GNSS and Inertial for Autonomous and Remotely Piloted Aircraft Systems
Maarten Uijt de Haag, Ohio University

Global Navigation Satellite Systems (GNSS) such as the Global Positioning System (GPS) are being used in a wide variety of applications in today’s society and are already an enabling function on many Unmanned Aerial Systems (UAS) or Remotely Piloted Aircraft Systems (RPAS). This course will first introduce the various UAS/RPAS application domains and operational environments. Then, this tutorial will describe the basic operation of GPS and other GNSSs, their error sources and modes of operation and the state of art in GPS technology. Next, we will discuss the UAS-specific applications of GNSS for the various operational environments and applications including standalone GNSS, differential and relative GNSS, and the use of GNSS in precise surveillance. Finally, augmentation methods will be addressed with a focus on inertial measurements (IMUs) to enable a guaranteed required navigation performance in, especially, GNSS-challenged environments.
