CR7712EXF Embedded GNSS Antenna with Interference Mitigation

Precision GNSS Reception in Challenging RF Environments

The Calian CR7712EXF is a compact, embedded Controlled Reception Pattern Antenna (CRPA) designed to deliver clean, interference-free GNSS signals in the upper GNSS band (1559–1606 MHz). It intelligently steers a single planar null to suppress jamming or interference, ensuring reliable signal reception.

Key Features

  • Interference Mitigation
    Utilizes advanced CRPA technology to form RF nulls in the direction of jammers, and eXtended Filtering (XF) to deliver over 80 dB of out-of-band rejection (400 MHz to 3000 MHz), with sharp band edges for precise filtering.

  • Clean RF Output
    Outputs a standard RF signal compatible with all Commercial Off-The-Shelf (COTS) GNSS receivers—free from interference and jamming signals.

  • Real-Time Signal Awareness
    Integrated serial interface provides real-time antenna status, including jamming detection alerts, enabling quick diagnostics and situational awareness.

  • Multi-Constellation Support
    Supports GPS L1, Galileo E1, GLONASS G1, BeiDou B1, and GPS M-Code on L1.

  • Compact & Lightweight Design
    Combines antenna, interference mitigation, and null-forming technology in a single, surface-mountable enclosure with MCX RF and serial connectors.

  • Low Power Operation
    Employs a patented low-power analog interference detection and mitigation method, powered by Tallysman’s Accutenna® technology.

Applications

Ideal for defense, aerospace, and high-precision commercial applications where GNSS reliability is critical—even in RF-dense or contested environments.
