Introduction
LEO GNC (Micro Guidance Navigation Control System) is a new generation of
navigation flight control system designed for industrial-grade drones. It features
with high integration, high reliability and high cost performance. It supports VTOL
quad plane, fixed wing, helicopter, multi-rotor and other types of aircraft. .
LEO integrates IMU and a datalink with max 60km communication distance into
the control system. It equips with -15℃～85℃ temperature compensation MES
sensor and J30 aviation connector. LEO adopts a decoupled extended Kalman
filter, improved L1 guidance rate, and ADRC controller as core algorithm, which
has extremely high precision.
Features and applications
MEMS inertial measurement unit, triaxial magnetometer, barometric altimeter,
airspeed meter, GNSS module, triaxial magnetometer, barometric altimeter,
air speedometer, GNSS module. -15~85℃ temperature compensation for
MEMS IMU and triaxial magnetometer.
Built-in 900MHz data link, communication distance up to 60km*.
Dual integrated navigation system. Decoupled 17-order extended Kalman
filter to complete the information fusion. Automatically switch between the
GNSS/INS and AHRS/DR navigation modes according to satellite signals
Built-in shock absorption structure to reduce the impact caused by vibration
to IMU
Iproved L1 guidance rate and ADRC controller to improve control accuracy
and robustness.
With built-in global geomagnetic model, and compass calibration has been
tested in polar area. LEO can complete one-key compass calibration, take off
immediately after satellite positioning.

Powerful remote assistance service. Whenever and wherever you need
technical support, you can request AheadX's official remote technical support
via the Internet.
10 routes (The 10th route is the landing route for fixed wing or VOTL), max
200 waypoint of each route. It supports automatic route switch
With fixed-point, equal time, equal distance shooting function. Records the
POS data of the shooting point.
Any installation method. LEO equips with installing angle correction and lever
arm compensation. It can be mounted at any angle and position
Simulation training function. LEO can work with AheadX's semi-physical
simulator for pilot’s daily simulation training.
Bilt-in black box data logging function, it is able to cyclically record
approximately 60 minutes flight data . Supports external data recorders,
recording up to 2000 hours flight data.
Online upgrade. User can quickly get the latest firmware and ground station
software on the Internet.
User can turn off the internal data link and use external data link.

Flight controller installation and
connection
Thanks for purchasing our Leo GNC. This chapter will guide you how to install
and tune the flight controller. You can make the cables& wires and check it
according to the instruction. Please read this chapter carefully and make the
installation strictly abide to the guidance.
Self-prepared equipment
User needs to prepare the following equipment to work with: **Drone: ** **
Quad plane** - Hybrid fixed wing with four rotor configuration ** Fixed
wings**- Various fixed wings ** Multi-rotor** - multi-rotor drone. ** Data
link:** with RS232 interface. **Auxiliary control joystick:** AheadX A4RC01
auxiliary joystick is recommended; Support SBUS output; Radio controller with
more than 10 channels (eg FUTABA T8FG/T14SG). Computer:Recommend Intel
Core i3 processors, 2GB memory, 200M hard disk space or better configuration to
install our ground station software.
Cables&wires
Interface definition
There are two versions LEO flight controller, one is standard version and the other
is HV version. Standard version comes with J30J-21 rectangular connector and
HV version with J30J-37TJL connector. User can make cables according to the
interface or buy AheadX’s finished cables. Following chapters introduce the
installation of HV version LEO flight controller.
