SGB520

BeiDou probe mainly relies on cell phones to realize high-precision positioning. Nowadays, smart phones integrate all the sensors needed for mobile measurement: various cameras and video cameras, gyroscopes, compasses, depth cameras, odometers (pedometers), and everything in between. Especially its storage function, computing function (CPU + GPU), communication function, in all electronic products, cell phones are the most cost-effective. Moreover, the domestic network is now basically full coverage, cloud servers, cloud storage is powerful, and a thousand functional software can realize the needs of various industries. However, the form of the cell phone determines that it can not obtain high-quality satellite data, BeiDou probe came into being, SGB510, SGB520 with built-in high-precision spiral antenna, dual-frequency RTK technology, Bluetooth communication, cell phone network with differential service to achieve real-time differential data, access to high-precision positioning data. Compared with traditional RTK, no handbook is needed, and the lightweight design makes the body compact, easy to carry and simple to operate, which makes up for the defects of cell phones that can‘t obtain high-precision data.
