readings into usable navigation data is a more complex task. There are some open source packages specifically designed to incorporate IMU data into an application. ArduPilot Mega (APM) is one such program specifically developed for autonomous drones. It supports both piloted and unpiloted (fully autonomous) flight and includes hundreds of GPS waypoints, camera control, and autonomous takeoff and landing. Because it’s open source, the IMU code is open for inspection and can be repurposed for other types of applications. The Robot Operating System (ROS) from the Open Source Robotics Foundation, is a flexible framework for writing robotics software. It is a collection of tools, libraries, and conventions that aim to simplify the task of creating complex and robust robot behavior across a wide variety of robotic platforms. ROS contains interface code for several IMUs to inform its navigation modules. Conclusion Many embedded applications require the ability to locate the system’s position anywhere on earth. GNSS receivers alone are not sufficient, but when complemented by IMUs, finer positioning accuracy and faster update rates are attainable.
