Multi-Band Subsea 4G Antenna with GPS, for Offshore Navigation & Seabed Topography Mapping
Product Overview： Solve inaccurate underwater positioning, delayed survey data transmission and unstable multi-signal synchronization in seabed mapping and offshore navigation projects with our Multi-Band Subsea 4G Antenna with GPS. This industrial integrated subsea antenna combines full-band 4G LTE wireless transmission and high-precision GPS satellite positioning in a single compact module, supporting real-time coordinate locking and low-latency data return for marine survey operations. Optimized exclusively for seabed topography mapping and offshore navigation scenarios, it adopts underwater low-attenuation signal compensation and multi-frequency anti-interference technology to minimize signal loss in seawater media. Equipped with genuine IP68 full submersible waterproof performance, marine anti-corrosion durability and sealed through-hull installation structure, it delivers synchronous stable positioning and high-speed data transmission, providing reliable dual-function signal support for marine geodetic survey, seabed terrain mapping and long-term offshore navigation monitoring systems.
Application field： - Seabed topography mapping, underwater terrain scanning and marine geodetic survey engineering - Offshore vessel real-time navigation, positioning tracking and sailing data transmission - Underwater survey equipment

Highlighted Core Features
1. Integrated 4G + GPS Dual-Band Multi-Function Design
Different from traditional separate positioning and communication antennas that cause signal interference and cumbersome installation, this industrial subsea antenna integrates full-band 4G network transmission and high-sensitivity GPS positioning functions. It supports global mainstream 4G/3G/2G multi-band coverage and high-precision GNSS satellite locking, realizing one-device dual-purpose for navigation and data transmission. Built-in dual-channel signal isolation technology effectively eliminates mutual interference between network and positioning signals, ensuring synchronous stability of real-time GPS coordinate output and 4G high-speed data upload. It simplifies equipment integration structure, reduces installation space and lowers overall deployment costs for marine survey and navigation projects.2. Survey-Grade Precision for Seabed Topography Mapping
Specially calibrated for professional seabed topography mapping and marine geodetic survey, this GPS subsea antenna features fast satellite capture, low positioning drift and high coordinate repeatability. It effectively corrects positioning deviation caused by seawater refraction, deep water pressure and marine electromagnetic clutter, meeting the high-precision data acquisition requirements of seabed terrain scanning, water depth measurement and offshore geographic data recording. It maintains stable and continuous positioning output during dynamic mobile mapping operations, ensuring accurate and traceable survey data for ocean engineering and topographic mapping projects.3. Low-Attenuation 4G High-Speed Subsea Data Transmission
Optimized for underwater medium signal transmission characteristics, this multi-band 4G antenna adopts high-gain signal amplification and loss compensation circuits. It greatly reduces signal attenuation caused by seawater absorption, suspended sediments and deep-sea shielding, solving the pain points of high packet loss and low speed of ordinary marine 4G antennas in underwater environments. It supports high-speed, low-latency and stable transmission of large-capacity mapping data, terrain scanning parameters and equipment status information, ensuring real-time return and timely analysis of seabed survey data for offshore engineering operations.4. IP68 Full Submersible Marine Industrial Durability
Rated with industry-standard IP68 full deep-water submersible waterproof grade, this integrated 4G&GPS antenna supports 24/7 uninterrupted underwater submersion and all-weather offshore open-air operation. The high-strength marine-grade polymer shell undergoes strict anti-UV, anti-salt spray and acid-base anti-corrosion treatment, which stably resists long-term seawater erosion, wave impact, water flow scouring and outdoor aging. The fully enclosed integrated sealing structure completely isolates water vapor, sediment and marine biological fouling, ensuring zero-drift positioning and zero-failure network operation in harsh deep-sea and offshore survey environments.5. Sealed Through-Hull Installation & Low-Power Long-Term Operation
Tailored for survey vessel hull penetration, underwater mapping equipment and offshore monitoring terminal assembly, this multi-band antenna adopts integrated locking and fully sealed through-hull structure. It realizes precise hole-position fitting and complete airtight fixation, thoroughly avoiding water leakage and signal instability caused by traditional open mounting methods. The compact integrated structure resists marine vibration and underwater flow impact without loosening or signal interruption. Adopting industrial low-power design, it supports ultra-long standby and 7×24-hour unattended continuous operation, perfectly matching battery and solar power supply systems of marine survey equipment and reducing long-term project maintenance costs.
