The GS25 GPS Antenna provides highly accurate and fast position and speed updates by combining multi-GNSS (GPS, GLONASS, WAAS/EGNOS/MSAS, Galileo-ready) with an integrated magnetic heading sensor. Its 32-channel receiver delivers data at up to 10Hz, ensuring smooth tracking and reliable overlay on charts and radar displays.

Magnetic Heading Advantage

Unlike basic GPS units, the GS25 includes a solid-state electronic compass that provides magnetic heading, rate-of-turn, heel, and trim angles via the NMEA2000 network. This ensures accurate boat orientation, even at low speeds or when stationary, a vital feature for precision navigation.

Durable, Easy to Install

Built for harsh marine environments, the GS25 is fully waterproof (IPX7), compact, and lightweight (0.14kg), with both flush and pole-mount options included. It plugs directly into any Simrad NS-series MFD or NMEAcapable network using the supplied NMEA2000 cable.

Connectivity & Performance

With a fast cold-start time (~50s) and position accuracy of 3m, the GS25 ensures reliable and responsive performance. It supports differential correction and network integration, consuming under 2W, delivering efficiency without draining power.
