    Maybe you could elaborate on what's happening for those of us who don't know how to read these TLE's. Just posting them isn't very informative.

    Thank You.

    I know Sixto is away from the forum again for a little while. I'm sure when he returns he will decode the TLE's for you all.

    perhaps one indicator would be an increase in period, which would indicate the satellite is rotating slow (i.e. moving west) in relation to the earth's rotation?

    It takes the earth 23h 56m to rotate one time (1 day) or rotates 1.002 times per 24 hour period. That's why we have an extra day every 4 years. The SAT has to rotate at that speed to stay at the correct location, and has been the whole time it's been in orbit.

    understood, but would the period stay at that constant while it is drifting west? i would think "no", because in the basic understanding, period is not instantaneous but rather a time difference between the current and previous position.

    i have no understanding satellite telemtry tracking, etc., but just a person trying to make an educated guess.

    EDIT: i guess i am wrong...looking back at past TLEs while the SAT was moving to the IOT position at 76, the period stayed constant. ignore my previous posts.

    Yes, I have been following revs per day (1.00273214). Stupidly or not, I would assume that the number would change when the satellite moves. As it moves higher or lower, the revs per day would change.

    That and there would be an explosion of posts indicating the move had started. :D

    Correct. Without using a propagator, just looking at the TLE. The period is now 1.00273214. The last 4 digits will wander just keeping the bird in the "box". The "7" could also turn into a 69xxx, but if it gets less than that, the bird is drifting west. I would expect to see the period 0.999xxxxx when in full drift probably a day or so after it starts.:goodjob:

    I have never watched a single episode of Star Trek, watched a single Star Trek movie or watched anything Star Wars related since the 3rd movie came out in the early 80's when I was too young to know any better. Therefore many of the references are lost on me.

    The closest I have ever come to geeking out on anything remotely Sci-Fi was when I used to watch Lost in Space as a child and while watching MST3K during my stoner years.:D

    Kids. Sheesh.

    I moved to Indianapolis in May 1977. First weekend in town and nothing to do. So, I drove across town to the Eastwood Theater, one of the last decent movie theaters during that era of "tunnel theaters" in the local shopping malls. I was there in plenty of time, I thought, for the 8pm showing of Star Wars, but that show was already sold out. So, I bought a ticket for the 11pm show and hung out in the parking lot with the rest of the movie go-ers. The doors finally opened for our show and we filed in past the huge speaker columns that had been erected in the back corners of the theater. When I saw those speakers, I knew we were in for a ride. The lights dimmed. That first orchestra hit blared from the sound system. The title flew onto the screen. Yeah, what a ride.

    I think I ended up seeing the first Star Wars about 6 times in the theater before the "wow" finally wore off. I kinda feel sorry for the kids of that generation who never saw it in the theater.

    You are correct, sir. Star Wars changed a lot of lives. Makes me wonder many rocket scientists and satellite engineers grew up with the Star Wars franchise.

    I don't care if it drifts or if a passing astronaut kicks the damn thing. I just want it to get there faster! :)
