Calian GNSS is launching its next-generation anti-jamming controlled reception pattern antenna (CRPA), the CR8894SXF+.
The CR8894SXF+ is purpose-built to provide efficient interference protection and real-time situational awareness across critical infrastructure, marine, and defense environments where GNSS continuity is mission-critical. The CRPA is specifically designed to offer a low-power, lightweight solution in a compact form factor.
Built for high-resilience applications, the CR8894SXF+ CRPA antenna employs advanced in-band null forming. This new surface-mount model is engineered to protect GPS L1/L2 and Galileo E1/E5b signals, ensuring resilient positioning, navigation, and timing (PNT) in contested, congested, and degraded RF environments.
Designed with Calian’s eXtended Filtering interference mitigation technology (XF+), the antenna delivers high performance and reliability in the presence of RF threats. The CRPA combines in-band null forming (20–40 dB) with powerful out-of-band rejection (up to 80 dB) from 700 MHz to 2500 MHz. It features two independent low-noise amplifier (LNA) channels—ensuring that if one signal band is compromised, the second channel maintains operational integrity.
The antenna forms nulls in both upper (L1/E1) and lower (L2/E5b) GNSS bands to actively suppress jamming sources. A built-in serial output interface provides real-time feedback, enabling users to monitor RF conditions and system status.
Outputs include:
- CRPA State: Open (no jamming), protected (jamming mitigated), or closed (jammed but protected)
- Jammer Characterization: Azimuth and elevation angles of detected interference sources
- Summary of Threat Signals: Rapid threat assessment for command and control
These features significantly enhance situational awareness, enabling system operators to maintain secure, uninterrupted GNSS-based operations in high-risk environments.
