TelemetryTelemetry is a communication process by which measurements and other data are collected at remote or inaccessible locations and transmitted to receiving equipment for monitoring. It is highly automated and is usually performed to monitor environmental conditions or equipment parameters. The term telemetry commonly refers to wireless data transfer mechanisms (e.g., using radio, ultrasonic, or infrared systems). It also includes data transferred over other media such as a telephone or computer network, an optical link, or other wired communications. A set of measuring instruments, an encoder that translates the instrument's readings into analog or digital signals, a modulator, and a wireless transmitter with an antenna makes up a telemetry transmitter. A telemetry receiver consists of a set of radio frequency (RF) amplifiers, an antenna, a demodulator, and recording devices. You can use a computer to process and store the information you receive. Uses: Telemetry is used with mobile robots, satellites, and space probes. It is used in manned spacecraft, such as the Space Shuttle, the International Space Station (ISS), and the Hubble Space Telescope (HST). To monitor the physical condition of astronauts and ensure that a suitable working environment is maintained for them, telemetry is vital. Wireless telemetry systems take measurements in locations that may be distant, moving or dangerous and deliver the result directly to you, at an affordable price. useful information. Rotating telemetry systems, measurement and control of rolling things. They report data such as temperature, pressure, torque or other information from a rotating object, such as a shaft, rotor or wheel wirelessly. The pair's telemetry systems turn a difficult measurement...... center of paper...... ion. However, the most common definition of digital communication considers both passband and baseband to be digital transmission. The transmitted data may be in digital format, for example from data sources such as a computer, etc. or they can be in analog form like a video. /audio signal which is then digitized into a bit stream using modulation techniques or source coding schemes such as data compression and analog-to-digital conversion. Modern modulation techniques include pulse width and pulse code modulation. The codec equipment helps to do the work of encoding and decoding the source. Common examples of communication channels are fiber optics, copper wires, computer buses, and wireless communication. The data to be transmitted is represented as electromagnetic signals, for example infrared signals, electrical voltage, microwaves, etc.
