BAE Systems unveiled its newest advanced M-Code GPS receiver for guided weapons and other small applications at the 2022 ION Joint Navigation Conference, which took place in San Diego June 6-9.

The Strategic Anti-jam Beamforming Receive r – M-Code (SABR-M) enables precise geolocation and strike capabilities in highly contested battlespaces. It delivers accurate position, velocity, altitude and timing data, as well as strong protection against GPS signal jamming and spoofing — critical capabilities for unmanned aerial vehicles (UAVs), precision-guided munitions (PGMs), and missiles in threat environments.

SABR-M integrates receiver technology with advanced antenna electronics in a small, hardened package designed to meet challenging performance requirements, such as weapons applications. It is the most capable integrated anti-jam GPS receiver and the first integrated M-Code receiver available for weapon systems, according to BAE Systems.

“We’re making our full portfolio of military GPS solutions M-code-compatible to meet warfighters’ need for reliable positioning, navigation, and timing data to achieve their missions,” said Doug Lloyd, director of weapon systems GPS at BAE Systems. “SABR-M enables small platforms with challenging environmental conditions to get where they’re going despite interference.”

The compact (4.5 inch x 6 inch x 1 inch) SABR-M meets size, weight, power, cost (SWaP-C) and thermal requirements for space-constrained military applications. It uses advanced beamforming technology to improve GPS signal reception and counter threat signals. SABR-M is form-compatible with previous generations of the field-proven SABR receiver, which are integrated on low-cost precision weapon systems and long-range cruise strike missiles.

SABR-M will be fully qualified for production by the end of 2022. Production will take place at BAE Systems’ modern facility in Cedar Rapids, Iowa, which is in the final stages of construction. The purpose-built 278,000-square-foot factory and research center will be home to 700 military GPS experts in BAE Systems’ Navigation and Sensor Systems business.

Mayflower Receives FAA Approval for Anti-Jam Antennas

Mayflower Communications Company has received technical standard order (TSO-C190) authorization from the U.S. Federal Aviation Administration (FAA) for both models of its MAGNA GPS anti-jam product.

Mayflower’s MAGNA GPS anti-jam products — MAGNA-Federated (MAGNA-F) and MAGNA-Integrated (MAGNA-I) — can be installed on both military and civilian aircraft. Both MAGNA products offer simultaneous L1/L2 protection and can protect commercial and military GPS receivers.

Mayflower’s MAGNA products build on the company’s SWaP-optimized GPS anti-jam antenna technologies, which are optimized for small size, weight and power (SWaP), including small antenna systems. The MAGNA products were developed with sponsorship by the U.S. Navy SPAWAR and further improved under the U.S. Army PEO AVN to support GPS protection requirements for SWaP-constrained air, sea and ground platforms, such as fixed-wing/rotary aircraft, ships, UAVs and tactical vehicles.

The MAGNA-F (NavGuard 710) has been extensively integrated, tested and flown in navigation warfare (NAVWAR) operational environments by the U.S. government on multiple aircraft platforms. MAGNA-F is the highest performance and smallest federated GPS anti-jam solution on the market in its class, utilizing a 3.5-inch-diameter controlled reception pattern antenna (CRPA) compatible with existing fixed radiation pattern antenna (FRPA) footprints.

The MAGNA-I (NavGuard 730) is a high-performance yet small GPS anti-jam integrated solution on the market, with a 4.5-inch diameter FRPA-compatible footprint. MAGNA-I simplifies platform integration and reduces lifecycle costs. The MAGNA-I integrated anti-jam solution (antenna array integrated with antenna electronics in a single module) is designed for platforms with difficult integration challenges.
