Hi Tom. Interesting question. I wonder if running a prediction program forward from a set of 'todays' keps will give a vaild answer for decay date? Looking at the keps, you have a number for decay rate. I reached the conclusion that this could be a major source of inaccuracy as presumably

Gents, Gpredict has simple formula based the tle for the decay date. That is starting to appear elsewhere for visualization purposes. The negative altitude is the result of running past where the data is valid. Charles On Oct 13, 2011 6:44 PM, g0...@aol.com wrote: Hi Tom. Interesting
