【Abstract】 According to the technology of GPS (global positioning system) and the electronic compass, a vehicle antenna automatic orientation system which is used in wireless LAN is designed in this paper. The system, which takes single chip microcontroller as the core, completes the real-time direction, latitude and longitude data gathering and processing work. Based on the arithmetic of the antenna orientation, the azimuth angle is given. The system could make the servo system complete the orientation. This design achieves the automatic directional function of the wireless LAN aerial mobile terminal antenna in the oil field.更多还原
