Basically what is telemetry?
Telemetry is a science where electronic devices are used to record or measure a distant event and transmit the data to a receiver. Telemetry thus makes use of many devices and equipment to carry out its processes.
Telemetry being more a method of measurement than a strict procedure in itself, many instances are touched upon by this ‘science.’ Meteorologists use telemetry to record inaccessible data like the weather conditions high in the air. In such a case, thermometers and humidity scales would be part of the telemetry equipment. A core feature of the procedure would be the transmitter that is essential to telemetry. The transmitter ensures that the data collected is received by those requesting this same data. In the case of a weather balloon, meteorologists would have no convenient way of retrieving the data from the balloon at those specific parameters that they need them. If a transmitter hadn’t conveyed the temperature at, say, 500 feet, by the time the balloon would be back on the ground, it would no longer give the relevant data.
Space exploration is another instance where telemetry is used. Scientists use telemetry to gather data on far reaches of the solar system. For example, probes sent to Mars rely on telemetry equipment to transmit the information gathered back to NASA on Earth.
Geology and marine biology are other areas where this methodology and telemetry equipment come in handy. Hence, information can be gathered at ocean depths where humans cannot go. Or data about the core of the Earth can be transmitted back to geologists, helping to shed more light on our planet.
