reliable, high data rate communications for mobile endpoints," said Frederick Morris, general manager of Vipersat Network Products Group, of Comtech EF Data.
