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.
KFS-4 integrated control and navigation unit
The KFS-4 integrated control and navigation unit uses a high-speed, high-performance ARM as its main control chip, and incorporates a MEMS inertial measurement unit, GNSS receiver, atmospheric pressure sensors, etc., to construct a digital control system. Based on data from sensor measurements, it performs integrated navigation calculations, flight path prediction, and command control, calculating and controlling the servo output in real time to achieve flight control and navigation functions. In addition, the KFS-4 integrated control and navigation unit is designed with abundant communication interface resources such as RS422, CAN, and USB, facilitating future expansion and upgrades.
