Trimble introduces marine construction receivers with GPS heading and positioning

The receivers are ideal for a range of applications when used with Trimble HYDROpro™ marine software, including: 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.

The announcement was made at the 2009 Trimble Dimensions User Conference.

The Trimble SPS361 is an entry-level DGPS Heading receiver with an internal MSK Beacon receiver and OmniSTAR VBS support. The Trimble SPS461 is a GPS Heading and Attitude receiver upgradable to the full range of positioning accuracies needed for marine construction applications, including Location Real Time Kinematic (RTK), Location RTK with precise vertical measurement, and Precise RTK positioning. The SPS461 supports MSK Beacon, external RTCM, OmniSTAR VBS, XP, HP, and precision RTK correction data delivered by an internal/external radio or Internet-enabled cellular modem.

The dual-frequency antennas of the Trimble SPS361 and SPS461 GPS Heading Receivers offer flexible antenna separation, enabling users to maximize precision for each installation, as well as expedite initialization and re-acquisition. The receivers can also be used for single-antenna applications if heading is not required. Trimble offers a range of antennas to suit both standard vessel installations and systems required for use in harsher environments such as dredging and piling.

The dual antennas of the Trimble SPS361 and SPS461 system provide the position, heading, and pitch or roll of a vessel. Customers can easily integrate the SPS361 and SPS461 receivers into existing systems.
