Platform

MAGNOM

Multi-Element Anti-Jam GNSS Technology for Navigation Operations and Monitoring

MAGNOM card stack. RF cards swap to match the application's band plan; the digital and baseboard tiers remain stable across configurations.

MAGNOM is the hardware side of the SERGEANT/MAGNOM pair — an entirely COTS-based, modular GNSS receiver platform developed by Northrop Grumman over the past decade. The design is deliberately obsolescence-resistant: processing, logic, and RF cores can be refreshed independently, without affecting the application software that runs on top of SERGEANT.

For PGM applications, MAGNOM is envisioned as a card stack. RF cards can be swapped to match the specific application's band plan and front-end requirements, leveraging Northrop Grumman's experience with wideband direct sampling and diverse RF front ends.

Hardware highlights

Heterogeneous compute

Xilinx Zynq UltraScale+ MPSoC — application CPU cores paired with programmable logic for hardware-accelerated signal processing.
COTS-based, modular

No purpose-built ASICs in the critical path. Modular processing, logic, and RF cores are individually upgradable.
Card-stack form factor

PGM configuration is a card stack — RF cards swap in and out to match application-specific band and front-end requirements.
Wideband RF, direct sampling

Built on Northrop Grumman's heritage of wideband RF front ends and high-speed direct sampling.
Anti-jam multi-element support

Supports multi-element antenna configurations for anti-jam operation in contested NAVWAR environments.

Form factors

The same SERGEANT software stack runs across several platform form factors. The MAGNOM card stack is the common hardware substrate; the outer enclosure and bus carrier adapt to the mission.

PGM

Weapon form-factor

The compact configuration developed for the PGM SDRx prototype — a card-stack receiver sized for Precision Guided Munitions integration.
EGI-M

Embedded GPS/Inertial — Modernized

The modernized EGI form-factor for ground and aviation platforms, replacing legacy closed-architecture EGI units with a SERGEANT-based receiver.
R-EGI

Resilient EGI

The airborne Open-VPX configuration (CMOSS 3U) for platforms adopting a modular, standards-based resilient EGI.
