PANSA shows satellite future of air navigation

zdj

On 14th and 15th March, 2011 in Katowice, Kraków and Mielec, Polish Air Navigation Services Agency conducts flights approaches with vertical guidance APV I. Experimental flights and landings will be useful in the development of APV procedures for Katowice, Mielec, Warszawa and Gdańsk.

On 14th March, 2011 at International Katowice Airport in Pyrzowice, representatives of Ministry of Infrastructure, Civil Aviation Office and ESSP - European Satellite Service Provider (institution which, on behalf of the European Commission manages EGNOS), observed first in Poland approach with horizontal guidance with usage of GNSS signal, performed by an aircraft Royal-Star Aero from Mielec Aviation School.

First in Poland experimental flights and approaches with vertical guidance APV I with usage of GNSS signal as part of HEDGE and EGNOS APV programs was carried out by Piper PA-34 Seneca II Royal-Star equipped with Garmin GNS430W certified receiver.

Approach with vertical guidance APV I is an non-precise procedure, in which pilot receives information about plane’s location based on the calculations of on-board devices using data from GPS signal improved by amendments from geostationary satellites of European EGNOS system.

Thanks to EGNOS system, on-board computer can show the accurate path of approach in both the horizontal and vertical plane. The accuracy of the horizontal is the same as in category I ILS, while the accuracy of the vertical is slightly worse than the category I ILS.

On March 2, 2011 EGNOS received the Safety of Life status, which confirms the safe use of the system in aviation.

- GNSS generates information for the pilot which is similar to expensive ILS system. - says Krzysztof Banaszek, President of PANSA.
- The main advantage of the EGNOS APV approach is the low cost of providing air navigation services. This kind of approach does not require expensive investments in ground navigational aids infrastructure, nor raises the cost of its maintenance. - says Krzysztof Banaszek - President of PANSA.

EGNOS: FREE SATELLITE SUPPORT SYSTEM

The official start of European Geostationary Navigation Overlay Service (EGNOS) operations was launched by the European Commission on 1 October 2009. EGNOS is Europe’s contribution to the development of global navigation satellite system GNSS. EGNOS is freely available for both institutions and individuals. Thanks to EGNOS accuracy of satellite navigation in Europe will increase. GPS system which was used so far had a margin of error of 10 meters which now will be reduced to 2 meters. According to European Commission new system will be useful in wide range of branches f.e. in agriculture and transport. After gaining appropriate certification system would be able for usage also in air transport.

System was created with use of transponders placed on three geostationary satellites. Its range covers the territories of most European countries. In the future, EGNOS is expected to extend its geographical coverage outside Europe in the areas such as North Africa. The European Commission is committed to long-term financing of the EGNOS.

Polish Air Navigation Services Agency is actively working to implement EGNOS in Eastern European countries and participates in EU projects related to it.

“EGNOS Introduction to The European Eastern Region” and “HEDGE” „Helicopters Deploy GNSS in Europe” are international projects in which, with the cooperation of companies from several European countries: England, Spain, France, Greece, Switzerland, the Polish and the Czech Republic, landing procedure based on EGNOS satellite navigation system will be implemented at the airports in Katowice and Mielec. For this purpose, the small aircraft aviation (general aviation) will be used. Projects are to show whether the use of satellite navigation for air operations complies with ICAO standards.
