The base of all these systems is the collection of satellites in space, which have changed the whole system of airplane and air traffic tracking. The satellite tracking method overcomes several hurdles that are faced by ATCs. Satellite based tracking systems utilize satellite transmitters, receptors, decoders, 2-way communication antennas and microprocessors, working in sync with satellite stations. The paramount features of this technique are exhaustive graphic images, contour analysis, etc., which provide flawless flight tracking. The laser tracking technique, a comparatively new technique, uses stereo imaging coupled with laser beam tracking. This method is not in full-fledged use at present but could turn out to be a consistent system in coming times.
All said and done, an excellent tracking technique remains the one which employs the best of all the worlds. One such technique, as per the experts, is the union of satellite-based tracking and GPS (global positioning system). This technique determines the geographical position of the flight using GPS when the flight is ready to land. The role of the satellite is to exhibit a vivid light right from the launch point to the destination displaying real-time position of the plane. In order to provide continual details, this page needs to be re-loaded continuously. This method makes for easy calculation of delays. It is predicted that this will result in a highly sophisticated method that will give accurate and trusted flight details.
All of the above mentioned methods are used to track airplanes, maintain coordination between them, and thus control air traffic. It is because of these air traffic tracking systems that airplanes are known as the safest option for traveling. Moreover, the rising unpredictability of nature due to global warming and threats due to increased terrorism also demand sound air traffic control systems for the utmost safety of airplanes and passengers.
