Engineering notes for complex systems.

Data links

Link resilience is a system property.

Range matters, but a dependable mission link is shaped by the full chain—from antennas and waveform to networking, interfaces and integration.

Resilient navigation

Protected GNSS begins before the receiver.

A front-end protection architecture can strengthen an existing navigation stack while limiting software and platform change.

Systems engineering

Open interfaces create longer-lived systems.

Mission technology evolves. Stable interfaces make it possible to improve capability without repeatedly rebuilding the platform around it.
