Android-based Design And Implementation Of Ground Station Software For Unmanned Aerial Vehicle

Unmanned Aerial Vehicle(UAV) flight systems includes unmanned aircraft system and ground control station system. Unmanned aircraft system is mounted on the aircraft, mainly responsible for recording online flight data, operating flight control algorithms and ensuring good communication and collaboration with the ground station. Ground control station is a command and control center of the UAV flight systems, mainly used for the operator who operates the UAV ground station to control and manage. Although the UAV ground station is gradually raised during the process of research, development and application of the modern UAV, its significance is great in flight system.The Android operating system-based ground control station is researched and developed in this article for the four-rotor flying system. MK official control board is selected as hardware platform of unmanned aircraft system, and O nda V819 mini Tablet PC is as hardware platform of ground station,which are all equipped with the appropriate software which is depended on their hardware platform. Ground station software communicates with unmanned aircraft system via the Transmission Control Protocol, and unpacks the received data packets, then decodes the data packets based on valid MK encryption and decryption technology to get various flight parameters and the sensor parameters.Android EditText component is used for the display of real-time debugging data on gro und station interface, and AChart Engine which is provided by Google is used to draw real-time two-dimensional graphics whose parameters are changing, and SQLite database is used to store and query the received data. It is good for the ground station operator to timely and accurately understand the ground station of UAV’s flight, in addition, the ground station can send the packaged control commands to the onboard system to calibrate the data 、start the motor、modify the throttle and turn off the motor and do other operations.The ground station which is tested by experimental could meet the basic requirements of the subject, has strong stability, and provides a reference for further expansion and development.
