    Construction of an Aircraft-Type UAV for Flight Along a Given Trajectory in the Automatic Mode
    (International Journal of Emerging Trends in Engineering Research, 2020) Myasischev, Olexander; Lienkov, Serhii; Banzak, Oksana; Komarova, Larysa; Lytvynenko, Nataliia; Miroshnichenko, Oleg
    A budget (up to $100) unmanned aerial vehicle (UAV) of an aircraft type based on the OMNIBUSF4V3 flight controller with an STM32F405 microcontroller is developed in the article. The created aircraft performs the following flight modes: the holding altitude and position, the automatic return to the takeoff point on command from the control panel or in case of loss of communication with it, the automatic flight along a given trajectory. The possibility of the flying along the points of the designed aircraft with the firmware INAV ver.2.5.0 without using a barometer and magnetometer, that are necessary for the rotary UAV to perform a similar task, is shown. Using the Blackbox INAV 2.5.0 toolkit and the Google Earth Pro service, the real flight path of the aircraft, speed parameters, and flight altitude according to the readings of the GPS receiver were established. The heights and speeds of the aircraft passing the flight points have been experimentally determined. Their close correspondence was established to those values, that were programmatically entered into the aircraft flight controller before launch. The correspondence was established between the real flight path of the aircraft and the one entered into the flight controller using the configurator. The constructed aircraft can be used to perform photo and video surveys of the terrain in automatic mode with the route length of 6-8 km, using a lithium polymer battery with a capacity of 1800-2200 mAh.

    Use of rescue mode for UAV on the basis of STM32 microcontrollers
    (International Journal of Advanced Trends in Computer Science and Engineering, 2020) Myasischev, Alexander; Lienkov, Serhii; Banzak, Oksana; Husak, Yurii; Starynski, Ivan
    The practical possibility of a guaranteed return of budget unmanned aerial vehicles (UAV) to area of the starting point in event of loss radio communication with a video camera or control panel is considered. In this regard, an experimental model of a flying wing with wingspan of 1000 mm and a flight weight of up to 500 g was built, on which a flight controller SPRacingF3 based on the STM32F303 microcontroller with a GPS receiver and a directional video camera was installed to provide FTP flights. Based on INAV firmware, main attention was paid to setting flight modes NAV RTH, NAV FAILSAFE to ensure a guaranteed return. The practical possibility of using GPS Rescue mode for Betaflight firmware to return quadrocopter to a point close in take-off coordinates was also considered. In this regard, an experimental prototype was built with a 250mm frame, but with which OMNIBUSF4V3 flight controller was installed based on STM32F405 microcontroller with a GPS receiver and a heading video camera for FTP flights. During flight tests, it was shown that GPS Rescue mode allows you to return UAV to the launch zone, subject to the settings presented in the work on the assembled quadcopter. When performing GPS Rescue mode, an important condition is the stable connection of GPS receiver with the number of satellites not less than those installed when setting up the firmware. It is established that for the return of UAV of the considered types it is not necessary to use a barometer and magnetometer, functions of which can be performed by GPS receiver
