Designing CRPAs that are effective in suppressing GNSS interference whilst also delivering the antenna performance needed for high positional accuracy is far from simple, and especially so if the CRPA must be compact and fit within strict size, weight and power constraints to support a wide range of applications.

Helix Geospace set out to address precisely this challenge, developing the CRPxTM GNSS Anti-Jamming System.

CRPx-unit-cutout

CRPx uniquely delivers resilient GNSS and high positional accuracy in a simple, compact footprint

frequency-icon-orange

Unrivalled Resilient GNSS

  • Dual-band (L1/E1, L2/L5/E5a/M-Code)

  • >50dB suppression; J/S >100dB

  • In-band, adjacent band, high-power & multi-jamming scenarios (non-blocking)

  • Dovetails with GNSS receiver anti-spoofing algorithms for optimum resiliency

Class-leading Positional Accuracy

  • Beam forms for optimal satellite tracking

  • Auto-adapts to platform motion (pitch and yaw)

  • High phase stability enables use with carrier-phase GNSS (RTK)

  • Combats interference from multipath and clutter (L-band, RADAR signals etc.)

Universal Compatibility & Ultra-low SWaP

  • Plug-and-play without needing any complex cabling, bespoke integration, or configuration

  • Compact & lightweight (Ø120mm x 30mm; <500g)

  • Ultra-low power (mean <3W; peak <5W)

UK-EU-NATO-flags

Patented DielectriXTM technology developed in the UK, backed with full UK/EU/NATO supply chain provenance and trusted by global partners.
