Architecture defined
Open case study

Selected engineering scope

GNC Subsystem Prototyping

Guidance, navigation, and control prototyping with explicit autonomy boundaries and hardware-in-the-loop hooks.

Services

Capabilities across the system stack

Each service maps to a concrete problem class, contribution model, and output set - not a keyword list.

Primary focus

Systems Architecture & Technical Product Ownership

Translate mission needs into coherent hardware/software architecture, clear interface ownership, and a technical roadmap that retires risk in the right order.

Questions addressed

  • Where should responsibilities live across the stack?
  • Which interfaces are mission-critical?
  • Which unknowns should be retired first?

Typical outputs

  • System decomposition
  • Interface definitions
  • Trade studies
  • Technical roadmap
  • Verification strategy outline

Operating principles

01

Retire the highest-risk unknown first

Sequence work so the program learns the hard truths early - before schedule and hardware commitments harden around them.

02

Define interfaces before scaling implementation

Ownership, timing, and electrical/software contracts come first. Parallel work only accelerates after boundaries are explicit.

03

Validate across hardware and software boundaries

Treat bring-up, firmware, RF, and control as one verification problem. Failures usually live in the seams.

04

Design testability into the architecture

HIL hooks, diagnostics, and observability are architectural choices - not late test add-ons.

05

Preserve traceability from mission need to verification

Every critical interface and behavior should remain explainable from mission intent through test evidence.

Engagement
