Kongsberg Maritime’s Seatex DARPS Transponder is a new generation relative GPS (RGPS) positioning system responder developed based on advanced GPS technology. Its core function is to provide high reliability and precision relative position reference for offshore operation scenarios, such as ship and platform/FPSO loading and unloading operations. Through integrated design and intelligent communication protocols, it adapts to the multi device collaborative positioning requirements in extreme offshore environments.
Core positioning and technological advantages of the product
1. Core application scenarios
Specially designed for offshore operations that require precise relative positioning, with a focus on addressing:
Position monitoring during loading, unloading, and supply operations between ships and fixed platforms (such as FPSOs and offshore drilling platforms);
The relative positioning of multiple ships working together in the same area to avoid operational risks caused by collisions or positional deviations.
2. Key technological advantages
Mature technology accumulation: Kongsberg Seatex has over ten years of experience in the development of GPS maritime tracking systems. The responder integrates continuous iteration of technical experience with the latest GPS developments to ensure positioning stability.
Highly integrated: All electronic components, GPS antennas, and UHF antennas are integrated into a single physical unit, requiring only one power cord to connect and automatically start when powered on, greatly simplifying installation and maintenance.
Anti harsh environment capability: Made of polyethylene shell, electronic components are designed for harsh marine environments, with a protection level of IP68 (able to withstand short-term immersion in 10 meters of water depth), suitable for offshore conditions such as salt spray, humidity, and vibration.
Multi device collaboration capability: Based on the Time Division Multiple Access (TDMA) protocol, it supports up to 24 ships sharing the same UHF frequency, with an update rate as fast as 2 seconds per time, meeting the requirements of multi ship synchronous operations.
Core functions and working principles
1. Relative positioning workflow
Data collection: The responder has a built-in GPS receiver that captures L1 C/A code and carrier phase signals, while also having anti multipath interference function to reduce signal attenuation and ensure the accuracy of the original data.
Data transmission: GPS raw data and responder status parameters are transmitted to the DARPS 100 host system on board via a UHF wireless link (bidirectional communication); If the ship sends RTCM correction data, the responder can output DGPS positioning results, further improving accuracy.
Position calculation: After receiving data, the DARPS 100 system on board accurately calculates the relative position between the ship and the responder (and corresponding platform); A single responder can communicate with multiple ships equipped with DARPS 100 simultaneously, achieving collaborative positioning among multiple ships.
2. Core functional highlights
High precision positioning: Based on L1 C/A code measurement technology, combined with anti multipath interference design, it ensures relative positioning accuracy and meets the strict requirements for position error in offshore operations.
Intelligent data verification: By using reliable data protocols to detect and eliminate erroneous data, invalid results can be avoided from affecting RGPS operations, ensuring reliable positioning.
Remote configuration and monitoring: Key parameters of the responder (such as UHF frequency, GPS update rate, TDMA time slot) can be remotely modified through the DARPS 100 control unit or handheld controller on board, and all status parameters (such as power supply, signal strength, working mode) can be monitored in real time to prevent sudden failures.
Flexible frequency selection: Provides two UHF frequency bands (450-470MHz standard band, 868-870MHz optional band), with easily adjustable frequencies within the band to adapt to radio spectrum planning in different sea areas.

Device integration: Directly interface with Ethernet/serial field devices that support multiple protocols, collect device data for display, historical storage, and execute control tasks.
Control capability: Built in adjustment control, logic control, timing control, sequence control functions, supporting alarm detection and notification.
Hardware architecture: Adopting dual core ARM ® SOC processor with clear dual core division of labor:
Core 1 (Control Core): Run control software and DCS control network communication software, supporting fault-tolerant operations.
Core 2 (I/O core): Run device integration software, independently handle on-site device connections and status diagnostics.
Basic requirements: A host workstation with Foxboro DCS Control Core Services v9.3 or higher must be installed, and connected to the control network via 100Mbps fiber/copper Ethernet. It must have obtained ISASecure EDSA Level 1 security certification.
2. Key difference: FDC280 vs FCP280
Comparison item FDC280 FCP280

PIO bus support not supported
Core advantage: No FBM required, directly integrated with field devices compatible with traditional PIO bus devices
Network configuration plan
FDC280 supports both Ethernet and serial network configurations, divided into two modes: “simplex” and “fault tolerant”, to meet the redundancy requirements of different field devices.
1. Ethernet network configuration
Support direct connection to Ethernet field devices or connection to serial devices through a “protocol specific gateway” (to achieve Ethernet serial bridging), with three core solutions:
Configuration Type Applicable Scenarios Key Features
Simplex, a single FDC280 module for scenarios with low reliability requirements, does not require redundant connections and saves wiring costs
Fault tolerant – Independent network with high reliability requirements, on-site equipment requires independent redundant network dual FDC280 modules (left/right), connected to two independent Ethernet networks provided by customers, with module IP addresses that can be the same or unique
Fault tolerant – Shared network field devices without independent redundancy requirements (such as single port devices). Dual FDC280 modules share one Ethernet network, supporting single port device access and reducing network complexity
Note: It is recommended to use a management switch for easy maintenance and troubleshooting; The device can also be directly connected to the FDC280 motherboard without the need for a switch.
2. Serial port network configuration
Each module of FDC280 contains 4 independently configurable serial ports (supporting RS232/RS422/RS485), with a maximum support of 128 serial field devices (up to 32 devices per RS485 port). The core solution is divided into 2 types:
Non fault-tolerant (Simplex): A single FDC280 can be connected to a single port serial device through a “Terminal Component (TA)”, supporting RS485 multi station connection without a modem and RS232/RS422 direct connection.
Fault tolerant type: Dual FDC280 modules are connected to devices through TA and adapted to different port devices:
Dual port device: The left/right module connects the two ports of the device separately to achieve redundant communication.
Single port device: RS232 needs to be connected to two TAs through a Y-shaped cable; RS485/422 can be directly connected through a dual module TA sharing connection.

Fault tolerance mechanism and reliability design
The “fault-tolerant” core of FDC280 consists of dual module redundancy, independent diagnosis, and seamless switching, covering the control network, CPU, and I/O levels to ensure uninterrupted processes
The dual modules of the control network are connected through the backplane and share control network access (dual switches). Communication messages need to be matched bit by bit by the dual modules before being sent. When a fault is detected, the non faulty module takes over control without process interruption
Core 1 (control core) primary/backup mode, real-time synchronization status. When the primary core fails, the backup core immediately switches to primary dynamic mode
Core 2 (I/O core) independently diagnoses the connection status of dual core devices. When the main core fails and the backup core device is better connected compared to the backup core status, the main core resets and hands over the role
The main module on the I/O side is responsible for reading and writing I/O points, while the backup module monitors device connections through “heartbeat commands” and synchronizes I/O values in real-time. When the main module loses connection, the backup module seamlessly takes over without any process fluctuations
2. Maintain convenience
Hot plug support: Replacing the FDC280 module does not require disconnecting the backplane power supply, and does not affect the field I/O signal of another module.
Status visualization: The front of the module includes an LCD display screen (displaying module identification, role, hardware version, network status) and LED indicator lights (running status, Ethernet connection status), supporting the configuration of “letterbug” through panel buttons.
