BORAJ-MINI4 GNSS CRPA System
sag
BORAJ-MINI4 is a compact four-element controlled reception pattern antenna (CRPA) system that protects mission-critical positioning, navigation and timing against GNSS jamming and spoofing. It covers L1, B1 and E1 frequencies together with either L2 or L5, suppressing one interference source by 75 dB and three sources by 70 dB. When paired with the SAJ GNSS Shield, unwanted-signal suppression can reach 95 dB.
Weighing just 230 g, the system is suited to airborne and mobile defense platforms where installation space and payload capacity are limited. With an IP67-rated enclosure, it operates from 12 to 15 VDC and provides NMEA 0183 navigation data through a customizable Micro-D interface with TTL signaling.
