NavGuard® 100*** is the smallest 4-channel Anti-Jam SAASM receiver designed for extreme size, weight, and power (SWaP) constrained military GPS applications requiring SAASM and high Anti-Jam performance. At less than two cubic inches (42 mm diameter form factor) and using a fraction of the power required by other GPS and Anti-Jam systems, NavGuard® 100 makes totally secure GPS PNT possible for the most SWaP-constrained military applications. NavGuard® 100 also features an application processor for customer applications, such as GN&C, DI/UTC, and ES. NavGuard® 100 is designed to withstand gun shocks of over 20,000 Gs and well suited for SWaP-constrained precision guidance projectiles and mortars.
The Mayflower NavGuard® 100 is offered through the United States Foreign Military Sales (FMS) program authorized by the Arms Export Control Act (AECA), as amended [22 U.S.C. 2751, et. seq.] Mayflower is authorized to sell this defense article and services to foreign countries and international organizations.
