Applied EM’s anti-jam GPS antenna, AJGPS045, has achieved a four-channel Controlled Radiation Pattern Antenna (CRPA) in a very small size, weight and power (SWAP) particularly suitable for airborne platforms. Its footprint is the same as a standard GPS Fixed Radiation Pattern Antenna (FRPA), the FRPA-3.
This is a key enabler to bringing greatly improved anti-jam performance to smaller platforms and to GPS-equipped platforms that have inadequate anti-jam capability.
When integrated with appropriate four-channel antenna electronics and a military GPS receiver, the AJGPS045 enables L1 and L2 anti-jam performance of typically >80 dB. This is achieved with a passive compact antenna (.7” x 4.6” x 4.6”) that weighs 9 oz.
