The Commercial Affairs Division of the Swedish Defence Materiel Administration (Försvarets materielverk – FMV) has awarded supply contracts to Raytheon UK (a business unit of RTX Corporation) for the procurement of Landshield and Landshield Plus GPS anti-jamming protection systems.
The acquisition enhances Assured Positioning, Navigation, and Timing (APNT) resilience across the Swedish Armed Forces’ (Försvarsmakten) land, naval, and airborne operational platforms. Designed to operate in high-density electronic warfare (EW) environments, the Landshield product family utilizes multi-element Controlled Reception Pattern Antenna (CRPA) technology to nullify intentional Radio Frequency (RF) interference, broad-spectrum jamming, and hostile GPS/GNSS spoofing vectors. This integration equips frontline tactical vehicles—including combat armors like the CV90—with uninterrupted satellite navigation and weapon-aiming capabilities during high-intensity conflict scenarios.

Landshield System Variants & CRPA Architecture
💥 Landshield Baseline (4-Element CRPA):
• Antenna Architecture: Integrated 4-element dual-tuned Controlled Reception Pattern Antenna (CRPA) array
• Nulling Capability: Digital beamforming creates directional signal nulls toward up to 3 simultaneous threat jamming sources
💥 Landshield Plus (7-Element / 10-Channel Advanced Variant):
• Antenna Architecture: High-density 7-element CRPA array housing both antenna and anti-jam digital processor within a single enclosure
• Advanced Multi-Jammer Protection: Processes up to 10 digital channels to defeat up to 9 simultaneous hostile jammers across multiple frequencies
💥 All-in-One Form Factor: Compact, platform-agnostic, low Size, Weight, and Power (SWaP) housing designed for rapid surface mounting on land vehicles, naval craft, and uncrewed aerial systems (UAS)
RF Threat Mitigation & Operating Frequencies
🚀 Protected Frequencies: Multi-band reception supporting GPS L1/L2 signals, Galileo E1, and SAASM/M-Code encrypted military positioning modes
🚀 Anti-Jamming Dynamics: Attenuates narrowband, broadband, continuous wave (CW), pulsed, swept, and spectrally matched hostile RF jammers
🚀 Integrated Anti-Spoofing: Advanced digital signal processing detects and flags fake GNSS signals (spoofing), alerting operators to deceptive RF vectors while maintaining position lock
🚀 Sensor Integration: Interfaces directly with standalone GPS/GNSS receivers, Inertial Navigation Systems (INS), battle management displays, and C4I communication architectures
TIMES OF DEFENCE ASSESSMENT
The FMV’s procurement of Raytheon UK’s Landshield anti-jamming technology addresses a critical vulnerability in modern network-centric warfare. Operational theaters in Eastern Europe and the Baltic domain have demonstrated the pervasive use of heavy electronic warfare, where high-power jammers regularly degrade unhardened GPS signals, disrupting tactical movement, drone operations, and artillery precision.
From an engineering and integration standpoint, the Landshield family provides an optimal solution due to its low SWaP and all-in-one CRPA architecture. By housing both the 7-element antenna array and the digital anti-jamming processor inside a single, sealed exterior unit, Landshield Plus eliminates the need for internal vehicle hull electronics racks or complex coaxial cabling runs. Combining automated digital beam-nulling with real-time spoofing detection ensures that Swedish mechanized forces (such as CV90 formations) maintain precise position, navigation, and timing (PNT) even while operating inside severe, hostile RF-denied environments.
