We’ve Redefined the Cost–Performance Curve
High performance GNSS protection is now required across all deployable platforms whether manned or unmanned. The operational environment is constantly changing, CRPA capabilities must be fitted to ALL platforms, not just high cost, exquisite.
High capability GNSS protection is no longer reserved for only the most expensive platforms.
GNSS resilience becomes scalable – not selective.
Anti-jam, low swap
Delivers advanced anti‑jam capability in a low‑SWaP form factor.
Affordable integration
Enables highly affordable integration across medium-cost platforms.
No Performance Trade-off
Removes the trade-off between performance and deployability.
Roke’s Nav-Sync Armour CRPA combines 40 years of PNT expertise with performance engineered for today’s operational demands – delivering scalable, cost-effective solutions that power autonomy across maritime, land, and air.
Designed for Fleet-Scale Reality
Modern missions rely on platforms that must be fielded in volume, not protected in isolation. This means protection moves from elite capability to operational baseline.

FAQs for NAV-SYNC ARMOUR
Yes. Nav-Sync Armour is designed to replace standard GNSS antennas and integrate easily with existing receivers.
Traditional CRPA systems are typically expensive, complex to integrate, and designed for a small number of high-end platforms. Their performance is strong, but their cost, size and integration burden limit their deployment.
Nav-Sync Armour delivers a different balance. Built on an digital CRPA architecture, it provides high-performance anti-jam capability, including significant suppression and the ability to handle multiple simultaneous jammers, in a compact, low-SWaP form factor.
The result is a system that maintains performance in contested environments but can also be realistically deployed across fleets of platforms, not just a select few.
Yes. Nav-Sync Armour is engineered to operate in dense, dynamic interference environments, including scenarios with multiple concurrent jammers. Using multi channel digital CRPA and advanced adaptive processing, it can suppress several independent jamming sources simultaneously while maintaining GNSS signal integrity.
This allows it to perform in environments where lower-element or legacy systems degrade.
Yes. Nav-Sync Armour is designed for platforms that rely on assured position, navigation and timing, including autonomous systems, as well as tactical air, maritime and land platforms.
It maintains GNSS reliability where interference would otherwise affect mission execution.
It is a UK sovereign, non-ITAR solution. Widely licensable to most destinations.
