Kongsberg DPS232 differential positioning reference system
DPS232 is a new generation GNSS differential positioning reference system produced by Kongsberg. Mainly targeting ship dynamic positioning DP systems, integrating GPS and GLONASS dual frequency satellite reception, compatible with future Galileo satellite systems, DPS232 is designed to provide reliable position reference data for offshore ship operations. DPS232 is widely installed on ships such as offshore support vessels, shuttle oil tankers, FPSO floating production storage and offloading vessels, and serves as an important external position sensor for dynamic positioning systems, meeting high-precision positioning requirements in complex sea conditions.
Product function
- Absolute position measurement: Receive multiple satellite signals, combine multiple differential correction sources, and output the ship’s high-precision absolute latitude and longitude position, providing a position reference for the dynamic positioning system.
- Provide a position reference source for DP power positioning, and the DP controller relies on the device’s position data to complete ship fixed-point maintenance and trajectory control operations.
- Support various differential signal inputs such as SBAS, commercial differential, IALA beacon, etc., switch under different sea conditions, and ensure positioning accuracy; Can dock with MRU motion reference unit to complete ship attitude compensation and offset positioning deviation caused by ship sway.
- Output NMEA and internal protocol positioning messages through Ethernet and serial port, which can be connected to ship automation and navigation monitoring systems. It also has system alarm output and reports status information to the central control in case of faults.
