Ship navigation system GuardianGPS™ 5200

marinenavigation systemradar

Product overview
GuardianGPS protects a vessel’s position solution when GNSS signals are jammed, spoofed or degraded. Redundant multi‑band, multi‑constellation GNSS receivers, anti‑jam processing and continuous integrity monitoring maintain position outputs and alert the bridge if the GNSS solution becomes unreliable. The system is delivered with the SEALINK SLG‑1A active high‑gain marine antenna and can be supplied with a 5‑inch GuardianGPS 5200 bridge display for retrofit or direct integration.

Key benefits

• Anti‑jamming protection to reject interference and spoofing.
• Independent GNSS channels running in parallel with automatic switchover to preserve continuous position outputs.
• Continuous integrity monitoring with bridge alerts for navigation decision support.
• Standard NMEA outputs and bridge‑ready interfaces for direct connection to navigation, radar and ECDIS.
