The GS25 GPS antenna is the an advanced antenna for any boat that requires extremely accurate and rapid vessel position and speed updates. Advanced 10Hz performance ensures highly accurate, smooth and instant position updating (10 times per second). The 16-channel receiver rapidly acquires a signal, provides consistent position accuracy and eliminates “jumping” on the display, ideal for high-speed powerboats. Unlike other position-only antennas, the GS25 provides magnetic heading for accurate boat direction at any speed and for radar/chart overlay. Compatible with WAAS, EGNOS, MSAS, GLONASS, Galileo and QZSS satellite systems. Get the most accurate location information, no matter where you are in the world! The GS25 easily connects to any Simrad NSS, NSE or NSO multi-function display or any NMEA 2000 network. It is fully waterproof and can be pole- or surface-mounted.
