BORAJ-SLIM4 Dual-Band GNSS CRPA System
BORAJ-SLIM4 integrates a four-element antenna array with dual-band anti-jamming and anti-spoofing capabilities. It receives L1, B1 and E1 together with either L2 or L5, providing between 90 and 80 dB of suppression against one to three interference sources. The SAJ GNSS Shield can be added when a higher level of suppression is required.
Measuring 100 x 100 x 24 mm and weighing less than 265 g, the low-profile unit can be incorporated into compact defense-platform navigation architectures. BORAJ-SLIM4 is IP67-rated and Pixhawk-compatible, with NMEA 0183 output through a customizable Micro-D interface.
