For waterway and harbor applications, the Trimble DSM 232 GPS receiver allows operators to save time and reduce operational costs. Setup time is greatly reduced as well as cost of ownership because the operator can purchase an entry-level receiver and upgrade as company needs grow. With the DSM 232, one receiver can be used for positioning over large geographic (land based) areas with or without a base station and external radio modems, eliminating the need for multiple GPS receivers.
The receiver features an integrated keypad and screen, and outputs industry-standard NMEA messages for fast, easy integration into existing operations or new installations. The DSM 232 can be used with PC-based software such as Trimble's HYDROpro Software for waterway construction projects.
The Trimble DSM 232 GPS receiver provides system integrators and waterway operators with a flexible solution. Now they can choose one receiver for submeter level GPS requirements through to centimeter level GPS positioning. The Trimble DSM 232 installs easily and is able to withstand tough environmental conditions. Additionally, the modular GPS receiver and antenna design allow the unit to be moved quickly from vessel to vessel.
The Trimble DSM 232 GPS receiver allows users to choose the GPS correction method and accuracy required to suit their applications. This GPS technology gives operators high-performance capability, ranging from one centimeter with the Trimble RTK solution, to decimeter level with the OmniSTAR-XP/HP satellite service, or to submeter with Differential GPS (DGPS) options. OmniSTAR satellite-based services are available in specific geographic regions worldwide and require a subscription from the service provider; check with OmniSTAR for availability and operating constraints in your area. The entry-level model delivers submeter accuracy using the DGPS beacon and OmniSTAR VBS service or meter level when using Satellite Based Augmentation Systems (SBAS) such as WAAS or EGNOS.
