The SinoGNSS A300 is a compact, all-in-one GNSS receiver that combines antenna, GNSS module and communication electronics inside a single sealed dome, built specifically for continuous structural and geohazard monitoring rather than everyday survey work. Running on ComNav's K8 GNSS platform, it tracks GPS, GLONASS, BeiDou, Galileo and other constellations across its receiver channels to deliver millimetre-level positioning for long-term deformation tracking. It is IP68 sealed with anti-vibration and anti-lightning protection, offers onboard memory for loop data recording, and connects via 4G, Bluetooth or UHF, with an MTBF rated above 50,000 hours for unattended 24/7 operation on bridges, dams, slopes and high-rise structures.
