INAV Configuration: Utilizing GNSS without Barometer Anytime it comes to configuring a flight controller for drone uses, one of the primary factors is how to accurately determine altitude and pilot through the air. Two typical sensors used for this purpose are GPS (Global Positioning System) and barometer. However, what transpires when you want to use GPS for guidance but don’t have a altimeter on hand? Or, perhaps your altimeter is faulty or inconsistent? In this post, we will investigate how to adjust INAV (a well-known open-source flight controller software) to use GPS for positioning without depending on altimeter data. Understanding the Role of GPS and Pressure Sensor in Flight Controllers Before going into the minutiae of INAV configuration, let’s briefly discuss the functions of GPS and altimeter in flight controllers:
GPS: The GPS module provides location data, including latitude, longitude, altitude, and speed. This information is crucial for navigation, allowing the flight controller to determine the drone’s position, velocity, and direction. Barometer inav-use-gps-no-baro
