About This Content

Fly real iNAV in SITL Forge. The built-in controller is replaced with iNAV firmware running on your PC — position hold, return-to-home and waypoint missions fly against simulated GPS, on 1000 Hz physics fitted to real bench data.

Requires the base app: SITL Forge - FPV Laboratory.

Connect in 3 steps

1. Install iNAV Configurator — the SITL is already inside, nothing to build
   
2. In SITL Forge: External FC → iNAV → Activate
   
3. Run inav_SITL --sim=rf --simip=127.0.0.1 --chanmap M01-01,M02-02,M03-03,M04-04

A one-time CLI block (copy-paste from the in-app guide) finishes the setup. iNAV Configurator can stay connected over TCP 5761 for live tuning.

What you get

• Lockstep RealFlight bridge — low latency, so a heavy quad flies on a normal tune
  
• Simulated GPS and compass — position hold, altitude hold, RTH, waypoints, auto-launch
  
• Sensor-failure simulation for failsafe testing
  
• Classic MSP HITL mode as a fallback
  
• Firmware can run on another PC or in WSL

Compatibility

You provide your own iNAV install (the SITL ships with the free iNAV Configurator); this DLC does not include iNAV binaries. Step-by-step setup is in the app. Tested with iNAV 9.0.
