Abstract
The paper analyzes the possibility of an automatic low-altitude flight of an unmanned helicopter in terrain following mode in case of interference in the satellite navigation channel. We show that this can be done by using an onboard integrated system that ensures the accuracy of navigation (standard deviation) of 3 meters in plan, 10 meters in height, and 0.5° in orientation angle. These parameters are achieved by integrating the data received from micromechanical inertial sensors and multichannel GLONASS/GPS receiver with an anti-nonmodulated interference system.
