The full name of the UAV is an unmanned aircraft, is the use of radio control equipment and self owned program control device to manipulate the unmanned aircraft. No driver on the machine, but the installation of automatic driver, program control device and other equipment. Ground and naval vessels or tools remote station personnel by radar and other equipment, the for tracking and positioning, remote control, telemetry, and digital transmission. Including the unmanned helicopter and fixed wing aircraft, multi rotor aircraft, unmanned airship, unmanned wing machine etc.. According to the division of different areas, the UAV can be divided into military and civilian consumption level and three categories.

UAV has appeared in agriculture, mapping and exploration of multiple oil pipeline, disaster relief and other fields, its hidden behind the commercial value is being constantly mining, whether it will like smart phones that mode of industry and business interests to bring revolutionary influence?
Machine industry chain can be divided into the segments of R & D, production, sales, service and, concrete can be divided into product research and development, the development of flight control system and engine key parts and components production, any load manufacturing, UAV machine assembly, unmanned aerial vehicle sales, UAV control training, business operation services, integration application service link.
UAV industry chain participants mainly include two categories:
One is like the big Jiang, GoPro, such as machine manufacturers;
The other is for unmanned aerial vehicle (UAV) to provide hardware and software of the upstream manufacturers, including chip, flight control, batteries, sensors, GPS, gyroscope, dynamic system, data system, figure transmission system, electronic components, computer training and so on.
In terms of hardware, the chip is the core component, which directly determines the performance of the UAV control, communication capabilities and the ability to deal with image information. UAV with other familiar consumer electronic products, chips, manufacturers in the middle, peripheral industries, is not we imagine so mysterious and distant.
UAV main control chip manufacturers have: micro rk3288 Qualcomm (qcom), Intel (Intel), St (STMicroelectronics), Ti (Texas Instruments), Samsung (Samsung), ATMEL, ATMEL, new Tang (Nuvoton), XMOS, NVIDIA, rockchip. The other and so on.
Manufacturers of its enthusiasm is not so high, but as it is in agriculture, logistics and other applications under the scenario of the demand is constantly being excavated, once enough to sweep the industry's downstream enthusiasm also naturally followed. Editor's inventory of the current mainstream of the 8 main UAV control chip, for your reference:

1 STMicroelectronics STM32 series. STM32 STM32 F0/F1/F2/F3/F4/F7/L0/L1/L4 series is a series of products, including STM32, F4 series are widely used in uav. Based on arm cortex-m4 stm32f4 Series MCU using STMicroelectronics NVM technology and art accelerator, this is so far all Cortex-M core micro controller based on achieved the highest benchmark test scores in up to 180 MHz operating frequency through the implementation of flash the processing performance reached 225 DMIPS/608 coremark.
2 Qualcomm snapdragon Flight platform. Xiaolong Flight is a highly optimized 58x40mm development board, specifically for the consumer level UAVs and robot application and design.
Snapdragon flight contains a single snapdragon 801 SOC (by four clocked at 2.26GHz core) and supports GPS, 4K video capture, strong connectivity and advanced unmanned aerial vehicle (UAV) software and development tools, dual channel Wi Fi and Bluetooth module to support real-time flight control system, has a global navigation satellite system receiver, support for 4K video processing, support for fast charging technology, and all this were integrated in a piece the size of a business card on the motherboard. Mobile brings the most cutting-edge technology to create new consumer level uavs. These functional components form an asynchronous computing platform to support the development of advanced features such as collision avoidance and video stability.
3 Intel atom processor. In the field of unmanned aerial vehicle using Typhoon H Yuneec technology, the equipment has the function of collision avoidance, with convenient take-off, equipped with 4K camera and 360 degrees universal joint, as well as remote control built-in display and other features.
The custom PCI-express quad core Intel Atom processor card, to deal with the real-time information of the distance and the sensor, and how to avoid close obstacles. From the hardware part, it is to support the Intel real sense of the 3D camera; from the software part, it is Intel "real sense" calculation of SDK;
4 Samsung Artik chip. Samsung artik chip has three types, which applied to the UAV is mainly artik 5, artik 5Artik 5 sizes for 29x25mm, equipped with 1GHz arm dual core processor (Mali 400 MP2 GPU), collocation is 512MB lpddr3 ram and a 4GB eMMc flash. Support Wi-Fi, low-power Bluetooth, support 802.11 b/g/n. In addition, the chip will also be able to decode the H.264 format of 720p 30fps video decoding, and provides TrustZone.
5 TI OMAP3630. Texas Instruments OMAP once in single core era of smartphones scenery infinite, but with multi-core become mainstream, and Texas Instruments, gradually fading out of the consumer electronics, omap3630 battlefield is also transferred to the unmanned vehicles in emerging markets.
6 Atmel Mega2560 chip. Many are using the AVR Atmel processor chip in the UAV, but in the country by STMicroelectronics occupies most of the market.　　
7 XCORE XMOS multi core micro controller. Multi axis aircraft need four to six a brushless motor (motor), used to drive the rotor uav. And the motor drive controller is used to control the speed and direction of the uav. In principle, a motor needs to configure a 8 bit MCU to do control, but there is also a MCU control of multiple BLDC motor program.
8 New Tang MINI 51 series. Mini51 Cortex-M0 32-bit microcontroller series and its characteristics as wide working voltage range of 2.5V to 5.5V and - 40 DEG C ~ 105 DEG C temperature, 22.1184 MHz high precision RC oscillator (+ 1% accuracy at 25 DEG C 5V), and build data flash and undervoltage detection and rich peripherals, the integration of multiple serial transmission interface, high anti interference ability (8Kv ESD/4KV EFT), online system update (ISP), online circuit update (ICP) and online application update (IAP) to provide encapsulation tssop20, QFN33 (4mm * 4mm and 5mm x 5mm) and the lqfp48.
