ATC Maastricht – February 15, 2006 –  - The Civil Aviation Authority of Mongolia (MCAA) signed an agreement to deploy Rannoch’s Wide Area Multilateration ADS-B technology for en route and approach surveillance across Mongolia.

The airspace above Mongolia has become increasingly busy and complex in recent years as a result of growing traffic between Europe and China, most of which travels over 1,000km through Mongolian airspace.

There is no civil radar surveillance in Mongolia and the MCAA relies on procedural control and appropriate separation to maintain safety in Mongolian airspace.

The recent introduction of polar flights between Asia and the USA has contributed to increased traffic volume and there were nearly 50,000 overflights safely managed by the Mongolian CAA last year.

Recognising the need to implement surveillance to manage the growth in traffic, and maintain safety levels whilst reducing separation, the MCAA was faced with the choice between traditional radar technology or more advanced solutions such as ADS-B or Multilateration. “Rannoch’s Multilateration ADS-B solutions offer greater accuracy, faster update rates, higher availability and better coverage than radar, especially in complex terrain such as Mongolia, and all at a fraction of the cost of traditional radar,” said Russell Hulstrom, Rannoch’s Vice President, International.

“While our solution will also receive and decode all of theADS-B traffic over Mongolia, our active multilateration techniques ensure full fleet coverage without the need for new avionics and also provide MCAA with independent position information to verify any ADS-B data that is received,” he continued.

The multi-phase programme will commence with the immediate deployment of a system in Ulaanbaatar which will provide coverage of important en-route intersection points as well as the approach to Ulaanbaatar International Airport (ULN).

Later expansion of the system could include all of the major cross-country routes and 16 airports in the country.Rannoch is the leader in wide area multilateration ADS-B solutions which have been chosen for approach and en route surveillance by a number of US and Japanese airport authorities, military agencies, and also by Air Navigation Service Providers in Canada, Taiwan, and New Zealand.
