Radio indication

Radio indication (or radio indication) is an indication method based on the measurement of the signal received during a radio transmission. During the indication process, the sender sends a signal that can be measured by the receiver. The receiver then receives this signal and calculates its value using an analyzer. This procedure allows you to transmit information about an object, the environment, the state of equipment or a device, without using wired connections. This method is especially useful in environments where traditional means of data transmission do not work, such as in outer space.

The operating principle of radio indication is to use antennas and transceiver devices to transmit and receive signals. Thus, instead of traditional wires and cables, electromagnetic field waves are used to transmit information from the transmitter to the receiver.

A widely used method is radio-measuring the distance between objects, or radio-detector, that is, installing a receiver and two transmitters, the first of which is the final object, and the second is the starting object. The receiver measures the path difference (the time interval between the arrival of the signal from the object and the signal sent by the transmitter) and by comparing the path difference with the known delay of the signal (command) received at a known distance, the distance to the object can be determined using a simple formula.

This method has several advantages over traditional indication methods. Firstly, radio indication allows data to be transmitted over long distances without the need for wires or electrical signals
