Marine construction receivers

Trimble has introduced two new Global Positioning System (GPS) receivers designed specifically for marine construction applications. The Trimble SPS361 and Trimble SPS461 GPS dedicated marine heading receivers deliver both precise GPS heading together with Differential GPS (DGPS) or Real Time Kinematic (RTK) positioning. When used with Trimble HYDROpro marine software, the receivers are suitable for the precise placement of structures such as piles, bridges, caissons, marinas, and coastal defenses; dredge head positioning; vessel positioning and tracking; and offshore rig positioning with anchor handling.
