Development of an integrated system of onboard equipment to provide trajectory control of a small unmanned aerial vehicle

摘要

The report discusses the tasks associated with the development of a microprocessor-based digital system for measuring the flight altitude of an unmanned aerial vehicle (UAV), that meets all modern trends and requirements for the development of world aviation instrumentation. For a small UAV, you can successfully integrate two altitude measurement channels: a satellite navigation system and an accelerometer-based inertial system. This data processing algorithm, despite its simplicity, is very effective. In addition, the implementation of an on-board instrument system that implements it is an excellent educational task both for the development of computer models in the MatLab and Labview environment, and for the manufacture of a working prototype using inexpensive available radio components. These tasks were solved mainly for educational, research and educational purposes at the St. Petersburg State University of Aerospace Instrumentation with a wide involvement of students, including foreign ones. So in 2016, a student from Germany, Muhammad Kkhalaf, underwent an internship at SUAI, who has the opportunity to test prototypes of the equipment being developed during test flights at different working altitudes, performed on a personal light-engine Fizler-156 aircraft. The test flights confirmed the specified accuracy of the altitude measurement obtained by computer simulation.
