The use of and dependence on technology has grown tremendously in the last two decades, and with it comes distinct responsibilities and new problems that must be addressed. SAIT track is used for the challenges of personnel signal verification, identification and generation. This project and implimentation discusses the available and emerging techniques of SAIT track. In this project and implimentation we can control or track dish antenna towards satellite using PC parallel port, using turbo c coding. The dish (sensor attached) can rotate and cover total orbit of 360 degree of angle so that it can receive signal from each direction (north, south, east and west) for these purposes we use steeper motor. In our project and implimentation for demo purpose we use fixed infrared receiver attached to the disc. This receiver response only to infrared signal and it is directional sensor. On the other hand we make infrared transmitter. So that we transmit a frequency in particular angle and when rotating disc comes in that direction it receives the signal and gives indication of catch location on PC. It deals with the following parts:
It can be detected at a small distance.
Ultrasonic is expensive.
Laser is a single beam from source to receiver.
There should be accurate alignment.
Interface circuit is used to interface the motor with the computer's parallel port; we will build up a circuit through the use of TTL device to get a supply voltage of 12V. This is because, our stepper motor used is a 12V one and the parallel port gives us only 5V.
