Wideband FM Telemetry Application

Abstract

A Wideband FM Telemetry System was developed by Veda Incorporated and Boeing Commercial Airplane. This system supports Boeing 777 flight testing and will support future Boeing test efforts. This is an upgrade to the system previously used by Boeing for testing other planes. The design interfaces to the new Boeing Data Acquisition and Analysis systems and provides 15 Megabits per second Telemetry at ranges up to 180 miles. This paper provides details regarding the following design and integration issues: o) RF Transmitter Design o) RF Receivers o) Airborne Antenna o) Ground Based Antenna o) Data Interfaces o) System Performance o) Problems / Solutions
