The Application of RTK for GPS+BDS System in Geographical Information Collection System on Remote-controlledvehicles

摘要: GPS-RTK作为全球定位系统(GPS)测量技术提高定位精度的一种方法得到了大力推广和广泛应用。现今,北斗卫星导航系统(BDS)已建成区域导航星座,并具备了导航定位服务能力,且已正式提供连续无源定位、导航、授时等服务。但由于BDS单星座定位存在一些不足,导致了定位精度偏低,因此多频多系统融合定位导航研究成为了一个技术新热点。文中通过介绍RTK技术,引入了GPS+BDS双系统下RTK的应用思路,并指出RTK技术在地理信息采集系统中的优势以及实际应用中应注意的问题,为类似工程应用提供一定的参考价值。Abstract: GPS-RTK as a method of improving positioning accuracy in Global Positioning System (GPS) measurement technology has been widely promoted and used. Nowadays, BeiDou satellite navigation system (BDS) has been built regional-navigation constellation.BDS has been officially provided for continuous passive positioning, navigation, timing and other services. However, due to the shortcomings of BDS single constellation positioning, resulting in low positioning accuracy. So multi-frequency multi-system integration navigation and positioning has become a new hot spot for navigation and positioning research. This paper introduces RTK technology and the application of double-difference RTK in GPS+BDS system. It also points out the advantages of double-difference RTK in geographical information collection system and the problems in practical application. It provides some useful reference value for similar engineering applications.
