Course Description

Ae 105 abc. Aerospace Engineering. 9 units (3-0-6); first, second, third terms. Prerequisites: APh 17 or ME 18 and ME 19 or equivalent.
Part a (1st term): Introduction to spacecraft systems and subsystems, mission design, fundamentals of orbital and rocket mechanics, launch vehicles and space environments; JPL-assisted design exercise; spacecraft mechanical, structural, and thermal design; numerical modeling, test validation.
Part b (2nd term): Introduction to guidance, navigation, and control (GNC), measurement systems, Kalman filtering, system analysis, simulation, statistical error analysis, case studies of JPL GNC applications; preliminary discussion and setup for team project leading to system requirements review.
Part c (3rd term): Team project leading to preliminary design review and critical design review.

Autonomous Assembly of a Reconfigurable Space Telescope (AAReST)

Link to the Ae105 involvement in the AAReST project

For the second half of the course, students collaborate with each other, along with GALCIT researchers on the AAReST mission. Several design areas are stressed with this project: spacecraft analysis and design, optics/telescope design and testing, composite boom testing, telescope software architecture, and electronics design. Students make significant contributions to these design areas, ultimately furthering the status of the mission as a whole.

Homework Policy

Students are encouraged to discuss homework problems, strategies and may compare final results, but each one should write down their own solution.

Late homework within 24 hours will incur a penalty (30%), and won't be accepted after 24 hours delay. In case a deadline extension is needed, please send a request to the TAs.

Class Material

Lecture notes, supplement materials, homework and solutions are for personal use only. They should not be distributed without the consent of the instructors.
