LauncherOne rocket with C++ engine
summary
Description of the LauncherOne autonomous flight safety software: C++ codebase for an aircraft-launched rocket that must meet FAA safety constraints, uses template metaprogramming for a compile-time observer pattern, relies on ECC memory, lockstep and triple modular redundancy hardware options, and applies explicit initialization, enable_if checks and a safe-bool idiom to force compile-time or early failure. Emphasizes exhaustive unit/integration testing, simulated time acceleration, heavy telemetry retention on failures, and design choices made to maximize recoverable data rather than graceful continued operation.
