RAC is a new positioning technology invented and developed by BroadGNSS Technologies. RAC stands for "real-time array calibration." RAC is an innovative technology to improve the positioning accuracy of GNSS. It coexists with RTK, PPP, RTX and other traditional technology. Through innovative antenna array design and software algorithms, the horizontal positioning error is greatly reduced, and the positioning accuracy and stability are greatly improved.
This technical scheme does not rely on reference stations, and achieves positioning accuracy in centimeters only by using GPS / Beidou common civil single-frequency signal. RAC can be used indifferently across the globe – no additional tech or money required. RAC’s appearance is a major milestone in the development history of the world's satellite navigation and positioning technology.
