announces that its latest generation GNSS receivers for marine construction and hydrographic survey now support Fugro’s Marinestar positioning services.
The Fugro Marinestar positioning service expands the operating environment for contractors using the Trimble Marine Construction GNSS receivers and enables decimetre accuracy for precise placement of dredging equipment and dredged materials.
Contractors can now conduct dredging work up to 20 miles offshore using satellite-delivered Marinestar corrections with Trimble SPS855 and SPS555H GNSS receivers, without relying on land-based infrastructure such as reference stations and radio networks.
The Trimble SPS855 GNSS modular receivers provide accurate water level information and tidal height for construction or dredging locations at significantly lower cost than with conventional methods. Their modular design allows the contractor to place the receiver inside the vessel cabin for maximum security and protection from the environment while mounting the GNSS antenna outside for optimised signal strength.
The Trimble SPS555H heading add-on receiver provides exact heading information for projects that require precise orientation of a dredging vessel.
Fugro offers two options in its Marinestar positioning service: Marinestar GPS is a high-performance, high-accuracy GPS augmentation service while Marinestar GNSS is a high-performance augmentation service for both the GPS and GLONASS Navigation Satellite Systems.
The new Trimble SPS855 GNSS modular receiver and SPS555H heading add-on receiver are available now through the Trimble Marine Construction distribution network.
