The Performance of GNSS Services for the Area Navigation Applications of Civil Aviation in CR
Ptáček, Pavel ; Novák,, Andrej (referee) ; Vosecký, Slavomír (referee) ; Kevický, Dušan (advisor)
The dissertation deals with the assessment of navigation performance of GPS/EGNOS system in user position domain. Examination is based on a static signal in space monitoring and evaluation campaign to assess the ability to provide sufficient performance for new navigation procedures. GPS/EGNOS system is the first primary navigation system to be used in the airspace of Czech Republic. The first part describes the benefits of using new procedures, summarizes navigation development and current status. The second part defines components of GPS/EGNOS primary navigation system being analysed and its characteristics with the potential impact on the quality of approach navigation services to be provided and ensured by EGNOS. Subsequently, the methodology for critical evaluation of GPS/EGNOS signal in space navigation performance in position domain to be monitored by of air traffic services was formulated, using new methods for investigation of accuracy, integrity and continuity with the focus on final approach procedures. Simultaneously supporting software for data analysis against performance requirements in position domain was designed. Based on campaigns of static experimental measurements and detailed analysis of combined GPS/EGNOS performance against the demands, the level of performance is analysed, the findings are presented and conclusions are made. In the last part, the usage of permanent geodetic stations for regular evaluation of GNSS performance for civil aviation purposes is designed and verified, and the conclusions based on navigation performance evaluation of observations from all selected station in the Czech Republic.
