Rockwell Collins certifies first simultaneous dual HSD channel and Aero channel system

CEDAR RAPIDS, Iowa (September 25, 2003) - With the installation of dual Collins HST-900 transceivers to a Collins SAT-906 SATCOM system, a Falcon 900EX becomes the first business aircraft in the world to operate simultaneous dual high-speed data (HSD) channels and Aero channels. The system has received Federal Aviation Administration (FAA) Supplemental Type Certification (STC).

"We are building on our successes by maximizing available technologies," said Dennis Helgeson, vice president and general manager of Business and Regional Systems for Rockwell Collins. "By bonding the channels, we are able to provide 128 Kbps data rates, pushing this technology to the next level."

The Collins HST-900 enables enhanced passenger connectivity, including access to e-mail and the Internet while in flight. Designed as a companion to the Collins SAT-906 satellite communications system, the HST-900 provides high-speed connectivity using Inmarsat's Swift64 service.

The STC permits the use of Aero safety services in the flight deck and simultaneous voice and high-speed data channels in the cabin. This capability is made possible through a Rockwell Collins proprietary software management system that ensures the flight deck maintains its priority and pre-emptive receipt of essential communications. The management system also validates frequency assignments to ensure there is no potential interference with GPS frequencies.

The HST-900 system enables simultaneous use of high-speed data and Aero H/H+ services through a common 60-watt high power amplifier and high-gain antenna. Once installed, the HST-900 can be upgraded for new generations of Inmarsat high-speed data services without affecting the SAT-906 functionality.

The installation includes a Collins Wireless LAN Unit (WLU), which supports the IEEE 802.11b standard and is DO-160D certified. The WLU simplifies installation, since it does not require routing of wires throughout the aircraft cabin. This enables laptop users to gain access without hard wired connections.
