Ace One is DJI’s latest achievement in GPS based helicopter autopilot systems. It combines the highest level of positional data from GPS Satellites, a 6-DoF inertial measurement unit, magnetic field meter, and a barometric altimeter with the most robust algorithms in automation control theory. From aerial filming, surveillance, to wide area surveying, Ace One’s exceptional performance excels in the most demanding industries and environments.
Ace One’s advanced algorithms allow it to work with a wide variety of VTOL platforms; from Bi-blade to Multi-bladed helicopters, with or without flybar, 3 or 4 servo CCPM, and electric or gasoline power plants.
A great trade in program for all XP3.1 owners, by sending in your XP3.1 together with a charge of USD 1,300 you will receive the latest Ace One.
Ace Waypoint is based on DJI 4th generation autopilot system in total autonomous flight with Ground Control System (GCS) which easily sets, edits and confirms flight waypoints for the mission utilizing 3D map in real time in flight feedback.
With the world leading UAV control system, DJI autopilot system offers stable, accurate and safe flight experience for customers. Complying with DJI 2-axis / 3-axis precision controlling and high speed attitude stable gimbal , Our system brings the best AP filming performance.
Designed for All UAV Platform:
ACE ONE works on all kinds of helicopters: Bi-blade, tri-blade aircraft, aircraft with or without flybar, all kinds of swash plates and rotor heads, electronic or gasoline or turbine helicopter engines. All types of helicopter can be installed with ACE ONE quickly and easily.
Compact Size & Lightweight:
ACE ONE components weight under 150g all together, which can be almost ignored from the payload. The size of the main controller is 61mm x 39.6mm x15.8mm, IMU module is 40mm x 31mm x 26mm, and the GPS module has a diameter of 50mm and a height of 9mm. The whole ACE ONE package is smaller than a standard package cigarettes box. ACE ONE even also can be installed on 450 size of helicopter.
The innovative build-in damping system allow the helicopter be installed without additional frames and dampers. The system helps customer to minimize size, reduce weight and simplify installation that can be applied on different helicopter models. Customers also have more options for physical installation.
Multiple Control Mode / Intelligent Switching:
ACE ONE offers four types of control modes : GPS Cruise Mode? GPS Atti. Mode, Atti. Mode, Manual Mode. Customer can switching among the four mode to adjust different flight environment even in the specially weak GPS environment as: Building clearance, valley clearance, bridge bottom or mountain cave. ACE ONE also can adjust automatically in the flight environment. For example when aircraft come through the bridge bottom with GPS intermittence, ACE ONE system switch between GPS mode and Atti. Mode automatically to make sure the safety and security of flight.
GPS Cruise Mode:
In GPS cruise mode, it is not only can keep aircraft attitude stable and also lock the aircraft position accurately. Flight speed control; Stick center position for 0m/s, its endpoint for maximum speed set by user. GPS cruise mode helps aircraft to have accurate and smooth flight movement that specially for aerial photography.
GPS ATTI. Mode:
GPS Atti. mode has the same performance with GPS cruise mode. The only difference is helicopter attitude control. Stick center position for 0? attitude, its endpoint for 45?which is a fixed limit. GPS Atti. mode can be used in promptly and big flight movement. It will bring to you a new and excellent flight experience.
Atti. Mode is suitable for no GPS signal or weak GPS signal environment. ACE ONE can control attitude stabilization and lock flight altitude accurate; Stick center position for 0? attitude, its endpoint for 45?which is a fixed limit. Atti. mode also can be used in promptly and big flight movement.
Manual Mode is mechanical driving directly. Flybarless supporting, autopilot will not keep the stabilization of aircraft. Manual Mode is suitable for experienced pilot.
Accurate Position & Altitude-Lock Hovering:
Autopilot system offers longitude & latitude locking and highly accurate hovering. Even in the windy environment, aircraft can hovering in small scale area. Accuracy: horizontal?2 meters. Altitude?0.5 meters.
High Accuracy / Driving Handfeel:
With the help of ACE ONE, controlling aircraft feeling like driving a car as simple and intuitive strong control of the flight itself has become an easy and precise operation; The pilot can focus more attention in other work, such as controlling the camera angle, without tension in the driving.
Semi Auto Take-Off and Landing:
In [GPS Cruise Mode] or [GPS Atti. Mode] or [Atti. Mode], requiring only pushing the throttle (collective pitch) stick gently to take-off helicopter, autopilot system will be in charge of the cyclic pitch/roll stabilization
Enhanced failsafe is the feature to ensure that the helicopter will hover automatically when it loss the RC signal. After lossing the signal in a certain time period, ACE ONE will calculate the safest way to home position and control the helicopter to return home. The helicopter will hover over your GPS start point eventually. This feature will protect your expensive payloads and equipments very well.
Built-In Gimbal Stabilization Function:
The gimbal stabilization module is compatible with almost all 2-axis gimbal systems. The system will adjust the gimbal and camera according to the attitude of the helicopter after setting the parameters the first time.
Built-In Tail Gyro / Flybarless Support:
The tail gyro and FBL have become standard features of ACE ONE. No more extra work installing additional tail gyros and FBL electronic parts. The helicopter’s electronic system has been greatly simplified. Therefore different electrical parts can be connected much more easily. One central piece calculates all of the flying configurations.
Built-In Engine Governor:
The engine speed lock and governor are also standard features for ACE ONE. The built-in engine governor simplifies the parameter settings, and increases the compatibility of the system. All you need is to connect an extra standard sensor to use.
Data Import & Export:
All the setting data can be saved as files that export from ACE ONE system . Or importing the file to current main controller to avoid reboot calibration.
Core Firmware Online Upgrade:
The professional DJI R&D team continuously provides the latest control algorithm and features/modules. You don’t have to mail the unit back or find service centre to upgrade anymore. All the upgrades can be done online. All you have to do is clicks.
Ace One can be upgraded to ground station that is more powerful un-man platform to satisfy the highly requirement of customer. Customer can active the different function to meet the real requirement.
Ground Station equipped with 3D map and virtually flight dashboard that offer the flight real time data of attitude, position, speed and angle. The radio signal, accelerator position and Servo voltage are also displayed on ground station.
Our autopilot systems and autonomous aerial platforms are used and applied in a wide range of commercial and industrial applications such as; aerial photography, surveillance, cartography, survey & rescue, power/ lines inspection, forest patrol, filming & advertising, police pursuit, military stealth, etc.
