Trimble SPS361 and SPS461 GPS Heading and Positioning Receivers for Marine Construction and Hydrographic Survey

The Trimble® SPS361 and SPS461 GPS Heading and Positioning Receivers are modular, dual-antenna systems for marine construction and hydrographic survey. They partner with Trimble HYDROpro software to provide the tools for precise placement of piles, bridges, caissons, offshore drilling rigs and coastal defenses.; providing the user with dredge head positioning; vessel positioning, vessel heading, and pitch or roll. The Trimble SPS361 supports MSK Beacon and OmniSTAR VBS corrections. The SPS461 includes all the features of the SPS361 plus its available with internal 450 or 900MHz radios and is upgradable to varying levels of positioning, including precision RTK. Both the SPS361 and SPS461 provide Precise GPS Heading.

The Trimble SPS361/461 GPS Heading Receivers offer:

• Rapid deployment, easy integration
• High-precision, dual-frequency GPS heading with fast initialization
• Data to easily determine the position of other sensors on a vessel (in partnership with HYDROpro)
• Support for a range of correction services to provide the position accuracy you need

As one-receiver systems the Trimble SPS361/461 are cost-effective, plus ideal for either permanent or temporary installation. Both receivers employ dual-frequency antennas for enhanced performance over single-frequency antenna solutions—Trimble offers a range of antennas to suit each marine customer's application needs.

The Trimble® SPS361/SPS461 is supported by HYDROpro marine construction software (download equipment handler file) or can be easily integrated into any OEM solution via standard NMEA data output.
