The Calian CR8894SXF+ is a compact, four-element Controlled Reception Pattern Antenna (CRPA) engineered to deliver robust GNSS performance in environments with high levels of radio frequency interference. Supporting dual-band GNSS signal reception—including GPS L1/L2, Galileo E1/E5b, GLONASS G2/G3, and BeiDou B1/B2b—the antenna is designed to mitigate up to two interference or jamming sources simultaneously. Its integrated eXtended Filtering+ (XF+) technology provides over 80 dB of out-of-band signal rejection across a wide frequency range (400 MHz to 3000 MHz), ensuring the integrity of GNSS signals even in congested RF environments.
The CR8894SXF+ combines Calian's Accutenna® technology with a low-power analog interference detection system, delivering a clean RF signal compatible with standard GNSS receivers. Its rugged, IP69K-rated housing is suitable for surface mounting on various platforms, including unmanned aerial vehicles (UAVs), ground vehicles, and infrastructure installations. The antenna features dual serial interfaces (RS232 and RS422) that output NMEA messages containing jamming detection and mitigation status, jammer frequency band, and direction relative to the antenna, enhancing situational awareness in critical applications.
