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
