Abstract
The presented research provides an analysis of the implementation of an Inertial Navigation System (INS) to augment GPS navigation in small Unmanned Aircraft Systems (sUAS) when GPS is unavailable or inaccurate. The quality of the Inertial Measurement Unit (IMU) required to create a stable INS solution will be analyzed, and for how long that solution would remain valid. This is essential for an sUAS system, as the accuracy of the INS solution will degrade rapidly over time. Data has been collected using an sUAS platform to acquire readings from multiple selected IMUs, and the data is compared against the recorded flight path, GPS data, and developed models. This research will enable future research into creating robust sUAS capable of operating in GPS degraded environments, and make sUAS safer for their integration into the National Airspace.
