During the last lesson, you might have been enlightened with the information that even though the Soviets have used, and Russians do use, geosynchronous (GEO) orbits for satellites, they seem to have a special place in their vodka-filled hearts for the highly elliptical orbit (HEO). And that last lesson enumerates the reasons why they like it. For one particular […]Read More Why Space Matters: HEO Satellite Operations, Part 4–Moley, Moley, Moley, Molniya!
In previous lessons you’ve learned about the Low Earth Orbit (LEO) and the Geosynchronous Orbit (GEO). There are pros and cons in using each orbit. Generally for satellites in LEO orbit, particularly imagery satellites like those owned by DigitalGlobe and SkyBox, the closer the satellites are to the Earth, the more detail of the objects […]Read More Why space matters: HEO Satellite Operations, Part 1–You’ve Never Kepled?
“…You gotta reach out – Reach out and touch someone…” The last lesson showed how a geosynchronous (GEO) satellite can essentially “hover” over a particular area of the Earth. Almost as if a physical rigid connection keeps them moving together. This is because the GEO satellite’s orbit matches the speed of the Earth’s rotation, giving […]Read More Why Space Matters: GEO Satellite operations, Part 4–Communicate
“Endless Distance, Wildlife and Stars, Blanket the Night…” The last lesson was about Field of View (FOV) and Field of Regard (FOR). It was intended to help with understanding the next few lessons regarding satellites in geosynchronous orbit (GEO). All mentions of GEO on this blog, unless otherwise stated, refer to a particular type of […]Read More Why Space Matters: GEO Satellite operations, Part 3–Revolution Earth
In the first lesson, you learned (if you didn’t already know) a spacecraft in geosynchronous orbit is very far away from the Earth—a little over 26,000 miles. Before going any further, an explanation of Field of Regard (FOR) versus Field of View (FOV) is in order since we will initially be talking about weather imagery satellites. […]Read More Why Space Matters: GEO Satellite operations, Part 2–FOV/FOR-it things
