FUGRO 9200 IPDU GNSS CONTROLLER SATELLITE NAVIGATION UNIT

FUGRO 9200 IPDU is a high-precision marine GNSS controller interface unit for Fugro SeaSTAR 9200 series offshore satellite navigation and dynamic positioning systems. This marine GNSS controller interface unit receives raw GNSS satellite signals, processes L-band differential correction data from Fugro OmniSTAR/Starfix service, and outputs high accuracy position, heading and velocity data. This marine GNSS controller interface unit supports multi‑constellation tracking including GPS, GLONASS, BeiDou and Galileo, delivering decimetre‑level positioning accuracy for offshore DP vessels, survey ships and floating platforms. This marine GNSS controller interface unit transmits positioning setpoint to vessel DP control system, autopilot and loading computer via serial and Ethernet communication ports.

This unit is a vital marine DP navigation spare part for offshore vessel and survey vessel instrument cabinet overhaul. The marine DP navigation spare part works with GNSS antenna and Fugro differential correction service to continuously calculate vessel geographic position. The marine DP navigation spare part monitors signal quality and triggers fault alarms when satellite signal or correction data is lost. The marine DP navigation spare part can replace faulty original IPDU assembly to restore high-precision satellite positioning for dynamic positioning operation.

It delivers reliable differential GNSS positioning signal processing for offshore dynamic positioning systems. The differential GNSS positioning signal processing applies L-band differential correction to eliminate satellite positioning error. The differential GNSS positioning signal processing filters electromagnetic interference to maintain stable positioning performance under harsh marine environment. The differential GNSS positioning signal processing provides continuous position reference for vessel station keeping and offshore surveying.

FUGRO 9200 IPDU is installed inside marine navigation control cabinet, widely used on offshore supply vessels, drilling rigs, pipelay and hydrographic survey ships. It is legacy Fugro SeaSTAR GNSS interface controller for DP vessel high precision positioning.
