Introducing the Calian CR8894SXF+: A Cutting-Edge GNSS Antenna
The Calian CR8894SXF+ is a state-of-the-art, four-element Controlled Reception Pattern Antenna (CRPA) designed to provide remarkable GNSS performance, especially in areas plagued by critically important radio frequency interference.This antenna supports dual-band GNSS signal reception, accommodating GPS L1/L2, Galileo E1/E5b, GLONASS G2/G3, and BeiDou B1/B2b. It is indeed engineered to effectively counteract up to two sources of interference or jamming simultaneously occurring. With its advanced eXtended Filtering+ (XF+) technology, the CR8894SXF+ achieves over 80 dB of out-of-band signal rejection across a broad frequency spectrum (400 MHz to 3000 MHz), ensuring the reliability of GNSS signals even in densely populated RF environments.
Advanced Technology for enhanced Performance
Integrating Calian’s proprietary Accutenna® technology with a low-power analog interference detection system, the CR8894SXF+ delivers a pristine RF signal that is fully compatible with standard GNSS receivers. Its robust, IP69K-rated casing is designed for surface mounting on a variety of platforms, including unmanned aerial vehicles (UAVs), ground vehicles, and various infrastructure setups. The antenna is equipped with dual serial interfaces (RS232 and RS422) that provide NMEA messages detailing jamming detection and mitigation status, jammer frequency bands, and directional information relative to the antenna, thereby improving situational awareness in critical applications.
