TOPGNSS new small volume RTK rover GPS module, differential FIXED receiver antenna RTCM3.X protocol, high precision agriculture

New product small size RTKGPS module GN-02B The GN-02B enhanced navigation and positioning G-Mouse product designed and produced by TOPGNSS is a single-frequency RTK enhanced chip and antenna integrated board product launched by TOPGNSS for the high-precision application market. It adopts GNSS chip, supports multi-system joint positioning, integrates unique RTK algorithm, and exerts the super performance of single-frequency RTK positioning.GN-02B supports BDS B1, GPSL1, Beisan, QZSS and other signals. At the same time, the on-board dual-feed point self-developed high-precision single-frequency positioning antenna is used to effectively suppress multipath signals. The antenna trace is the shortest, the anti-interference effect is good, and the positioning effect is improved; the GN-02B has low power consumption and consistent positioning accuracy ( It has significant advantages in performance such as sub-meter level, half the sky, shaded environment) and sub-meter level positioning acc
