New-Generation Small-Size Solid-State Wave Gyroscope for Strapdown Inertial Navigation Systems of Unmanned Aerial Vehicle

The tasks set for unmanned aerial vehicles (UAV) can only be solved provided that the latter are equipped with modern airborne navigation and control systems. Nowadays orientation, navigation and control systems for multipurpose pilotless aircraft are based on small-size dynamically-tuned gyros (DTG), ring laser gyros (RLG), fiber optic gyros (FOG) as well as modern microelectromechanical gyros (MEMS gyroscopes). The flight test results have clearly shown that it is impossible to create modern commercial UAV systems capable of providing effective and reliable online monitoring in all-weather conditions without an onboard control complex with an accurate high-precision strapdown inertial navigation system (SINS).
