Kongsberg Seatex DGPS 464
Kongsberg Seatex DGPS 464 is a UHF radio correction receiver designed for Kongsberg DPS 232 DGNSS positioning system, used to receive RTCM DGPS correction signals from shore-based reference stations for offshore DP vessels. This UHF DGPS correction radio receiver captures UHF band differential correction data and transmits RTCM messages to DPS GNSS receiver to improve positioning precision for dynamic positioning operations. The UHF DGPS correction radio receiver supports adjustable UHF frequency channels, built-in signal strength monitoring, link fault detection and serial data output to the DPS positioning controller. The UHF DGPS correction radio receiver works as a dedicated local DGPS correction link for coastal offshore fields, offering stable differential positioning augmentation when satellite correction services are unavailable. The UHF DGPS correction radio receiver serves as critical positioning spare part for DP vessel DPS 232 system overhaul and offshore navigation positioning retrofit.

This DGPS 464 unit adopts aluminum enclosure, operating temperature range -15℃ ~ +55℃, powered by 24VDC marine supply. DGPS 464 covers UHF frequency band 440–470 MHz, 50Ω antenna interface, meets IEC 60945 marine environmental standards with resistance to vibration, salt mist and high humidity. DGPS 464 is a discontinued legacy unit, only surplus and reconditioned spare stock available, widely fitted on offshore supply vessels, drilling rigs and DP ships equipped with Kongsberg DPS232 positioning system.

As offshore differential positioning communication hardware, this Kongsberg Seatex DGPS464 delivers local RTCM correction data to guarantee high-accuracy position reference for vessel dynamic positioning. Kongsberg Seatex DPS series spare parts include DGPS464 UHF radio receivers, DPS232 GNSS receivers, MRU motion reference units, antennas and signal cables for DP positioning system maintenance. Kongsberg Seatex UHF DGPS correction receivers are trusted replacement units for legacy offshore dynamic positioning reference systems.
