Core Key Features
1.Dual-Band Design: Beidou Short Message + High Precision Positioning
Covers BD-S (2491.75MHz) for RDSS bidirectional short message communication and BD-L for satellite positioning; supports real-time point-to-point data transmission, up to thousands of bytes per single message, ideal for remote offshore blind-area communication.
2.IP68 Full Submersible & Outstanding Saltwater Resistance
IP68 fully airtight sealing allows continuous submersion up to 50 meters. UV-resistant fiberglass radome plus 316 stainless steel fittings passes strict salt spray testing to resist long-term seawater corrosion and tidal erosion.
3.Underwater-Optimized RF Circuit & Anti-Interference
Custom-tuned internal low-noise amplifier offsets underwater signal attenuation; circular polarization structure restrains multipath interference caused by seabed reflection, ensuring steady satellite link under rough coastal hydrological conditions.
4.Compact Structure & Flexible InstallationStreamlined mini outline, available for screw fixing or hoop clamping on ROV shell and buoy casing, easy for equipment integration.
5.Customizable Wiring & Multiple Interface Options
Standard 10m waterproof RF cable; custom length 3m~100m available. Default SMA Female connector; N-type / BNC optional to match mainstream Beidou RDSS communication modules.
