KONGSBERG GLK-100A Product Details
1. Product Overview
The KONGSBERG GLK-100A is a high-precision GNSS (Global Navigation Satellite System) receiver module tailored for marine navigation, offshore operations, and maritime surveillance systems. It serves critical roles in commercial shipping, offshore oil & gas, and coastal patrol applications—focusing on providing real-time, reliable positioning, velocity, and timing (PVT) data to support vessel navigation, dynamic positioning (DP), and route planning. These capabilities are essential for ensuring maritime safety, optimizing voyage efficiency, and complying with international maritime navigation standards (e.g., IMO SOLAS).
Integrating multi-constellation GNSS reception and advanced anti-jamming technology, the module maintains stable performance even in harsh marine environments (e.g., signal obstruction from offshore structures, electromagnetic interference). Compatibility with Kongsberg’s K-Nav and K-Pos automation platforms ensures seamless integration into existing maritime control systems, making it a core component for modern maritime navigation solutions.

3. Product Specifications & Features
3.1 Core Specifications
The KONGSBERG GLK-100A is optimized for maritime positioning diversity, supporting five major GNSS constellations to ensure signal availability even in challenging environments (e.g., near high-rise coastal buildings or offshore wind farms). Its RTK (Real-Time Kinematic) positioning accuracy of ±1.2 m meets the strict requirements of dynamic positioning systems for offshore vessels, while the optional 100 Hz update rate enables precise tracking of fast-moving maritime assets (e.g., patrol boats).
The module’s multi-interface design (Ethernet, RS422, CAN bus) allows seamless connection to shipboard navigation displays, DP controllers, and voyage data recorders (VDRs). The 316L stainless steel housing and IP67 protection ensure resistance to corrosion from saltwater and harsh weather, aligning with the durability demands of long-term marine operations.
3.2 Key Features
-
Multi-Constellation Reliability: Simultaneous reception of GPS, GLONASS, BeiDou, Galileo, and QZSS eliminates signal dependency, ensuring positioning continuity in GNSS-challenged areas.
-
High-Precision Dynamic Positioning: RTK accuracy and optional 100 Hz update rate support offshore DP systems and fast-vessel navigation, critical for safe berthing and offshore construction.
-
Maritime-Grade Durability: IP67 protection, 316L stainless steel housing, and 2000-hour salt spray resistance withstand extreme marine conditions, reducing maintenance costs.
-
Seamless System Integration: Compliance with NMEA 0183/NMEA 2000 protocols ensures plug-and-play compatibility with Kongsberg and third-party maritime automation systems.
-
Anti-Jamming Capability: Built-in signal filtering technology mitigates electromagnetic interference from shipboard equipment, maintaining positioning stability.
