1, vision processing unit: Currently need to buy from the United States INTEL under Movidius company, vision processing unit is also called VPU, his role is: embedded deep neural network, pose estimation, 3D depth sensing, visual inertial ranging, and gesture\/eye tracking. It's very important for drones.
2. Gyroscope: Currently it needs to be imported from Invensense and ADI in the United States. As the core of the drone core, gyroscope machining technology requires the integration of various products onto silicon-based microelectronic chips, thus enabling the electronization of many sensors. However, there is still a big gap between China's gyroscope industry and the world's advanced level, and the production of acceleration sensors, gyroscopes, and electronic compass necessary for drones has been in the hands of European and American countries, while China's UAV companies can only carry out programming and other work, and can not touch the core.
3, GNSS module: Currently only European U-blox module can be purchased. U-blox has developed very fast, the technology is quite mature, support GPS and Beidou dual mode, star search fast and high accuracy. Because DJI needs to export to the global market, and our domestic Beidou can not replace GPS, and the self-developed civil-grade Beidou chip still cannot achieve satisfactory results in performance, power consumption, especially can not meet the requirements of civil drones such as high-precision, high-altitude, high-speed, and multi-angle.
4. Main control chip: At present, only the ARM chip of ST company and the dedicated CPU provided by Qualcomm \/INTEL for drones are used.
5, camera: At present, domestic camera technology has been rapidly developed, but the mainstream drone is still supporting SONY's camera.
The chips used in DJI's drones are domestically produced.
Dji in its latest generation of consumer aerial drone - DJI Phantom 4, the first to use the core solution LC 1860, this chip was also applied to the first generation of zero intelligent control drones.
