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

What is Telemetry?Telemetry : The process of measuring at a distance.
Aeronautical telemetry: The process of making measurements on an aeronautical vehicle and sending those measurements to a distant location for analysis
TemperaturesFlows
Vibrations
Velocities
Pressures
If it is ORANGE it is flight test measurement

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

Telemetry Inevitable in Global Missions
Platforms on balloon, sounding rocket and UAV required forIn 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 Supervisionpatient monitoring e.g. at expeditions („bush telemetry“)

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
