　　Beidou Application

　　RTK receiver has entered the era of multi satellite application based on BeiDou, becoming the first multi system and multi frequency RTK receiver with independent intellectual property rights in the world, the first in China. The multi satellite measurement receiver based on BeiDou adopts unique kRTK core technology and highly reliable carrier tracking algorithm to adapt to various environmental transformations and provide users with high-quality positioning results.

　　The dual star system (GPS+GLONASS dual system navigation and positioning) is a hot topic in the development of GPS RTK. It can receive around 14-20 satellites, which is incomparable to conventional RTK. This technology enables GPS equipment to achieve centimeter level accuracy in the shortest time and the strongest anti-interference and occlusion ability.

　　Single frequency dual star system (GPS+GLONASS, or GPS+BDS), RTK or PPP can achieve a positioning accuracy of 1CM.

　　VRS

　　VRS (Virtual Reference Station Virtual Reference Station) is improving the quality and distance of RTK positioning, enhancing the reliability of RTK, and reducing the time for OTF initialization. VRS technology can achieve an accuracy of 1-2cm in RTK positioning plane position at around 50Km, without the need to establish one's own reference station. Its application fields will gradually cover land surveying, Cadastral surveying, aerial photogrammetry, GIS, equipment control, electronic and gas pipelines, Deformation monitoring, Precision agriculture, water surveying, environmental applications and many other fields.

　　GPS

　　The satellite navigation application industry represented by GPS has become one of the eight internationally recognized wireless industries and one of the three fastest growing information industries in the world (cellular mobile/PCS, Internet/Intranet/Extranet, and global positioning system GPS). The integration and integration of GPS with computer, communication, GIS, RS and other technologies will surely expand the application field of GPS technology to a greater extent
