The XP3.1 Standard INS/Avionics system will control the helicopter precisely and reliably at any flight altitude, in most weather conditions, If GPS signal is lost for more than 10 seconds, the helicopter automatically turns into attitude hold mode.
Main Characteristics
1. Autonomously hovering with high precision.
2. When autonomously hovering, the helicopter altitude and position can be locked. Flight velocity in one direction corresponds a given RC stick volume, so users may control only one channel at time.
3. Under the locked altitude, with the help of XP 3.1, operators can easily control the helicopter to do the turn-coordination.
4. Amend errors raised between hovering and flying automatically.
5. The main differences between DJI XP3.1 and the stability augmentations system based on CCD sensor: DJI XP3.1 can to any altitude within the remote control smoothly, without the height and surface texture restraints. No frequent switching between various modes, the speed can be accreted to 0.1m/s or less.
6. Automatically turn into hovering state when receiver signal is lost (enter the Fail Safe mode).
1.Improve the accuracy and real-time performance of the controller by using 2 separate DSPs (digital signal processor) to calculate altitude and control algorithm.
2. Provide superior position accuracy by using a high performance 16-channel GPS receiver.
3. Enclose high-reliability tri-axial gyroscopes and accelerometers of MEMS.
4. Building algorithm can facilitate users to do the hard and soft iron magnetic field compensation for eliminate the magnetic interference.
5. The system dedicates CPLD to decode and encode servo signal for higher reliability and compatibility for most RC receivers.

By combining the high precision of position measurements from the GPS receiver and environment independent and high update rate nature of inertial navigation sensors, the autopilot is able to provide accurate position and altitude hold (within 1-2m or better), and constant velocity cruise control at any height and light condition.
XP3.1 Standard Provide accurate position and altitude hold (within 1-2m or better), and constant velocity cruise control at any height and light condition.

In Automode, the altitude can be locked; the nose direction and the helicopters velocity command, back and forth, left and right, up and down, can be issued by RC separately and get accurate feedback control through on-board automatic control algorithm. Even people, who are flying the RC helicopter for their first time, can learn to control the helicopter in few minutes. There is a hovering zone in the middle of the RC stick. When the RC stick goes back to the middle and enters the hovering zone, the system will make the helicopter enter auto-hovering in a short time.
After entering autopilot mode, the flight speed is in proportion to the volume of RC stick.
When the RC stick is pushed to the limit, the corresponding maximum flight speeds are as followings:

The system remains the traditional manual mode. Under this mode, operator can control the helicopter as ordinary RC helicopter.
