## Description

iNAV is flight control firmware designed to manage the stability, movement, and flight dynamics of multirotors, fixed-wing aircraft, and rovers. It serves as an autonomous flight controller and GPS navigation software capable of executing waypoint missions and maintaining position and altitude hold.

The system integrates GPS and compass data to enable autonomous navigation and automatic return to home sequences during signal loss or sensor failure. It includes an on-screen display generator to render real-time vehicle status and warnings directly onto a pilot video feed, alongside a flight telemetry logger for high-frequency sensor data analysis.

The project covers a broad range of capabilities including unmanned aircraft stability through PID tuning, control surface mixing for diverse vehicle types, and emergency failsafe management. It also provides tools for hardware sensor detection, serial port management, and antenna tracker integration.

Configuration and tuning are handled through a graphical interface, with support for configuration backups and wireless connectivity.
