摘要
GPS技术应用于测量是外业勘测的一项重大技术革命,其应用及开发的前景十分广阔,实时动态(RTK)定位技术在测量领域中蕴含着巨大的技术潜力,回声测深仪是一种水深测量仪器,只要测出超声波从发射至接收的时间间隔再根据超声波在水中的传播速度,即可计算出水的深度。文中主要介绍了GPS+RTK技术结合回声测深仪在煤矿沉陷区中的应用。
Surveying with GPS technology is a major technological revolution the outside survey,which has a broad prospect in further application and development.Real-time Kinematic(RTK)positioning technology in the field of measurement contains a huge technological potential.Echo sounder depth finder is a water depth measuring instruments.That is,the water depth will be calculated as long as having the time interval from being launched to being received and the speed of the ultrasonic velocity in water.This paper mainly introduces the application of GPS-RTK technology combined Echo sounder depth finder in Coal Mine Subsidence Area.
