However there inclinations differed. Echo 1 was in an orbit inclined 47 degrees to the equator, and originally a circular orbit . Echo 2 was in an a polar orbit, inclined 81 degrees to the equator. You can see the characteristics of the original orbits by looking at the current orbits of the rockets which deposited them in orbit. I saw Echo 1 within a day of it acheiving orbit, and tracked it ( in daylight) to within a day or two of its demise.
