Since mike is an expert in sat tracking, he knows what he's talking about. Thought I am not to happy about some of his comments. I wish thank Dr TSKelso since without his SGP4/SDP4 code observing sats would be very difficult as it is used in our tracking programs and I believe to generate an orbit using mikes fitelem and other simular programs. I have tried to make positional onservations and also take observations and use his program to improve an orbit, I fail. I leave it to others to do the work, its way to difficult for me. Thanks to mike, ted and others for the work you do in generating orbits for classified objects. While what the datum and position is not important in sat observing, its very important for other things such as lunar occultations. For lunar occultations they need to know what datum you used and your position should be accurate to 15 meters in order for your observations to be useful. And even a 100 meters difference in positions does make a difference in lunar occultations. Now its time to end the tak about datums and geodetic position and talk about visual sat observing. And lets stick to that please. Thank You.
