Wideband capture. Narrowband precision.
The SPECTRA-E Series delivers advanced GNSS anti-jamming protection for platforms operating in electronically contested environments. Built around a 62.5 MHz instantaneous bandwidth digital architecture and an 8-channel CRPA configuration, SPECTRA-E enables simultaneous protection of L1, L2, and L5 GNSS signals across all major constellations.
By combining wideband GNSS capture with multi-channel spatial processing, the system can actively suppress interference while maintaining robust Position, Navigation, and Timing (PNT). The 8-channel architecture supports up to seven independent jammer directions, enabling effective mitigation of multiple interference sources occurring simultaneously.
Direct-conversion sampling brings the captured GNSS spectrum directly into the digital domain, where adaptive digital filtering precisely suppresses narrowband and structured jammers. This approach delivers high suppression performance without RF band switching or legacy single-band limitations, ensuring resilient GNSS operation even against adaptive jamming techniques.
Its ruggedised, low-SWaP enclosure and military-grade electronics make it suitable for UAVs, UGVs, naval platforms, land vehicles, and fixed installations operating in contested RF environments.
8-Channel CRPA with Multi-Jammer Suppression
Supports spatial mitigation of interference from up to seven independent jammer directions simultaneously.
Direct-Conversion Sampling Architecture
Brings the captured GNSS spectrum directly into the digital domain for flexible, phase-coherent processing.
Adaptive Digital Filtering
Precision suppression of narrowband, multi-tone, and structured jammers while preserving GNSS signal integrity.
High Suppression Performance
Designed to significantly reduce jammer energy at the receiver input under realistic operational conditions.
Optional EW-Oriented Capabilities (Configuration-dependent)
Jammer direction indication, interference classification, threat reporting, and mission system interfaces.
Ruggedised & Protected Electronics
Integrated over-voltage protection (OVP), over-current protection (OCP), and reverse polarity protection for operational safety and long-term reliability.
Military Standards Compliance
Designed to meet MIL-STD-461G (EMI/EMC) and MIL-STD-810H (Environmental) requirements.
The SPECTRA-E 4CH delivers the same advanced wideband digital architecture and multi-constellation protection as the 8CH model, optimized for ultra-low SWaP (Size, Weight, and Power) requirements.
Utilizing a 4-channel CRPA configuration, it provides robust spatial mitigation against up to three independent jammer directions simultaneously. It is the ideal solution for small-form-factor UAVs, loitering munitions, and man-portable systems that require mission-critical PNT resilience without the footprint of larger systems.
Like the 8CH version, it features direct-conversion sampling and adaptive digital filtering to ensure seamless L1, L2, and L5 protection.
