Product Features
Compact and lightweight industrial rugged design
Sanding T20 has a compact body and weighs only 0.8kg. The internal structure is optimized. The GPS / GNSS four-quad point receiving antenna, strict electronic shielding, and special structure are all domestic advanced technologies, which effectively prevent photoelectric crosstalk. Multi-path effect, stronger star search ability. The data link, Bluetooth, and dual-band antennas are integrated into a compact all-in-one wireless receiver unit, which is specially designed for industrial IP67-class three-proof defense in harsh outdoor conditions.
UHF radio, GPRS / CDMA technology
Sanding T20 has a stable built-in UHF receiving station, and it also has GPRS network CDMA network modules coexisting at the same time. It is easy to operate and switch freely. A small card will take you to enjoy a stable, efficient and accurate network measurement world. Travel the web and measure easily.
Seamlessly compatible with CORS support GLONASS
Regardless of whether you choose to connect the Sanding continuous operation reference station CORS system or other brands of CORS systems, Sanding T20 can achieve seamless access and mature applications. At the same time, in the harsh receiving environment, it can combine GLONASS observation data with GPS data to provide more satellite information for positioning calculation and improve positioning reliability.
Powerful RTK operating software
Sanding T20 is equipped with imported industrial-grade handbook, bluetooth data transmission technology of German origin.
Benefiting from the great advantages of Sanding Software in the industry, Sanding RTK software system continues to refine the software functions while maintaining strong functions, humanization and diversity, and tailors professional mapping software for measurement applications in different industries.
