1.0 Introduction
The vehicle system control using telemetry application is all about using a radio wave to control and activate certain events such as the car horn, car head light, car ignition (starter) and car air conditioner etc.
This is achieved by using various tone frequencies by using an encoder via a radio frequency transmitter (low power) that provides the carrier frequency for these tones.
At the receiver end demultiplexing and decoding of these tone takes place via a detector/receiver stage. The output of the encoder is used to turn on a relay switch, which inturn connects power source to either the car engine, horn or lamp etc.
The application of thus project include space exploration, where lunar vehicles are controlled from earth station by using satellite as the medium of transfer of signals.
In the military warfare, unmanned air crafts, missiles and even armoured tanks are controlled these days by using the pinaple of telemetry applications. Other areas include GSM, where a subscriber has the total control of his telephone calls conversation through the BTS (Base Transmission or Transceiver Station). Its application are so vast and large that they are too numerous to mention.
