Calian’s CR7712EXF embedded Controlled Reception Pattern Antenna (CRPA) GNSS antenna steers 1 planar null to mitigate interference or jamming signals in the upper GNSS band (1559 – 1606 MHz). The output of the CR7712EXF is a standard RF signal (compatible with all Commercial Off The Shelf (COTS) GNSS receivers) with the interference/jamming signals removed. The CR7712EXF also has a serial interface that provides antenna state information indicating jamming detected or not. This feature allows the user to quickly understand the GNSS signal status.

The CR7712EXF utilizes the patented Tallysman Accutenna® technology and a new very low power analog interference detection and mitigation methodology. The product integrates the antenna, interference mitigation, and null forming technology into a light weight and compact enclosure.

The CR7712EXF is a 2-element CRPA designed for single-band Global Navigation Satellite System (GNSS) signal reception. It supports: GPS L1, Galileo E1, GLONASS G1 and BeiDou B1 signal bands. The wide bandwidth antenna elements support the GPS M-Codes on L1.

Intentional and unintentional interference or jamming can saturate a standard GNSS antenna’s Low Noise Amplifier (LNA) such that it may not provide a usable signal. Calian’s CR7712EXF employs two interference mitigating technologies: eXtended Filtering (XF) and Controlled Reception Pattern Antenna (CRPA). XF provides > 80 dB of out of band rejection from 400 MHz to 3000 MHz. Additionally, XF has very sharp band edges around the GNSS bands. CRPA technology creates radio frequency nulls in the direction of the interference/jammer and as a result the antenna provides a clean GNSS signal.

The CR7712EXF embedded CRPA is surface mounted using screws. A standard antenna radio frequency MCX connector and a serial interface connector are the interfaces provided.

Trust Calian to provide a clean RF signal in a noisy RF world.
