ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper describes a telemetry system developed for the EA-18G Flight Test program. The
program requires transmission of a number of data streams, in IRIG-106 Chapter 4 PCM, Chapter 8
Mux-All 1553, Ethernet, and Fibre Channel formats. The initial requested data rate was in excess of
30 Mbits/sec. The telemetry system must operate at a range up to about 120 miles, at several test
ranges, and with several different aircraft maneuvering configurations. To achieve these
requirements, the Flight Test Instrumentation group at Boeing Integrated Defense Systems in Saint
Louis, developed a telemetry system in conjunction with industry partners and test range customers.
The system transmits two telemetry streams with a total aggregate rate on the order of 20 Mbits/sec.
Each telemetry stream consists of up to four PCM streams, combined in a Teletronics Technology
Corporation (TTC) Miniature Adaptable Real-Time Multiplexer Unit (MARM) data combiner. It
uses Nova Engineering multi-mode transmitters capable of transmitting PCM-FM or Shaped Offset
Quadrature Phase Shift Keying (SOQPSK). The transmitter also provides Turbo-Product Code
(TPC) Forward Error Correction (FEC) to enhance range and improve link performance. Data
collection units purchased from outside vendors or developed by Saint Louis Flight Test
Instrumentation, translate Ethernet and Fibre Channel information into traditional PCM streams. A
Boeing Flight Test Instrumentation developed control system provides flexible selection of streams
to be combined into each telemetry stream, and functional control of antenna selection and
transmitter operation.
