Unmanned Aircraft Systems (UAS) provide a cheap, effective platform to measure carbon dioxide levels in the atmosphere. This project focuses on the development of an inexpensive unmanned aircraft and sensor system to detect CO 2 leaks through in-situ atmospheric measurement of CO 2 , primarily for the purpose of quantifying emissions from underground carbon sequestration reservoirs. The sensor system is developed around a Senseair K-30 FR -a lightweight, low cost NDIR CO 2 sensor that is proved to have results on par with much larger and more expensive sensors. The system records CO 2 levels and their corresponding GPS coordinates, as well as tertiary sensor data (atmospheric data, altitude, etc.), using an Arduino microcontroller. This package is integrated with additional UAS components and a variety of autopilots to demonstrate the capability to create a 3D map of CO 2 levels. The resulting data can then be analyzed to determine the areas of highest CO 2 concentration and identify the location and severity of a possible leak.

The integration of UAS into the National Airspace, although imminent, still presents several technological challenges. Before a sucessful integration can occur, it is necessary to demonstrate different technologies in traffic detection, traffic avoidance, and communications, as well as in the integration of those technologies as a single unit. For this purpose, NASA developed its UAS Airspace Operation Challenge; a Centennial Challenge aimed at the demonstration of these technologies. The challenge consists of developing a UAS solution that can navigate autonomously while detecting and avoiding traffic using ADS-B signals. EmbryRiddle Aeronautical Univeristy developed an entry to this challenge: a UAS consisting of a surrogate UAV, a ground station, and a data link. The traffic detection challenges are addressed by processing images collected from an array of cameras mounted in the wingtips, while the avoidance challenges are addressed with a series of path planning algorithms. For communication, a ground station was built and equipped with a data link for monitoring the aircraft's systems. The individual components were tested sucessfully, but flight test of the integrated unit is still in progress. The challenge was cancelled, but Embry-Riddle's entry remains a valuable asset for UAS integration technology.
