The KFS-3B flight control and navigation unit consists of a MEMS inertial measurement unit, a GNSS receiver, a barometric pressure sensor, and a main controller based on a high-performance ARM processor. Based on sensor measurements of status information, the flight control and navigation unit pre-sets flight paths and commands, performing real-time calculations and controlling the aircraft to achieve flight control and navigation functions.
The MEMS inertial measurement unit measures and collects the carrier's raw inertial navigation data, including rate gyro data and accelerometer data. The GNSS receiver obtains GNSS position and velocity data; dual GNSS is used to improve performance and reliability. The barometric pressure sensor receives total and static pressure from the airspeed tube, calculating parameters such as true airspeed, indicated airspeed, and flight altitude. Inertial navigation and GNSS combined navigation calculations are performed, and then the carrier's control surfaces are controlled to achieve carrier climbing, descending, and turning.
