AXIS CRPA Antennas: 4E & 8E

High-Performance GNSS Anti-Jamming Antennas

Description

The AXIS CRPA Antenna Series provides a scalable, ruggedized front-end solution for assured PNT (Position, Navigation, and Timing) in contested electronic warfare environments. Designed to pair seamlessly with Kopplung Systems’ SPECTRA-E anti-jamming processors, these antennas enable robust spatial filtering to neutralize multiple simultaneous jamming threats.

The series is available in two distinct configurations to match mission requirements:

  • AXIS-4E (4-Element): A compact, low-profile “puck” antenna optimized for SWaP-constrained platforms such as tactical UAVs and loitering munitions. It serves as an ideal retrofit solution, fitting standard antenna footprints while neutralizing up to 3 interference sources.
  • AXIS-8E (8-Element): Available in Standard and Conformal (Curved) form factors, the 8-element version minimizes aerodynamic drag and radar cross-section (RCS) while offering superior resolution to null up to 7 simultaneous threats.

Features

  • Scalable Immunity
    Available in 4-element configurations (nulling up to 3 jammers) for tactical efficiency, or 8-element configurations (nulling up to 7 jammers) for maximum survivability against complex, multi-vector attacks.
  • Aerodynamic & Conformal Options
    Includes ultra-low profile flat designs for easy retrofitting and conformal (curved) shapes for the 8-element variant to perfectly match airframe geometry.
  • Full GNSS Spectrum Coverage
    Multiband antenna elements support all major global constellations, including GPS (L1/L2/L5), Galileo (E1/E5a/E5b), GLONASS, and BeiDou.
  • Ruggedized & Military-Grade
    Fully sealed, IP67-rated enclosures designed to meet MIL-STD-810H and MIL-STD-461G standards, ensuring reliability in extreme temperature, vibration, and shock environments.
  • Receiver Agnostic
    Engineered to work as a universal front-end, compatible with both Kopplung Systems’ internal receivers and third-party legacy GNSS systems.

AXIS CRPA Antennas: 8C

Conformal 8-Element Low-Observable GNSS Anti-jamming Antenna

Description

The AXIS-CRPA 8C is a highly specialized, conformal CRPA-antenna designed for next-generation aerial platforms where aerodynamics and low observability has crutial importance for the performance of the platform-system. Unlike traditional bolt-on “puck” antennas, the AXIS-CRPA 8C is engineered to integrate seamlessly into the platform’s skin, eliminating the drag and increased Radar Cross Section (RCS) associated with protruding sensors.

Featuring a high-performance 8-element array, it delivers the same superior anti-jamming capability as our standard 8-element variant, capable of neutralizing up to 7 simultaneous threats. This makes it the ideal solution for high-speed tactical UAVs, loitering munitions, and fixed-wing stealth aircraft that require assured PNT (Position, Navigation, and Timing) without compromising airframe performance or stealth characteristics.

Features

  • Seamless Conformal Integration
    Designed to match the curvature of the host platform, ensuring a flush aerodynamic profile that reduces drag and fuel consumption for long-endurance missions.
  • Low-Observable (Stealth) Design
    The non-protruding form factor significantly reduces the platform’s Radar Cross Section (RCS), making it suitable for operations in contested airspace where stealth is critical.
  • Superior 8-Channel Immunity
    Maintains the full spatial filtering capability of the AXIS series, nulling up to 7 simultaneous jamming sources.
  • Optimized Gain Performance
    Precision-tuned antenna elements compensate for the conformal geometry, ensuring high-gain reception of healthy satellite signals despite the low-profile integration.
  • Multi-Constellation Support
    Full coverage of GNSS frequency bands including GPS (L1/L2/L5 with M-Code support), Galileo (E1/E5a/E5b), and GLONASS, ensuring robust positioning redundancy.
  • Ruggedized & Military-Grade
    Fully sealed, IP67-rated enclosures designed to meet MIL-STD-810H and MIL-STD-461G standards, ensuring reliability in extreme temperature, vibration, and shock environments.
  • Receiver Agnostic
    Engineered to work as a universal front-end, compatible with both Kopplung Systems’ internal receivers and third-party legacy GNSS systems.
