The Trimble MS975 GPS/GNSS Smart Antenna Base Station delivers high-precision positioning and enhanced RTK performance for construction, excavation and grading applications.
The Trimble MS975 produces the very best tracking to provide centimetre level accuracy on aerial, land and marine applications. Designed for fast-satellite re-initialization, it ensures reliable operation even near obstructions.
Supporting GPS, L2C, GLONASS, Galileo, BeiDou, and SBAS systems (WAAS, EGNOS, MSAS, QZSS), it provides superior satellite tracking with 200 channels across 44 satellites. Its rugged, full sealed chassis, single-cable connector, and quick-release mounting bracket ensure durability and easy installation in demanding environments. With real-time operational LED indicators and TCP/IP capability, the MS975 is an industry-leading GPS receiver for precision machine control, optimising productivity on every job site.
