CR7712EXF

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.
