Example tuTorial

Each week we present an example of an interactive tutorial from one of our online courses.

This week we present a 3-D interactive tutorial explaining circular LEO orbits. This is from course SBQ 401, Fundamentals of Orbits and Getting into Space, which explains how satellites are launched and how and why their orbits are chosen.

In the world of GEO satellite orbits, we only need to worry about the orbit location (longitude) and possibly inclination. But for LEOs, the parameters that define the constellation's orbits are completely different: RAAN (right ascension of the ascending node), inclination, apogee, and perigee. Constellations are typically organized into planes (by RAAN) and number of satellites per plane.

Click the blue "NEXT" buttons to step through this tutorial yourself, and experiment with the simulator! Be sure to try the "View from Site" selection when you are on Step 5 to see how your constellation appears from the ground.

Course SBQ 401 is included at no additional cost in the SatProf Training Membership. You can join and immediately begin learning about orbits, the business of space, and many other career-building topics.
