9 September 2004
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
Vibrations
Velocities
Flows
Pressures
Temperatures
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 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“)

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
