Underwater 4G/GPS Combined Antenna, High-Accuracy Positioning for Marine Depth Measurement
Product Overview： Solve inaccurate underwater coordinate positioning, delayed survey data transmission and signal crosstalk between separate communication and positioning antennas during marine depth measurement with our Underwater 4G/GPS Combined Antenna. This industrial integrated subsea antenna merges full-band 4G LTE wireless transmission and high-precision GPS GNSS positioning into a single compact module, enabling synchronous real-time positioning and low-latency survey data return. Exclusively optimized for marine depth measurement and hydrographic survey scenarios, it adopts underwater low-attenuation signal compensation and dual-channel anti-interference isolation technology to eliminate seawater signal loss and marine electromagnetic clutter interference. Equipped with genuine IP68 full submersible waterproof performance, marine anti-corrosion durability and sealed through-hull installation structure, it delivers consistent high-accuracy positioning and stable high-speed data transmission, providing reliable dual-function signal support for marine depth measurement, underwater topographic survey and offshore engineering exploration systems.
Application field： - Marine depth measurement, water depth monitoring and underwater elevation data acquisition - Hydrographic survey, seabed topographic mapping and offshore geographic information collection - Survey vessel real-time positioning

Highlighted Core Features
1. Integrated 4G + GPS Dual-Band Combined Design
Replacing traditional discrete 4G communication and GPS positioning antennas that cause bulky installation, complicated wiring and mutual signal interference, this underwater combined antenna realizes all-in-one integration of high-speed 4G network transmission and high-sensitivity GNSS satellite positioning. Built-in independent dual-channel isolation and frequency division filtering technology thoroughly avoids cross-band crosstalk, ensuring independent and stable operation of communication and positioning signals. The integrated modular structure simplifies equipment assembly, reduces hull and underwater cabin space occupation, and lowers overall deployment costs for marine survey systems, achieving one-device dual-purpose functional upgrade.2. Survey-Grade High-Accuracy Positioning for Depth Measurement
Specially calibrated for professional marine depth measurement and hydrographic survey missions, this GPS subsea antenna features fast satellite capture, low positioning drift and high coordinate repeatability. It effectively corrects positioning deviation caused by seawater refraction, water pressure changes and underwater terrain shielding, meeting centimeter-level and decimeter-level high-precision positioning requirements for water depth detection, seabed elevation measurement and underwater topographic mapping. It maintains continuous and stable coordinate output during dynamic mobile survey operations, ensuring every depth measurement data corresponds to accurate geographic positioning, greatly improving the authenticity and precision of marine survey data.3. Low-Attenuation 4G High-Speed Survey Data Transmission
Optimized for underwater medium signal transmission characteristics, this industrial 4G antenna adopts high-gain signal amplification and intelligent loss compensation circuits. It effectively reduces signal attenuation and packet loss caused by seawater absorption, suspended sediment coverage and deep water shielding, solving the pain points of slow transmission and unstable data return of ordinary marine antennas. It supports high-speed, low-latency and continuous transmission of large-capacity depth measurement data, scanning images and survey parameter information, ensuring real-time upload and timely analysis of marine survey data to improve overall survey operation efficiency.4. IP68 Full Submersible Marine Industrial Durability
Certified with industry-standard IP68 full deep-water submersible waterproof grade, this 4G&GPS combined 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, stably resisting long-term seawater erosion, wave impact, water flow scouring and marine biological fouling. The fully enclosed integrated sealing structure completely isolates water vapor and sediment infiltration, ensuring zero positioning drift and zero signal interruption in long-term marine depth measurement and offshore survey operations.5. Sealed Through-Hull Installation & Long-Term Unattended Operation
Tailored for survey vessel hull penetration and underwater survey equipment assembly, this dual-band combined antenna adopts integrated locking sealed through-hull structure. It achieves precise hole-position fitting and complete airtight fixation, thoroughly avoiding water leakage and signal instability caused by traditional open mounting methods. The compact and rigid structure resists marine sailing vibration and underwater fluid impact without loosening or signal deviation. 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 survey equipment, reducing long-term project maintenance costs.
Professional Application Scenarios
This high-accuracy underwater 4G/GPS combined antenna is widely applied in professional marine survey and depth measurement projects:Marine depth measurement, water depth monitoring and underwater elevation data acquisitionHydrographic survey, seabed topographic mapping and offshore geographic information collectionSurvey vessel real-time positioning, sailing track recording and survey data wireless transmissionOffshore engineering exploration, underwater infrastructure detection and resource survey positioningUnmanned survey boats, intelligent detection equipment mobile survey and data linkageCoastal water area monitoring, inland river depth measurement and water conservancy survey projects
