GNSS Antennas for Construction
Trimble GNSS Antennas are built to deliver superior satellite signal reception in challenging construction environments. Whether mounted on a rover pole, base station, or machine, these antennas provide high-accuracy positioning to support surveying, layout, machine control, and as-built data capture. With support for GPS, GLONASS, Galileo, BeiDou, and other constellations, Trimble antennas help you work confidently with fast signal lock, low multipath interference, and long-term compatibility.
High-Performance GNSS Antennas for Every Construction Workflow
Trimble GNSS antennas are engineered for high-accuracy positioning in construction, surveying, and civil engineering environments. Designed to deliver reliable signal tracking in both open and obstructed conditions, these antennas support multiple GNSS constellations including GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS. Whether mounted on a rover pole, base station, or machine, they provide the foundation for precise data collection, layout, and grade control.
The Trimble Zephyr™ 3 Rover and Zephyr™ 3 Base antennas are built for field professionals who demand exceptional performance in dynamic environments. The Zephyr 3 Rover offers robust multipath rejection and fast satellite acquisition, ideal for stakeout and mobile surveying. The Zephyr 3 Base provides enhanced phase center stability for fixed base station setups, delivering centimeter-level accuracy and reliable RTK correction over long distances.
For rugged jobsite conditions, the Zephyr™ 3 Rugged is the top choice. Built to withstand moisture, vibration, and impact, it meets IP67 environmental standards while delivering the same high-precision signal tracking as the standard Zephyr lineup. Trimble also offers compact options like the GA830 and GA810, antennas tailored for vehicle-mounted setups and general construction tasks where size, weight, and cost efficiency are key.
All Trimble GNSS antennas integrate seamlessly with Trimble receivers, field controllers, and positioning software such as Siteworks and FieldLink. Backed by SITECH SA’s technical expertise and support, these antennas ensure dependable GNSS performance and long-term value across a wide range of construction workflows.
