Software-only simulation cannot fully expose timing errors, control instability, or real-world sensor effects in GN&C systems. This white paper explains why closed-loop, deterministic HIL environments are required to validate true system behavior—and how Missile TestBench Level 3 enables earlier, more reliable GN&C validation.

  • Why non-deterministic timing masks GN&C instability
  • How closed-loop HIL exposes issues software simulation misses
  • The impact of real-time synchronization and sensor latency
  • How early validation reduces late-stage cost and schedule risk

Get Closed-Loop GN&C Validation in Hardware-in-the-Loop Environments and learn how deterministic, closed-loop testing helps reduce risk before flight testing begins.
