Single and Multibeam Hydrographic Survey
Reliable and efficient survey planning, data acquisition, editing, data processing and volume calculations.

Marine construction presents its own unique challenges and requirements. No matter how complex your project, Trimble has marine construction hardware, software and positioning sensors to help you meet and exceed them.
With Trimble marine systems, dredge to an exact depth, dump dredged material in a defined location and confirm depth with a multibeam hydrographic survey.

The Trimble MPS865 is a highly versatile, dual antenna, rugged and reliable Global Navigation Satellite System (GNSS) marine positioning / heading solution.

The Trimble R750 GNSS Modular Receiver offers numerous features and benefits for contractors involved in marine construction, including:

The Trimble SPS356 GNSS Beacon receiver is the next generation L1 Beacon receiver that is capable of using RTCM DGNSS (multi-constellation) corrections when available. The SPS356 includes Wi-Fi, Ethernet and Bluetooth capabilities, expanding system integration and connectivity options.
The SPS356 is an ideal solution for a wide range of marine construction applications including:
The SPS356 includes Wi-Fi, Ethernet and Bluetooth capabilities, expanding system integration and connectivity options. Using Wi-Fi, the SPS356 can be accessed using any device with an Internet browser, including smartphones or tablets, for configuration and monitoring.

The Trimble Marine BX992 is a dual-antenna multi-frequency GNSS receiver with precise heading capability. The Marine BX992 comes standard with GPS, QZSS and GLONASS installed.The BX992 provides scalable precisions up to centimeter accuracy position in a compact package. By integrating the latest GNSS technology from Trimble, it provides robust high accuracy positions and orientation. It offers MSS L-Band support for Marinestar or Trimble RTX services so the BX992 delivers precise position without the use of a base station.
Dual Antenna Input
The dual antenna input provides precise heading compared to single antenna systems which have difficulty determining position relative to the object of interest, especially when dynamics are low.
Rugged, But Flexible Interface
The BX992 offers easy integration and dependability. The BX992 is built to perform reliably and rigorously in harsh environmental conditions.
Features
The TELEDYNE Z-BOAT 1800-T designed and manufactured by Teledyne Oceanscience is a high-resolution shallow water hydrographic unmanned survey vehicle with an Odom Echotrac E20 Singlebeam Echosounder and dual antenna Trimble BX992 GNSS heading receiver. Both sensors can be removed and mounted on other vehicles of opportunity to maximise data collection capabilities.
Collect survey data in previously inaccessible areas, from shallow to deep sea. The combination of Trimble’s precise heading and positioning/guidance paired with Teledyne’s accurate and precise sonars allow for best in class data collection under harsh conditions. Remotely view Z-Boat operations or processed data with Trimble Marine Construction software.
