The SinoGNSS A100 Pro is a compact, palm-sized smart antenna that combines a full-constellation, multi-frequency GNSS module, an integrated gyroscope, and a built-in datalink radio in one IP67-rated housing weighing about 750g. Designed for vehicle-mounted positioning, it outputs RTK/RTD fixes at up to 20Hz and includes DP-filter smoothing plus 4G and Bluetooth connectivity for flexible field or machine-control deployment. It is the antenna at the heart of ComNav's AG501 Pro autosteer system, and is the higher-spec sibling of the A100 Lite, which omits the gyroscope and datalink.
