Product Overview

The DPS232 is a professional marine-grade DGNSS differential positioning computing unit developed exclusively for Kongsberg full-series ship DP (Dynamic Positioning) control systems, widely installed on offshore platform supply vessels, FPSO, drilling rigs, dredgers, shuttle tankers and construction barges.

Its core function is to receive multi-satellite constellation signals from the roof GNSS antenna, resolve high-precision absolute geographic coordinates, heading and velocity data, and transmit standardized positioning messages to the DP main controller as one of the primary position reference inputs. In offshore tandem operation (such as FPSO and shuttle tanker oil transfer), it can work with DARPS232 to output centimeter-level relative distance and bearing between two vessels, drastically lowering collision risk during mooring and loading.
