The NavGuard® 420 from Mayflower Communications is a High Integrity Global Navigation System (HI-GAINS) GPS Anti-Jam Solution. It leverages operationally proven MAGNA GPS Anti-Jam solutions which have been integrated by multiple US Military and Government Agency platforms. This 4-channel anti-jamming solution utilizes a fully integrated CRPA antenna with integrated AJ electronics. It has a robust RF front-end that handles high-power co-site signals and provides simultaneous (L1 and L2) GPS protection. The NavGuard® 420 offers an affordable SWaP-C alternative over larger and more expensive existing anti-jam systems. It supports GPS protection requirements of the US Navy’s severely SWaP-constrained small UAS and handheld UAS platforms and is well suited for small rotary wing platforms, dismounted operators, and ground combat vehicles.
The NavGuard® 420 is C/A, SAASM, and M-Code compatible. It provides more than 40 dB of jamming suppression against multiple jammers and mitigates multiple CW, partial band, broadband, and pulsed jammers even under high dynamics. This system has been performance qualification tested by the US Navy NAVAIR and will undergo environmental testing to meet government technical requirement document (TRD) specification requirements. It is available in an enclosure that measures 2.60 x 2.60 x 1.19 inches and requires a DC supply of 28 V.
