[Abstract]:Small unmanned helicopter is widely used in many military and civilian fields such as reconnaissance of military targets and search of personnel because of its advantages such as light weight, small volume, strong concealment, high flexibility, low cost and so on. But the acceleration, the uncertainty of the angle of flight and the external factors such as air resistance, weather factors and working environment all make the flight path of the small unmanned helicopter difficult to predict. Therefore, it is of great practical significance to understand the real time position of small unmanned helicopter in order to observe whether it is flying on a safe route. In this paper, the implementation scheme of real-time positioning system for small UAV is studied. This paper studies and designs the real time positioning system of small unmanned helicopter with independent intellectual property right. GPS global positioning system plays an important role in the real time positioning system of small unmanned aerial vehicle. Firstly, the structure and working principle of GPS system are studied in this paper. Coordinate transformation of space navigation system is studied. Taking embedded linux as operating system, using S3C2440 chip and communication module STM32 as hardware development platform, with corresponding application software, the implementation scheme of real-time monitoring the location of small UAV is studied. To explore and study the real-time positioning system of small unmanned helicopter with independent intellectual property. On the basis of discussing the technical knowledge of GPS and embedded system, this paper presents the overall design scheme of real-time positioning system for small unmanned helicopter based on Linux operating system. The microprocessor of this design is based on Samsung S3C2440 chip, Linux is used as embedded operating system, and new sirf3 generation chip REB3571) is used. The GPS module on a small unmanned helicopter receives space wireless information from a satellite. Then the GPS module transmits the received information to the S3C2440 chip and the S3C2440 chip processes the received positioning information to the ground monitoring station through the space wireless communication system. Finally, the article is reviewed and summarized, and the defects are pointed out, and new ideas for improvement are put forward.
