In the first class of this series, we focused on the role a satellite plays in an entire space system, including systems on the ground and the environments of Earth and space. But satellite design is also a lesson in compromise. There can be little flexibility in orbit selection. And depending on their size, they are subject to many constraints.

In part 2 of this series, we will take a closer look at how successful that orbit would be from the perspective of power generation. Before even launching a satellite, engineers need to understand how much power their solar panels can generate and how much power the on-board systems will consume. They must also consider if the batteries will be able to supply the systems at peak power draw. This part of the series will focus on analyzing the solar and power design of a satellite.

In this class, you will:

• Calculate the total power generated and consumed by the onboard system and learn how power generation changes over time
• Determine the optimal solar panel and battery combination to satisfy mission requirements
• Learn about the types of orbits and orbital elements, the relationship between satellites and ground targets, and determine how to optimize observation time between them

Engineers will be on hand to answer your questions live.

You can use STK Cloud, a web-based version of STK, to follow along with the instructor for this class. There is nothing to download in advance with STK Cloud. It does not require a license or software install.
