MISSION SOFTWARE / Q.T.E.A.M
N.3.X.U.S OS
The software backbone of the tactical edge.
N.3.X.U.S OS is SSX360’s software architecture for connecting hardware interfaces, application logic, perception, field communications, and accountable evidence.
FIVE LAYERS / ONE ARCHITECTURE
Clear boundaries.
Connected responsibilities.
The architecture organizes the software stack into five layers. Each has a defined role, with interfaces and evidence requirements considered across the whole system.
- 01 / HAL
Hardware abstraction
A common boundary between devices and software. The architecture separates device-specific access from the services that consume it.
Interface definitions · Device state · Data ownership
- 02 / KERNEL
Core services
The kernel design organizes resources, state, and execution boundaries. Defined responsibilities make dependencies visible during integration review.
Resource ownership · State boundaries · Execution context
- 03 / PERCEPTION
Structured observations
The perception layer is intended to turn incoming observations into structured information that other software components can interpret and review.
Input context · Consistent records · Reviewable outputs
- 04 / GUIDANCE
Application logic
This layer defines application-level requests and state transitions. Its place in the architecture connects software behavior with the record needed to review it.
Application state · Defined requests · Evidence context
- 05 / COMM
Field communications
The communications layer defines exchanges between participating systems and QFN. Interface review addresses message structure, routing, and synchronization requirements.
Message interfaces · Network context · Timing requirements
EVIDENCE THROUGH THE STACK
A record that carries context.
The Accountable Evidence Plane is part of the integration design. The objective is to preserve the relationship between an observation, the software context, and the resulting record so reviewers can follow what happened.
Explore Accountable Evidence Plane- At the interface
- Identify the source, configuration, and relevant input context.
- Across the software
- Connect state changes and requests with their supporting observations.
- For the reviewer
- Define record formats, verification needs, and the limits of the available evidence.
WITHIN THE SSX360 ECOSYSTEM
Software in system context.
N.3.X.U.S OS brings a software architecture perspective to sensing, field networking, and system assurance. Integration discussions start with the participating systems and their interfaces.
TECHNICAL ENGAGEMENT
Start with your interfaces.
A software briefing covers the architecture, intended integration points, evidence requirements, and the material available for review. Detailed designs and implementation information are shared through an agreed technical exchange.
