Product Description
AJAS-2 CRPA GNSS Receiver with Anti-Jam & OSNMA Anti-Spoofing
For applications requiring uninterrupted GNSS reliability, AJAS-2 protects your signals from jammer and spoofer. See how AJAS-2’s DSP-based Controlled Reception Pattern Antenna (CRPA) technology surpasses RF-based CRPA; for a detailed comparison, including how AJAS-2 excels in a 100W jammer GPS-denied scenario, visit our blog.
The AJAS-2 is a GNSS receiver integrating CRPA technology for jamming mitigation and Open Service Navigation Message Authentication (OSNMA) for spoofing protection, ensuring reliable Positioning, Navigation, and Timing (PNT) in GNSS challenged environment. The AJAS-2 is quite low-cost, suitable for high-volume anti-jam anti-spoof applications.
