The NavGuard 501® SAGE from Mayflower Communications is a GPS Anti-Jam System. It has a 5-channel design and provides simultaneous dual frequency (L1 and L2) GPS protection. This system utilizes a 3.5-inch diameter FRPA footprint and offers an affordable SWaP-C alternative over larger and more expensive existing anti-jam systems. It is a cost-effective alternative for use in GPS contested or denied (NAVWAR) environments and can drive multiple GPS devices from a single antenna and provide full functionality to all connected devices. The system is designed for the submarine OE-538B antenna system and is C/A, SAASM, and M-Code compatible. It also supports Iridium communications.
The NavGuard 501 mitigates multiple CW, partial band, broadband, and pulsed jammers even under high dynamics. It uses multiple-element spatial-temporal adaptive filtering (STAP) and provides jamming suppression against multiple types of high-power jammers. This anti-jamming system includes RS-232/RS-422 interfaces. It is available in an enclosure that measures 1.36 x 3.00 x 5.73 inches and is suitable for ground, marine, and submarine applications where clean GPS timing signals are required.
