DESIGN OF AUTO NAVIGATION SYSTEM OF UAV(UNMANNED AERIAL VEHICLE) WHICH REDUCES AN ERROR VALUE BY THE CONTROL OF A SERVO MOTOR

摘要

PURPOSE: A design of auto navigation system of UAV(Unmanned Aerial Vehicle) is provided to reduce the generation of an interrupt using RTOS(Real-Time Operating System). ;CONSTITUTION: A design of auto navigation system of UAV(Unmanned Aerial Vehicle) comprises a power supply unit, a DSP(Digital Signal Processor), and a switching module. The power supply unit divides into a power source of a manual flying system and a power source of an autopilot system. Although one among devices is out of order or the power source of a system does not supply to the device, the manual mode is processed to guide safe landing. DSP-A transmits the data operation result of a sensor and GPS(Global Positioning System) to DSP-B through a SCI(Serial Communication Interface). The switching module selectively converts a DSP signal and RC(Radio Control) receiver signal by using AVR(Automatic Voltage Regulator) chips.;COPYRIGHT KIPO 2011
