KFS-3B integrated control and navigation unit

The KFS-3B flight control and navigation unit consists of a MEMS inertial measurement unit, a GNSS receiver, an atmospheric pressure sensor, and a main controller based on a high-performance ARM. The flight control and navigation unit uses sensor measurements to determine the flight path and commands, performing real-time calculations and controlling the aircraft to achieve flight control and navigation. It uses a MEMS inertial measurement unit to measure and collect the carrier's raw inertial navigation data, including rate gyro data and accelerometer data. A GNSS receiver obtains GNSS position and velocity data; dual GNSS is used to improve performance and reliability. An atmospheric pressure sensor receives total and static pressure from the airspeed tube to calculate parameters such as true airspeed, indicated airspeed, and flight altitude. Inertial navigation and GNSS combined navigation calculations are performed, and then the aircraft's control surfaces are controlled to achieve climbing, descending, and turning.

KCD-3 Servo

The KCD-3 servo motor consists of a maxon imported motor, a low-backlash harmonic reducer, and a precision non-linear wound angle sensor.
