Description
The AJU-X200 is the sixteen-element single-band array: 110 dB single-jammer suppression, 100 dB with seven jammers and 80 dB with fifteen jammers arriving from different directions simultaneously. Sixteen elements give it four times the spatial degrees of freedom of a four-element unit, which is what allows it to keep a fix in a saturated environment where a smaller array would be defeated.
Key features
- Sixteen-element array, 200 x 200 mm, 26 mm bare and 42 mm with heat sink.
- Single-jammer J/S >= 110 dB, seven >= 100 dB, fifteen >= 80 dB at -130 dBm.
- Up to fifteen simultaneous jammers across 0-360 deg azimuth and -10 to +90 deg elevation.
- 1200 g bare, 2100 g with heat sink; <= 35 W.
- J30J-15ZK + SMA; DC 12-36 V; IP65.

Frequently asked questions
What is the AJU-X200?
The AJU-X200 is a CRPA anti-jamming antenna. 200 x 200 mm sixteen-element CRPA with 110 dB single-jammer and 80 dB fifteen-jammer suppression – the highest null count in the single-band range.
What are the key technical specifications of the AJU-X200?
Per the datasheet: Position accuracy — <= 7 m horizontal, <= 9 m vertical (95 %, PDOP <= 4); Weight — <= 1200 g bare / <= 2100 g with heat sink; RF output — -55 to -70 dBm, 50 ohm, VSWR <= 2.0.
What environmental conditions is the AJU-X200 rated for?
The AJU-X200 is sealed to IP65 and rated -40 °C to +70 °C, so it can be mounted on the vehicle or platform exterior without a separate environmental enclosure.
What applications is the AJU-X200 used for?
Fixed sites and command vehicles operating in contested GNSS environments. Maritime platforms requiring sustained navigation under jamming. Timing infrastructure for power, telecom and finance. Trials and evaluation programmes needing a reference anti-jamming antenna.
