The Garmin GPS 24xd Position Receiver and Antenna – White (Part Number 010-02316-00) is a high-performance marine navigation sensor utilizing multi-band GNSS technology to track dual-frequency L1 and L5 signals across GPS, GLONASS, Galileo, and BeiDou networks. Specially configured for NMEA 0183 legacy network integration (also known as the HVS version), it delivers sub-meter positioning accuracy alongside a high-speed 10 Hz update rate to ensure smooth, real-time position updates on chartplotter screens. The unit features an integrated magnetic heading sensor providing directional accuracy within ±3 degrees regardless of vessel speed, which stabilizes map orientation, eliminates screen spin while stationary, and optimizes radar and MARPA tracking overlays.

Housed in a UV-resistant, IPX7 waterproof white dome, the antenna operates on a 9 to 32 VDC power supply and supports multi-SBAS corrections (including WAAS, EGNOS, MSAS, and GAGAN) for reliable signal reception in challenging marine conditions. The package includes versatile hardware for under-deck, pole, or surface mounting along with dedicated NMEA 0183 interface cabling, offering a straightforward wiring solution for older systems and specialized marine electronics setups.
