摘要
随着全球卫星导航系统(Global Navigation Satellite System,GNSS)技术的迅速发展,定位精度持续优化,其应用范围越来越广。为了突破单基站载波相位差分(Real Time Kinematic,RTK)技术带来的局限性,网络RTK技术应运而生。网络RTK技术使设备在基准站网络覆盖范围内实现精准定位,因此在各个传统行业中的应用越来越广泛。广播电视的信号发射环节非常重要,由于广电发射塔一般地处高山地区,维护维修不便。基于此,设计一种基于网络RTK定位技术的高精度发射塔状态监测方法,可以在保证广电信号安全优质播出方面发挥重要作用。
With the rapid development of Global Navigation Satellite System(GNSS)technology,positioning accuracy is continuously optimized,and its application scope is more and more wide.In order to break through the limitations brought by single base station Real Time Kinematic(RTK)technology,network RTK technology came into being,which not only enables the equipment to achieve accurate positioning within the network coverage of the reference station,but also makes the technology more and more widely used in various traditional industries.At the same time,radio and television final signal transmission link is particularly important,because the radio and television transmission tower is generally located in high mountain areas,maintenance is inconvenient.Therefore,the design of a high-precision transmission tower condition monitoring method based on network RTK positioning technology plays an important role in ensuring the safety and high-quality broadcast of radio and television signals.
