BORAJ-MINI4 GNSS CRPA System
sag
BORAJ-MINI4 is a compact four-element controlled reception pattern antenna (CRPA) system that protects satellite navigation signals against GNSS jamming and spoofing. It supports L1, B1 and E1 frequencies together with either L2 or L5, and when paired with the SAJ GNSS Shield, provides suppression of up to 95 dB.
The compact unit is designed for integration into UAVs and other size- and weight-sensitive autonomous platforms. The IP67-rated system operates from 12 to 15 VDC and delivers NMEA 0183 navigation data through a customizable Micro-D interface with TTL signaling.
