The Simrad GS25 Antenna Module Pack is a rugged, all‑in‑one NMEA 2000 antenna solution that delivers precise position data and reliable heading information for confident marine navigation. Built to withstand demanding sea conditions, it combines a high‑precision GNSS receiver with an electronic rate‑stabilized compass to deliver smoother charts, steadier courses, and seamless radar overlays.
Why the GS25 stands out
- Multi‑GNSS with rapid updates: Tracks GPS and GLONASS with support for WASS/EGNOS/MSAS, and is Galileo‑capable via future software updates, giving you broader satellite visibility and better accuracy.
- Blazing TTFF and 10 Hz updates: Excellent time‑to‑first‑fix and high‑speed position updates—up to 10 times per second—so your map and radar stay in tight sync with your actual movements.
- Integrated electronic rate-stabilised compass: Provides chart stabilisation and accurate course over ground at low speeds, enhancing radar overlay alignment and navigation confidence.
- Rugged, waterproof marine design: Engineered for all marine environments, delivering dependable performance in spray, spray‑downs, and rough water.
- Flexible installation: Includes spat/pole mount and mounting hardware to position the antenna for optimal satellite reception on any vessel.
- Independent source selection: Any connected display can independently select this sensor as a source, improving redundancy and compatibility across your network.
In the box and setup notes: The GS25 package ships with all essential mounting components and the long data/power cable, so you can install it quickly in a location that delivers the best sky view. The design is purpose‑built for marine radar integration, so you’ll enjoy reliable position and heading data that enhances charting, radar overlays, and overall situational awareness on the water.
Who benefits most
Ideal for skippers of coastal cruisers, bay boats, and small to mid‑size fishing or support vessels that rely on precise positioning and heading for navigation, radar correlation, and chart accuracy. If you’re upgrading an older system or adding a robust, future‑proof sensor to an integrated NMEA 2000 network, the GS25 is a natural fit that enhances display reliability and data quality across multiple screens.
