Global Navigation Satellite System has become part of our everyday life and our dependence on it has been increasing though various fields including aviation. The GNSS signal transmitted by satellites is being received as a weak signal, therefore it is susceptible to interferences. A several situations of GNSS interference recently occurred in the real operation causing the limitation of using procedures based on satellite navigation. In most cases, the source of the interference is a jammer placed in a lorry which is located on a road or a car park around an airport. Furthermore, there may be intentionally transmitted jamming signals for disabling the position determination of military vehicles in war zones. There is a need to ensure the alternative navigation system for situations of GNSS signal unavailability, as well as to ensure the time synchronization. A several concepts of alternative systems have already been designed, however, none of them was determined the global alternative GNSS backup system. The project concerns with validation of designed concepts from the sight of appropriate solution for needs of the Czech Republic. Moreover, it aims to create an original model for position determination based on position information exchange among aircraft. This model enables solution for position calculation outside line of sight areas of the terrestrial stations within the alternative concepts.

Engine monitoring and a following operational data analysis is processed by airliners by default. The main reason for the data collection and analysis is to optimize an engine operation. Operators of small aircraft have noticed a high level of the operational effectivity achieved by airliners. It is very expensive to operate an aircraft engine not only for large commercial aircraft but also for small aircraft engines. Therefore, it is needed to respond to the situation and to focus on a data diagnostics by the small engines. The main purpose of this project is to optimise operation of commuter aircraft based on the engine monitoring system and the data analysis. The project is aimed at an establishment of a functional commuter aircraft model allowing a definition of a real-time technical condition of small engines, as well as of remaining engine time resources till overhaul. This enables an effective engine maintenance planning and a TBO (Time Between Overhaul) extension.

The project focuses on evaluation of the recovery of usable meteorological data from secondary surveillance radar responses to use them as input into meteorology. All aircrafts in flight shall broadcast via ADS-B device information about the flight. Part of these data can be used as a source of information for meteorological calculations and methods. The aim of the project is to evaluate the possibilities of data obtaining from aircrafts and to cross check the usability of these data with radiosonding used in meteorology today.

The research assignment "Use of ADS-B messages as a GNSS interference indicator" responds to the demand for GNSS signal interference detection. Civil aviation uses the GNSS signal as the primary source for position and time information. Following the planned use of ADS-B within the SESAR and NextGen projects, the GNSS signal will become completely dominant. Due to the fact that civil aviation uses an unprotected signal, there is an increasing threat of interference. Existing means of identifying GNSS signal interference are limited to terrestrial local monitoring, which is very limited in aviation. The research brings a new concept of interference identification by analyzing ADS-B signal transmitted by flying planes. The method is based on the hypothesis that when the aircraft moves from an undisturbed area to an area with interference, the parameters that describe the quality of the surveillance information in the ADS-B messages. Software to capture these changes could be an indicator of a disturbed area. Due to the ADS-B signal range, it would be possible to monitor large areas in hundreds of kilometers. Identifying the disturbed areas would provide rapid information to relevant stakeholders.

Safety at uncontrolled airports with Aerodrome Flight Information Service (AFIS) is limited by an absence of supportive systems for AFIS officers. With a growing affordability of technical tools, there is an opportunity to use technologically advanced systems in order to reduce AFIS officers' workload and thus increase the safety. Absence of legislative support and restrained attitude of uncontrolled airports lead to the lack of modern equipment needed to meet the requirements of the constantly rising air traffic. Usage of low-cost surveillance systems in combination with modern tracking methods brings new possibilities of using the surveillance information at smaller airports. Implementation of new systems which do not have to meet the strict certification criterions required from air traffic control systems may create the risk that the officer will move his attention from the aerodrome traffic zone to inaccurate position information displayed on the screen. To reduce this and other risks, the proposal of graphical user interface must be considered with regards to the AFIS needs. The surveillance information used to automate some processes will dramatically decrease the AFIS officer's workload and will allow him/her to concentrate on the critical tasks.
