Remotely Piloted Airplane Systems
- Department of Aerospace Engineering
This course focuses on the modern concept of aircraft avionics, its design and development strategies. These systems are composed from individual HW blocks that exchange data through high-speed data busses. The existing regulatory standards and airspace sharing define requirements for the accuracy, reliability and functionality of electronic systems even in the event of a failure. The objective of the course is to present details about requirements for safety-critical multi-sensor systems, methods of data processing from overdefined systems, methods of fault detection, selection of primary computing and control system in parallel architectures, bus technology and methods of testing / airworthiness of aerospace instruments.
- Syllabus of lectures:

- Study Objective:
The subject will introduce students into the technology used on the unmanned aerial vehicles with special attention to sensors, the required precision for the safe flight and the ability to maintain stabilisation. These topics will be covered in details: calibration issues and specific problems with inertial sensors, magnetometer and data fusion algorithms. The topics discussed will be solved in the exercises in the individual tasks on simplified examples.
