Indra improves Mongolian air traffic management MADRID, July 24 (UPI) -- Indra, a Spanish consultancy and technology firm, is helping Mongolia improve airspace surveillance and air traffic control. Under an award from the Mongolian Civil Aviation Authority, the company will install its ADS-B systems at various points in the country. The automatic dependent surveillance-broadcast will strengthen the visibility of air movements and complement the Mode S MSSR radar surveillance systems the company previously deployed in Mongolia and which are currently in service. "The implementation of these new systems will improve the fluidity of air traffic in a zone crossed by the one of the most important routes linking Europe and Asia," Indra said. They will also improve the control of aircraft approaches to the airport serving the country's capital, Ulaanbaatar. Neither Indra nor Mongolia provided details on the number of ADS-B systems to be deployed in the country. A delivery schedule and value of the contract were also not revealed.
