The Spanish company Aistech Space presented its air traffic monitoring and control system via satellite, within the framework of the World ATM Congress 2019 that was held from March 12 to 14 in Madrid.
Since the deployment of its constellation will begin at the end of 2018, the company is able to monitor with satellites the position of aircraft that fly over global airspace with special monitoring of areas where there is no radar-ground coverage. These areas represent more than 70% of the globe and range from much of the oceans and seas to large remote land areas and unpopulated continental areas without the necessary infrastructure.
The system is based on ADS-B data emitted by aircraft and collected by satellite, providing a large volume of information for a large number of companies and institutions related to space and air navigation. Since the beginning of this year, Aistech Space has already provided data collected by satellite to various companies and organizations in the aviation sector.
The ADS-B system will be mandatory from 2020 according to the ICAO (International Civil Aviation Organization). This system will complement current ground-based radar tracking systems whose range is limited as they do not have global coverage. Due to this lack of coverage, it is not possible to know with certainty what was the real position of an aircraft. This information has represented an emergency situation, an inconvenience in its subsequent location.
The areas so far called “dark areas” and where some of the main air routes run, will soon cease to be so, being able to know at all times “who” and “exact position” that is flying over any part of the planet.
