Trimble Marine GPS

Trimble offers a range of high-precision centimeter level (RTK) positioning as well as sub-meter (DGPS) positioning solutions which can be integrated with other marine sensors, the HYDROpro? Construction and the Terramodel? HDMS to create application specific marine systems.

• DGPS - Provides sub-meter horizontal position accuracies. DGPS requires a source of satellite corrections such as IALA Beacon, EGNOS, WAAS, proprietary SBAS or DGPS base station transmissions. A Trimble DGPS receiver can be combined with a dredge head depth sensor and radio tide gauge for dredging systems.
