Contribution of course to meeting the professional component

This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.

The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.

EMA 642 focuses on satellite dynamics and does not provide much in the way of instruction in ABET's supplemental areas (economics, environmental, etc)

Relationship of course to undergraduate degree program objectives and outcomes

This course primarily serves students in the department. The information below describes how the course contributes to the undergraduate program objectives.

EMA 642 provides a crucial component of education for students interested in the aerospace industry. It also provides the opportunity for students to work in groups on a team design project and to prepare a written and oral presentation of that work.

Assessment of student progress toward course objectives

Weekly problem sets
Three in-class hour exams
Group design project
Group presentation
