- any of certain devices or attachments for determining distances by measuring the angle subtending a known distance.
- Electricity. the complete measuring, transmitting, and receiving apparatus for indicating, recording, or integrating at a distance, by electrical translating means, the value of a quantity.
verb (used with object)
- to transmit (radio signals, data, etc.) automatically and at a distance, as between a ground station and an artificial satellite, space probe, or the like, especially in order to record information, operate guidance apparatus, etc.
verb (used without object)
- to telemeter radio signals, data, etc.
- the use of radio waves, telephone lines, etc, to transmit the readings of measuring instruments to a device on which the readings can be indicated or recordedSee also radiotelemetry
- the measurement of linear distance using a tellurometer
- any device for recording or measuring a distant event and transmitting the data to a receiver or observer
- any device or apparatus used to measure a distance without directly comparing it with a measuring rod, etc, esp one that depends on the measurement of angles
- (tr) to obtain and transmit (data) from a distant source, esp from a spacecraft
n.1860, a rangefinder for surveying and artillery, from French télémètre (1852), from télé- “far” (see tele-) + mètre “meter” (see -meter). Used from 1953 for a pay-as-you-watch TV system with a coin box attached to the set. n.
- The science and technology of automatic measurement and transmission of data by radio or other means from remote sources to receiving stations for recording and analysis.
- The measurement of data at a remote source and transmission of the data (typically by radio) to a monitoring station. Telemetry is used, for example, to track the movements of wild animals that have been tagged with radio transmitters, and to transmit meteorological data from weather balloons to weather stations.
Automatic measurement and transmission of data or information by such means as wire or (more commonly today) microwave relays from the source to a distant receiver.
