Spacecraft Solar Arrays Training
Spacecraft Solar Arrays Training Course Description
This three-day Spacecraft Solar Arrays Training takes a bottoms-up approach to describe spacecraft photovoltaics from basic quantum and semiconductor physics through flight mission applications. The cell technology section evaluates available and future photovoltaic technologies. The panel section explores practical array design details. The systems section explores power regulation, system analyses, and mission applications. The course cites multiple real-life examples to illustrate the relevancy of the presented material.
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
