NAIS-500 with GPS-500 GPS Antenna: Integrated AIS Safety for Busy Waterways

The NAIS-500 from Advance Trident delivers a streamlined, all-in-one AIS safety solution that marrying a Class-B AIS transponder with a built‑in GPS antenna. Engineered for modern, congested harbors and high‑traffic corridors, this compact unit keeps your vessel visible and your navigation precise without the clutter of separate boxes and antennas.

Why this all-in-one solution stands out

• Integrated Class-B AIS transponder with seamless send and receive of AIS data, so other vessels and coastal traffic easily see your vessel on compatible chartplotters.
• GPS-500 GPS antenna included ensures reliable, continuous positioning data that feeds AIS, onboard displays, and connected navigation systems for accurate routing and collision avoidance.
• Compact, lightweight, fully waterproof design built to endure marine environments and fit tight installations on smaller to mid‑size boats.
• Low power consumption with a wide voltage range for flexible installations across diverse electrical setups, reducing impact on battery life and power budgets.
• Extensive networking capabilities enable smooth integration with NSS, NSO, or GO series chartplotters and the Simrad RS VHF system for unified navigation and communication.
• Single‑box installation eliminates the need for separate GPS receivers or AIS boxes, cutting wiring complexity and setup time while delivering a cohesive marine electronics ecosystem.
• Class-B approval supports contemporary vessel traffic management, enhancing situational awareness in busy ports and lanes.

Real‑world benefits and use cases

For skippers and crews who value safety, reliability, and a tidy cockpit, the NAIS-500 with GPS-500 is a practical upgrade. In busy shipping channels, it provides real-time AIS visibility of nearby vessels and precise position data that feeds chartplots and displays in service of proactive collision avoidance. The integrated design shines when you’re docking in crowded harbors, navigating through narrow channels, or running commercial routes where space and simplicity matter.

Ideal for and compatible ecosystems

• Vessels that rely on NSS, NSO, or GO series chartplotters benefit from a single, cohesive AIS/GPS package.
• Operators using Simrad RS‑VHF systems gain synchronized navigation and communication data, reducing setup time and maintenance.
• Boat owners seeking a compact, professional-grade safety platform that pairs with existing marine electronics for enhanced situational awareness.

What you get and how it helps your voyage

• Integrated safety and navigation data—AIS visibility, precise positioning, and real‑time target plotting across your displays.
• Streamlined installation—one integrated unit replaces multiple boxes, simplifying wiring and reducing installation hours.
• Reliability in motion—robust marine construction and waterproofing keep performance steady in rough seas and changing weather.
• Future‑proof connectivity—networking options ensure your system scales with your chartplotters and VHF configuration.
