Steam Store description

This DLC adds a software-in-the-loop bridge between SITL Forge - FPV Laboratory and iNAV firmware running on your PC. The built-in PID controller is replaced with the real firmware, so you fly, navigate, and tune against the same code that runs on real hardware — driven by the simulator's 1000Hz physics model, calibrated against real bench measurements. Requires the base app: SITL Forge - FPV Laboratory. --- What This DLC Adds MSP-based HITL bridge — the firmware drives the simulator through iNAV's standard MSP_SIMULATOR protocol Per-motor outputs polled from the firmware, smoothed into the 1000Hz physics step 50Hz RC channel link — joystick or RC transmitter feeds the firmware's stick inputs Simulated GPS and compass — unlocks iNAV's navigation modes: position hold, altitude hold, return-to-home, waypoint missions, and auto-launch One-click mode switch — flip between built-in SIM and external firmware in-app --- A Controlled Environment for Navigation and Tuning iNAV is built around navigation, and so is this integration. Test GPS-driven flight modes and tune the firmware in a simulator that aims to approximate real airframe behavior as closely as possible — without risking hardware on every change. The behavior you see is driven by the same firmware code you'll flash to your aircraft, running against a physics model fitted to real bench data. Fly position hold, return-to-home, and waypoint missions against simulated GPS Iterate on PID gains, rates, and filters without crashing real hardware Probe failsafe behavior by simulating sensor and signal loss Reproduce t…
