Opis:
In the paper the implementation process of commercial flight and navigational controller in own aircraft is shown. The process of autopilot integration were performed for the fixed-wing type of unmanned aerial vehicle designed in high-wing and pull configuration of the drive. The above equipment were integrated and proper software control algorithms were chosen. The correctness of chosen hardware and software solution were verified in ground tests and experimental flights. The PID controllers for longitude and latitude controller channels were selected. The proper deflections of control surfaces and stabilization of roll, pitch and yaw angles were tested. In the next stage operation of telecommunication link and flight stabilization were verified. In the last part of investigations the preliminary control gains and configuration parameters for roll angle control loop were chosen. This enable better behavior of UAV during turns. Also it affected other modes of flight such as loiter (circle around designated point) and auto mode where the plane executed a pre-programmed mission.

Opis:
PRS (Polish Register of Shipping) is an expert institution acting on the international market, that - by conducting business for the benefit of the community - through the formulation of the requirements, survey and issue of the appropriate documents, assists State Administrations, Underwriters and customers in ensuring the safety of people, floating objects, land undertakings, carried cargo and the natural environment. PRS is a body accredited for certification of management systems, as well as a notified body in the European Commission for conducting product conformity assessment procedures with EU directives and regulations, and certify of personnel and processes. Subject and scope of the Publication The Publication defines requirements and procedures of conformity assessment process of Unmanned Aircraft (UA) and the technical possibilities of their use in the maritime economy segment. Purpose of the publication: Defining technical and formal requirements for design, construction and operation of the Unmanned Aircraft (UA), Determining the scope and methodology of conformity assessment process of Unmanned Aircraft (UA), Determining the technical possibilities of using Unmanned Aircraft (UA) in the maritime economy segment. The publication includes the following issues: basic principles and design requirements as well as technical regulations that ensure the design of the Unmanned Aircraft (UA), as a safe product in operation; the scope and methodology of conformity assessment of Unmanned Aircraft (UA); principles and scope of technical supervision over the Unmanned Aircraft (UA), requirements set by PRS in using Unmanned Aircraft (UA) on sea-going ships. The conclusions of the paper: indication of the way to obtain BSP certification, the basis for launching the procedure for developing the NO defence standard for the certification of ships and naval auxiliary units for cooperation with Unmanned Aircraft (UA).

Opis:
Artykuł przedstawia ogólne uwagi związane z tworzeniem systemów sterowania i nawigacji tolerujących uszkodzenia pojawiające się w ich elementach składowych. Główną uwagę zwrócono na uszkodzenia w układach wejścia. Jako przykład omówiono odtwarzanie uszkodzonych sygnałów pomiarowych za pomocą estymat wyznaczanych na drodze analizy modelowania procesów fizycznych zachodzących w rozpatrywanym systemie. Metodę tą zastosowano również do zademonstrowania możliwości wyznaczania zwielokrotnień umożliwiających przeprowadzenie diagnozy systemu.
The paper presents basic remarks about construction of fault tolerant control and navigation systems for UAV. Reliability and safety requirements can be fulfill with usage of redundancies. Presentation of different kinds of avionic redundancies with comments about their usage during fault appearance is an important part of the paper. The main authors' attention is paid to faults in input devices. Their first goal of UAV measurement devices is generating the information of high quality, but the information must be dependable. On the basis of the authors' work experience, the application of signal estimation with remarks about their precision is introduced. After the general information about the troubleshooting in UAV measurement systems, the usage of a complementary filter for calculations of the roll angle is presented. Moreover, two methods of roll angle estimation are given with comments. The comparison of two methods of navigation parameter calculation as the diagnostic method application is also described. The considered applications have specific feature of UAV avionics systems in the presence of faults.
