KONGSBERG SEATEX TDMA 455 TRANSCEIVER MODULE G063-11_01

KONGSBERG Seatex TDMA455 is a L-band differential GNSS transceiver module for offshore dynamic positioning (DP) vessels, survey ships and offshore rigs. This L-band transceiver module receives L‑band differential correction signals from Fugro OmniSTAR satellite service, feeding differential correction data to the vessel GNSS positioning system to achieve decimetre-level accurate position reference for DP station keeping. This L-band transceiver module handles TDMA time‑division multiple access satellite correction data demodulation, signal quality monitoring and serial/Ethernet data output to DP control system and loading computer. This L-band transceiver module adopts marine-grade conformal coating, built for high vibration, salty and humid offshore environment.

This unit is a vital DP navigation spare part for offshore vessel and offshore platform navigation cabinet overhaul. The marine DP navigation spare part pairs with GNSS receiver antenna to obtain L-band correction data, eliminating normal GPS positioning drift. The marine DP navigation spare part monitors signal strength and correction data continuity, triggering fault alarms when L-band signal is lost. The marine DP navigation spare part can replace faulty transceiver module to restore high-precision differential positioning for dynamic positioning operation.

It delivers reliable L-band differential correction signal processing for offshore DP navigation systems. The L-band differential GNSS correction processing decodes L-band satellite correction message and transmits to GNSS main processor. The L-band differential GNSS correction processing provides stable position reference during offshore construction, survey and drilling operations. The L-band differential GNSS correction processing complies with offshore DP classification requirements for vessel station keeping.

TDMA455 module is rack-mounted inside navigation control cabinet, widely used on offshore supply vessels, drilling rigs and hydrographic survey vessels. It is original Kongsberg Seatex electronic spare part for legacy DGPS high-precision positioning system.
