Resilient PNT: when GPS lies, the operator should know

GPS jamming and spoofing are routine in contested airspace, and the dangerous failure is silent — a spoofed position that looks perfectly valid. If the whole picture is pinned to a coordinate that is a lie, every decision inherits the lie.

Demonstrated
  • NIST RMF 800-37
  • FIPS 180-4 / 186-5
  • NATO SAPIENT
  • DoDD 3000.09

DaggerOS™ treats position, navigation, and timing as something to be checked, not assumed. When GPS is jammed or spoofed, it flags the degradation so the operator knows the coordinate under the picture may be compromised, rather than trusting it blindly. BlackEcho™ factors PNT confidence into every recommendation that depends on location or time.

How DaggerOS handles it

The silent failure — a convincing but false position — is the one that ruins a decision. DaggerOS makes PNT integrity visible: the operator sees when timing or position is under attack and can weight the picture accordingly. Because the system is air-gapped and passive-by-default, it does not add new emissions to the problem it is monitoring. The Human Gate governs any effect, with PNT confidence in view.

  • DaggerOS — surfaces PNT integrity as part of the picture and records it.
  • BlackEcho — discounts recommendations that hinge on a degraded position or time.
  • Human Gate — the single authorization point, informed by PNT confidence.

Standards touched

Security and provenance align to NIST RMF 800-37, and the decision record is chained per FIPS 180-4 / 186-5 so a timestamp is defensible. Track exchange follows NATO SAPIENT. Human authority is held to DoDD 3000.09.

Where it fits

Resilient PNT is the backbone of gps-denied operations and any mission where a false position is worse than none. It is evaluated by SOF elements, program offices, and coalition partners. See gps-denied operations and the SOF view.

Evidence

Demonstrated under live, operationally representative conditions at T-REX 26-2 (May 2026) — PNT integrity carried through the fused picture during the counter-UAS and EW demonstration.

FAQ

What is the real danger with GPS spoofing?

A spoofed position looks valid, so a system that trusts it blindly poisons every decision built on it. The value is making that attack visible so the operator does not inherit the lie.

Does DaggerOS provide its own navigation?

The published claim is integrity, not a receiver product: it surfaces when PNT is degraded or under attack so the operator can weight the picture, rather than asserting a coordinate it cannot vouch for.

How does PNT confidence change a decision?

BlackEcho discounts any recommendation that depends on a position or time flagged as degraded, and the operator sees that confidence at the Human Gate.
