Mayflower Communications Company, Inc., the technology leader in small Size, Weight, and Power (SWaP) GPS Anti-Jam solutions for 40 years, today announced the release of the NavGuard^® 750 – Integrated M-Code Anti-Jam System (IMAS) — the industry’s most compact, fully integrated, and affordable Assured Position, Navigation and Timing (APNT) system with NAVWAR Situational Awareness (SA) capability.

Developed with sponsorship from the U.S. Space Force, Canadian Department of National Defence, and U.S. Navy NIWC Pacific, the NavGuard^® 750 was designed to meet the APNT protection requirements of the U.S. Department of War and Canadian Armed Forces, particularly for severely SWaP-constrained platforms. The system has already demonstrated successful performance in contested Navigation Warfare (NAVWAR) test environments.

The NavGuard^® 750 IMAS is well-suited for deployment on small ships, unmanned surface vessels (USVs), unmanned aerial systems (UASs), SWaP constrained ground combat vehicles, robots, and fixed-wing and rotary-wing aircraft, providing warfighters with resilient navigation and timing even under hostile jamming conditions.

“In today’s NAVWAR environments, GPS resilience is critical to mission success,” said Mr. Joseph Thomas, Senior Director Government Programs, Mayflower Communications. “The IMAS (NavGuard^® 750) provides the smallest, fully integrated, and combat-proven solution for delivering APNT to the warfighter.”

Technology and Integration

The NavGuard^® 750 builds on Mayflower’s operationally proven TRL 9 MAGNA-I GPS Anti-Jam solution, already integrated across multiple U.S. military and government platforms. The IMAS product integrates:

• MAGNA-I AJ solution within a Controlled Reception Pattern Antenna (CRPA) array
• Military GPS Receiver with simultaneous dual-frequency (L1/L2) support
• MEMS Inertial Measurement Unit (IMU) for short-term accuracy, spoofing mitigation, and operation during GPS outages
• Chip-Scale Atomic Clock (CSAC) for precision timing and rapid re-acquisition
• Additional Situational Awareness capability including Direction of Arrival (DOA) and Jammer Classification

The 7-channel Anti Jam design enables suppression of a wide range of narrowband and wideband jammers, while maintaining performance in high-dynamic environments, including countering rotor blade modulation.

Key Features and Benefits

• Compact 4.5” diameter CRPA footprint, NATO-standard FRPA mount compatible
• Greater than 40 dB jamming suppression across multiple simultaneous threats
• Jammer Direction of Arrival (DOA) and Jammer Signal Characterization for enhanced Situational Awareness
• Provides an external protected RF-output that supports CA, P(Y), or M-code GPS receivers with ability to split/distribute to multiple GPS Receivers simultaneously

Assured PNT for the Modern Battlespace

By combining anti-jam, precision timing, and inertial navigation technologies in a single lightweight package, the NavGuard^® 750 IMAS offers the most compact and fully integrated APNT solution available on the market today. Its rugged, connectorized design makes it ideally suited to protect critical platforms in the multi-domain operational environment. With its fully connectorized, lightweight, and SWaP-optimized design, the NavGuard^® 750 IMAS provides a mission-ready, affordable APNT solution for the next generation of multi-domain operations.

“As adversaries increasingly threaten GPS access, IMAS delivers a resilient, affordable, and mission-ready APNT capability to ensure warfighters maintain navigation and timing superiority in contested environments,” said Dr. Triveni Upadhyay, President and CEO, Mayflower Communications Company Inc.
