Trimble GNSS Hardware for Marine Construction
Trimble offers a reliable suite of GNSS hardware purpose-built for marine construction environments. From rugged receivers to high-performance antennas and radios, these solutions ensure precise positioning and seamless connectivity across a range of marine applications.
Trimble MPS566 Marine GNSS
The Trimble MPS566 is a highly versatile, rugged and reliable Global Navigation Satellite System (GNSS) marine positioning solution. ≈It features maximum connectivity with Bluetooth, Wi-Fi, UHF radio, cellular modem and two MSS satellite correction channels.
GNSS Antennas
Trimble offers several models of GNSS antennas to suit your specific application, signal tracking and budget requirements — including the SPS785 and R780.
Marine Inertial Positioning System
The Trimble Marine Inertial Positioning System is a compact dual-antenna solution that delivers robust and precise 3D position and orientation data in the most challenging marine environments.
GNSS Modular Receivers
Save time, money and headaches with the R750 connected base station solution, which includes remote monitoring, alerts, an internal radio, and rover capability. The BX992 GNSS Heading Receiver is a dual-antenna unit offering precise heading capability and multi-frequency support for all known constellations.
GNSS Correction Sources
Your GNSS operations are only as accurate as your correction source. SITECH Solutions can help you choose the right option for your site — from local GNSS base stations for maximum precision to virtual correction sources for smaller projects.
Trimble GNSS Radios
Trimble GNSS radios are engineered for rugged reliability and flexible configuration, helping you maintain efficient and accurate communication on the marine construction site.
