  1. AERONAUTICAL TELEMETRY Darrell Ernst Jean-Claude Ghnassia Gerhard Mayer 9 September 2004

  2. What You Will See and Hear • A video describing how aerospace vehicles are tested, what telemetry is and how telemetry is used • A brief view of how telemetry is used around the world • A brief description of how technology is used to send the telemetry measurement data to the ground station in the most spectrally efficient manner possible

  3. What is Telemetry? • Telemetry : The process ofmeasuring at a distance. • Aeronautical telemetry: Theprocess of makingmeasurements on an aeronautical vehicleand sending those measurements to adistant locationfor analysis Vibrations Velocities Flows Temperatures Pressures If it is ORANGE it is flight test measurement

  4. Time for the Cinema! Aeronautical Telemetry

  5. Dr. Gerhard Mayer

  6. Science and Telemetry Goes Global…Local changes of environmental parameters have a world-wide impactWide-area telemetry networks needed to collect data from e.g. remote field stations, balloons, buoys, sounding rockets, UAVSpecific ranges for launching, science observations and data collection worldwide available

  7. Sounding rocket launch sites Region 1 Kiruna, Sweden Formosa Bay, Kenya Coronie, Surinam Biscarosse, France Salto di Quirra, Sardinia Aberporth, Wales Zingst, Germany Emba, Kazakhstan Region 3 Anna Plains, Australia Chandapore, India Sonmiani, Pakistan Chiu Peng, Taiwan Shuang Chenghzi, China Changwon, S.Korea Malute, Pakistan Wake, Marshall Islands Region 2 Tortuguero, Puerto Rico Punta Lobos, Peru Ft.Yukon, Alaska Nanoose Bay, Canada Mar Chiquita, Argentina Wallops, USA Stromfjord, Greenland Poker Flat, Alaska

  8. Telemetry Inevitable in Global Missions Platforms on balloon, sounding rocket and UAV required for In situ-measurements & callibration of satellite and ground borne instruments Examples of important disciplines : • Geophysics Atmosphere, Land , Sea, Ice Research • Biology Animal behaviour & wildlife research • Remote Medical Supervision patient monitoring e.g. at expeditions („bush telemetry“)

  9. Science Missions Requiring Wideband TM Existing LEO-satellite data collection platforms only for narrow band data transmission (e.g. Argos, Orbcomm) available Onboard storage capacity limited by space and weight, data compression & reduction of science data onboard critical Data required on ground mostly in near-realtime Therefore: High-resolution science instruments, like imaging sensors, spectrometers, carried as Balloon, Sounding Rocket or UAV- payload need wideband telemetry links to fulfill their future missions
