Washington, January 31: Thousands have lost their life in airplane crashes. To make their travel safer and to track the flight NASA has come up with new radio which will help traffic controllers see the location of every plane. NASA's new space-based radio system can track aircraft even if it is crossing oceans which would make air travel safer and ensure that flights can be quickly located in case of mishaps.NASA's powerful radio communications network allows us to receive data such as pictures of cryovolcanoes on Pluto - or tweets from astronauts aboard the International Space Station (ISS). Likewise the radio will allow us to track the location of the travelling plane.

It can also be upgraded to work better with future missions or to enhance performance, just by adding new software said Kacpura.

NASA worked with US-based technology company Harris Corporation to design and develop a new reconfigurable, higher-bandwidth radio. The radios will be used to create the first space-based global air traffic control system.

Initially airplanes have relied on radar surveillance via land-based radar stations. This was limited as it wouldn’t allow us to trace the flights especially over oceans where air traffic controllers have no real-time information. Pilots file detailed flight plans and are required to remain within prescribed lanes at different altitudes so air traffic controllers can estimate where they are and work to ensure there are no mid-air collisions.

This new radios are programmed to receive signals from new airplane transceivers called ADS-B, which automatically send out a flight's number, location, heading and other details.

"Within seconds you can keep track of all the aircraft in the world," said Harris systems engineer Jeff Anderson. With real-time global tracking, planes can fly with less space between them and take more direct routes.

"It tremendously improves public safety and potentially saves a lot of fuel costs, because you no longer have to remain in the particular airline traffic lanes," Anderson said. If something goes wrong, search and rescue teams will have detailed information on where the plane was last spotted. The system may also be used to similarly track ships.
