SITL Forge - iNAV collection

About this bundle Fly real iNAV firmware over simulated terrain — waypoints, return-to-home, and all. Get SITL Forge - FPV Laboratory together with the iNAV Integration DLC at a bundle discount — design the airframe, then hand it over to the same firmware you'd flash to real hardware, with GPS and compass simulated so every navigation mode actually works. ---What's Inside SITL Forge - FPV Laboratory — physics-first quadcopter simulator with 1000Hz Jolt physics, virtual workbench, motor/prop/battery models calibrated to real bench data, and a built-in PID controller for instant flying. iNAV Integration DLC — software-in-the-loop bridge that replaces the built-in PID with real iNAV firmware running on your PC. MSP HITL link, 50Hz RC channels, and simulated GNSS and magnetometer feeding the firmware's navigation stack. ---Why Buy The Bundle Fly a position hold, a return-to-home, or a full waypoint mission — and watch it happen against 1000Hz physics instead of a kinematic stand-in. Build the airframe on the workbench, then fly it under real firmware. Same project, same physics, no context switch. Get a navigation mode wrong in the simulator instead of over a lake. Failsafes, sensor loss, and signal loss are all things you can simply try. Tune PIDs, rates, and filters against a model fitted to real motors and props, before anything gets flashed. ---How It Fits Together The base app ships with a built-in PID flight controller and the full physics, audio, OSD, debug graphs, and workbench tooling. The iNAV DLC adds a one-click mode switch that hands the airframe over to your own iNAV SITL over MSP — the same 1000Hz physics keeps driving the simulation, only the controller changes. The simulator synthesizes GPS and compass from the drone's simulated position and feeds them to the firmware, which is what makes iNAV's navigation modes come alive. The iNAV Configurator can stay connected while you fly, so you can tune live and watch telemetry alongside the simulator link. ---Nothing To Build You provide your own iNAV install — but there's nothing to compile. The iNAV SITL flight controller ships inside the free, open-source iNAV Configurator, so if you already have the Configurator, you already have everything the DLC talks to. In-app setup notes walk you through the one-time configuration. Tested with iNAV 9.0. This bundle does not include or distribute iNAV binaries. --- This product is an independent integration.
