AJAS-8 CRPA anti-jam GNSS receiver top view — Assured PNT for unmanned and autonomous defense systems

Mission assurance

Keep trusted PNT available in contested environments.

Keep control when the RF environment turns hostile

Multi-source jamming can make GNSS availability disappear at the worst possible moment. AJAS-8 forms up to seven nulls to suppress simultaneous threats and keep navigation usable.

Authenticate navigation data before it drives the mission

Galileo OSNMA authentication helps detect spoofed navigation messages, protecting the integrity of the PNT data feeding autonomy, command systems, and timing networks.

Protect more platforms within real budgets

AJAS-8 is built for mass deployment, giving integrators CRPA and receiver capability at a cost profile suited to fleets of UAVs, unmanned ground vehicles, and maritime systems.

Performance evidence

Protection scales as the jammer count rises.

AJAS-8 is specified for one CW jammer above 65 dB suppression, and demonstrated 39.2 dB suppression in a seven-wideband-jammer test. The result comes from the same test scenario: -55.5 dBm jammer input reduced to -94.65 dBm after suppression.

46 dB suppression against one wideband jammer
44 dB against three wideband jammers
39 dB against seven wideband jammers

AJAS-8 seven wideband jammer input level before suppression — Jammer input: 7 wideband jammers at -55.5 dBm

AJAS-8 seven wideband jammer level after suppression — Suppressed output: -94.65 dBm after AJAS-8

Where AJAS-8 fits

Built for mission-critical platforms that depend on trusted PNT.

Unmanned aviation

Resilient PNT for fixed-wing and rotary-wing UAVs operating beyond benign environments.

Autonomous ground systems

Position trust for robots, logistics platforms, and armored vehicles exposed to EW threats.

Maritime and coast guard assets

Navigation continuity for vessels that need dependable GNSS in congested or contested waters.

Critical infrastructure timing

Authenticated, jam-resistant timing support for telecom, energy, and financial networks.

AJAS-8 essentials

The receiver behind the result.

Plug-and-play integration with UART, 1PPS, and jammer-removed RF output helps new and legacy platforms add assured PNT without reworking the full navigation stack.
