NavGuard® 400* is the smallest 4-channel AntiJam Electronics designed for extreme size,
weight and power (SWAP) constrained military
or civilian applications requiring high anti-jam
performance. At less 1.4 cubic inches (42mm
diameter form factor) and using a fraction of the
power required by other anti-jam systems,
NavGuard® 400 guarantees makes totally
secure GPS PNT possible for the most SWaPconstrained military or civilian applications.
