S70N Flight controller, Hybrid UAV Flight Control and Navigation System



S70N flight controller for drone and navigation system is a multi-redundant high-precision integrated navigation system (with 0.1° dynamic attitude accuracy), which includes a high-precision differential positioning module (GPS), and a dual-antenna yaw direction finding module (heading accuracy is 0.1° with 2m baseline between the antennas). The system has high integration, high accuracy, and multiple redundancy. It is small in size and lightweight and supports deep user customization.

The S70N UAV Autopilot is suitable for various conventional fixed-wing, vertical take-off and landing fixed-wing, and multi-rotor UAVs that require fully autonomous take-off and landing functions.


  • Integrated high-precision multi-redundant IMU which dynamic attitude accuracy is 0.1°.
  • The reserve sensor can be switched at any time, which has the dual advantages of high measurement accuracy and high reliability.
  • Integrated high-precision BD/GPS real-time differential positioning module. The satellite navigation update rate is up to 20Hz, and supports dynamic differential positioning (RTK modules)
  • Integrated high-precision dual-antenna directional system with heading accuracy of 0.1° (when the baseline distance between the two antennas is 2m), which together with the dual-redundant magnetic compass system forms a three-redundant heading system.
  • High navigation system reliability.
  • 12 PWM control outputs, 4 serial port outputs, 2 ADC inputs, 2 speed monitoring, 1 CAN, 1 SBUS input, and 1 SBUS output.
  • Supports direct raw data output of satellite navigation and integrated navigation.
  • Supports flight control-in-the-loop formation simulation (flight control embedded digital aircraft model).
  • Supports taxiing take-off and landing for fixed-wing, vertical take-off and landing for fixed-wing, multi-rotor, and other aircraft types.

The complete emergency protection mechanism can protect against low voltage, low oil volume, low rotation speed, abnormal attitude, abnormal altitude, low GPS positioning accuracy, navigation system failure, and more. Failsafe triggering when the UAV goes beyond the safety fence, beyond the control radius, or in case of the remote control failure is supported as well.

The user can define 100 emergency landing points, and in case of an emergency, it will automatically land at the nearest location. Also, 10 flight routes, including 8 mission routes can be defined, where a single mission route can have up to 800 waypoints. It is possible to automatically generate a circling route, circling center, and circling radius.

Flight information and mission information are recorded and downloaded separately. The flight information recording time is up to 9 hours. The ground control software supports online maps and automatic surveying and mapping route planning for irregular multi-measurement areas. It also supports the automatic planning of patrol routes such as oil and electric power lines. However, users are cautioned to conduct a complete pre-flight inspection to ensure no faults in the designed plan occurs.
