Evaluation of an Inexpensive Alternative to a Lidar Based Aerial UAV Surveying Platform

(Georgia Institute of Technology, 2021-05-15) McNulty, Will

In this project, a UAV aerial surveying platform is built, integrated, and tested using inexpensive and readily available sensors. The goal is to evaluate its performance and accuracy in lidar-based mapping of terrain elevation, and to assess its potential for replacing commercial off-the-shelf lidar surveying platforms that are very expensive to purchase and operate. A fully integrated field test is performed on the experimental UAV, and the results of this test show that a standard GPS receiver does not provide adequate position accuracy to achieve most aerial surveying tasks. Next, a simulation of Real-Time Kinematic (RTK) GPS position accuracy is applied to the experimental data as a substitute for the standard GPS data, and this simulation shows that an upgrade to RTK GPS could provide sufficient accuracy for many surveying missions. Despite the potential improvement in accuracy using RTK GPS, there are some fundamental limitations of the low-cost experimental platform, especially with regards to the resolution and level of detail it is able to capture during a survey. With this in mind, the low-cost experimental platform has the potential to fill a niche for surveying missions that don’t quite require the full fidelity of an expensive commercial lidarsystem, but could benefit from the significant reduction in cost and complexity. Finally, some general practical aspects for the experimental UAV are discussed, including regulatory issues and other considerations for field work.
Exploratory Study of Interplanetary Trajectories for a Twin-Spacecraft Mission to the Ice Giants

(Georgia Institute of Technology, 2021-05-14) Jagatia, Bhavi

Uranus, and Neptune, the Ice Giants, can provide unique insights into the forma tion of the solar system, and answer pressing planetary science questions. A combined mission to both ice giants would provide double the science return than visiting an individual ice giant. This work aims to investigate feasible tra jectories for such a twin-spacecraft single-launch mission to the ice giants. The analysis considers chemically propelled trajectories and solves the Powered Multiple Gravity Assist global optimization problem. Recommendations are made for feasible trajectories based on , mission duration, and science return.
The Attitude and Determination Control Subsystem (ADCS) for the Tethering and Ranging Mission of the Georgia Institute of Technology (TARGIT)

(Georgia Institute of Technology, 2021-05-14) Harathi, Abhijit

The Tethering And Ranging mission of the Georgia Institute of Technology (TARGIT) is a CubeSat mission that aims to demonstrate target detection and tracking via LiDAR and other sensors. A 3U CubeSat will be deployed from the ISS. After going through system checkouts and other procedures, it will deploy and inflate a tetrahedron-shaped target. The CubeSat will image and track the target with sensors in order to keep it within its primary imager’s field of view. Once it is a certain distance away, the CubeSat will use laser ranging technology to detect the target. Throughout all this, the CubeSat will be going through other mission modes to charge up, occasionally reduce its angular rates and stabilize itself, and keep a certain pointing configuration. In order to achieve and transition between the different mission modes, TARGIT has an attitude determination and control subsystem (ADCS) that maneuvers the spacecraft to and maintains different pointing configurations based on the mission mode required. It uses sensors to determine its orientation and it uses actuators to change or maintain its orientation as needed.
