The Trimble® DSM™ 232 modular GPS receiver is your ideal solution for dynamic marine positioning tasks such as dredging in ports and navigation channels where it is integrated as the positioning sensor component. The Trimble DSM 232 receiver is capable of sub-meter, decimeter and centimeter accuracy and provides a complete range of GPS (Global Positioning System) positioning techniques including:

• Beacon
• DGPS
• Omnistar
• SBAS
• RTK

The Trimble DSM 232 GPS receiver is also easy to upgrade to increase performance as your positioning requirements change.

The entry-level Trimble DSM 232 is a high-performance, sub-meter GPS receiver that includes a combined beacon, GPS and satellite differential correction antenna. It uses free public (MSK beacon or Satellite Based Augmentation System (SBAS) corrections such as WAAS) or subscription-based private differential correction services (OmniSTAR VBS) to calculate sub-meter positions in real time.

The Trimble DSM 232 GPS receiver is also available in two dual-frequency models to use the accurate satellite differential based OmniSTAR¹ XP/HP correction services delivering decimeter level accuracy, or to use the Real Time Kinematic (RTK) capabilities for centimeter accuracy in three dimensions.

In situations where your applications may change over time, Trimble can supply an upgradeable model of the Trimble DSM 232 sub-meter receiver so you can upgrade the receiver to greater accuracies at a later stage.

¹ Note - OmniSTAR VBS/XP/HP require a subscription from the service provider so check with them for availability and operating constraints in your area.

Key Features and Benefits

The Trimble DSM 232 GPS receiver offers the following key features and benefits:

• Modular GPS receiver with external GPS Antenna for flexible and secure setup configurations.
• Support for external radio modems of choice allows easy integration with your existing systems and licensed frequency bands.
• Multiple GPS techniques supported within a single upgradeable receiver - Beacon, DGPS, SBAS (e.g. WAAS, EGNOS, MSAS), Omnistar VBS, XP, HP service, RTK
• Multiple GPS accuracies supported in a single upgradeable receiver - Sub-meter, decimeter, centimeter to meet a wide range of positioning, measurement, navigation, and placement applications.
• Display and keypad for fast configuration without an external controller or computer. Minimizes integration development time to support real-time position output information from the receiver.
• Supports industry-standard RTCM, NMEA 2000® and CMR data stream formats and correction messages on multiple communications ports and integrates quickly with existing software applications.
• Supports Trimble TSIP protocol for compatibility with previous Trimble DSM GPS receivers.
• Rugged, modular GPS antenna design allows the unit to be moved quickly from vessel to vessel.
• Optional DGPS Reference Station capability (RTCM output) with Zephyr Geodetic antenna
• Full compatibility with the Trimble HYDROpro™ marine software application for a turnkey positioning solution.
