telecommunications Transmission, emission or reception
of signs, signals, writing, images or sounds by wire,
radio, visual or other EM system; abb. telecom.
teleconference Conference between participants linked
by telecom system.
Teleflex Mechanical remote-control systems in which
push/pull commands are transmitted by tube-mounted
cable with complex coiled overlayers [able to drive
toothed wheel].
telegraph Telecom using succession of identical electrical
pulses.
teleguided Not a normal expression; could mean a
missile guided by radio command or by wires.
telematics This word does not appear in normal English
dictionaries. It appears to mean automatic control over
wide areas encompassing several systems.
telemetry Transmission of real-time data by radio link,
telltale
eg from missile to ground station; today invariably digital
and important in RPVs and unmanned reconnaissance
systems. Data can be pressure, velocity, surface angular
position or any other instrument output, or any form of
reconnaissance output. Telemeter is verb; use as noun
arch. Noun is * system or telemetering system.
telemetry intelligence A branch of sigint, involving
analysis of hostile telemetry signals.
teleoperator Robot for performing mechanical tasks
under remote control.
telephone Transmission of sounds, signals or images by
wire or other discrete-path link, eg microwave beam or
optical link using free coherent beam or fibres.
telephone box Figurative enclosure of aircraft whose
energy has decayed in air combat to point where he is low
and slow and has ‘no place to go’.
telephotography Photography of distant objects on
Earth.
telephotometer Visibility meter.
teleprinter Telegraphy with keyed input and printed
written output.
teleprocessing EDP (1) by computer fed by telecom
system.
teleran Television radar air navigation; use of ground
radar to feed airborne TV display.
Telesacs Telematics for safety-critical systems, in particular
co-ordination of ACAS, STCA and precision
navigation (Euret).
telescience Increasing output of space science experiments
by use of Internet and broadband satellite
communications to involve ground-based researchers.
telescope 1 In astronomy, instrument for collecting EM
radiation (esp. light, radio, IR and X-ray) from extraterrestrial
sources.
2 To reduce overall dimensions by folding or, esp.,
linear retraction, eg helicopter rotor.
3 To reduce propeller diameter by cropping tips.
telescoped ammunition Rounds in which the projectile is
carried largely within the case, reducing length and
increasing propellant energy per unit overall volume.
telescope gauge Precision rod sliding in tube and locked
to measured dimension, eg hole diameter, subsequently
measured by micrometer.
telescoping To telescope (2, 3).
telescramble 1 To render telecom, usually telephone,
conversation unintelligible by scrambling.
2 Dedicated telephone cable plugged into aircraft,
especially one armed with NW, waiting on ORP.
teletype US term for teleprinter; hence *-writer; often
capital T (registered name).
television Transmission and reception of real-time
imagery by electronic means. Link usually by radio but
may be any other telecom form, and imagery usually
keyed to sound channel, entire received signal also being
recordable by receiver; abb. TV.
television command See television guidance.
television guidance Command guidance by radio link
sending steering commands from operator watching TV
picture taken by camera in nose of vehicle.
telezygology Technology of smart fasteners.
telint Telemetry intelligence.
telling See track telling.
