The PNT Standards Consortium

Part of the Open Architecture Field Guide. All information is derived from unclassified, publicly releasable (Distribution A) sources.

The PNT Standards Consortium is the body that governs the open navigation standards pntOS and ASPN. Announced June 2, 2026, it moves those standards from single-owner control to shared industry-government governance. It is operated under ISTO and was founded by Leidos, IS4S, and TRX Systems.

What it does

An open standard that one organization controls is only as open as that organization chooses to keep it. pntOS had been stewarded by the Army, and ASPN originated with DARPA. Both were freely available, but a vendor building a product on them was betting on standards a single party could change. The Government Accountability Office had recommended that these standards be governed and sustained by consortia of government and industry, rather than by one owner.

The PNT Standards Consortium answers that. It places pntOS and ASPN under a multi-stakeholder body with shared governance, the same model that gives standards like SOSA and FACE their stability. The change is about who controls the standards and how they evolve, not about the technology itself. For anyone building on pntOS or ASPN, it lowers the risk that the ground shifts under them.

pntOS and ASPN moved from single owners to the PNT Standards Consortium in 2026, the same multi-stakeholder model that gives SOSA and FACE their stability.

Where it sits

The consortium governs the software and data standards of the PNT family: pntOS, the fusion software, and ASPN, the data format. It does not change what those standards do. It changes how they are maintained, moving them toward the consortium model used elsewhere in the open-architecture landscape.

The open PNT standards: ASPN and pntOS, used by R-EGI and Army systemsASPN is the shared navigation data standard. pntOS is the open fusion framework built on it. The Air Force's R-EGI and Army PNT systems both build on pntOS and ASPN, which are governed by the PNT Standards Consortium.R-EGIAir ForceArmy PNT systemspntOSopen fusion frameworkASPNshared navigation data standard

pntOS and ASPN, now consortium-governed, are the open PNT standards that R-EGI and the Army's systems build on.

FAQ

Why was consortium governance recommended?
The Government Accountability Office recommended that pntOS and ASPN be governed by consortia of government and industry, rather than by a single owner.
What does it govern?
pntOS and ASPN. It does not change what they do; it changes how they are maintained.
Why does it matter?
It moves standards that one owner controlled to shared governance, which makes them a more stable foundation for anyone building on them.
Who founded it?
Leidos, IS4S, and TRX Systems. It is operated under ISTO.
