>I generally download the big files from the JPL site: >ftp://kilroy.jpl.nasa.gov/pub/space/elements/satelem > >Then I run the file through a program I wrote called tlesum, which reads >the TLE file and a file called visual.asc, which contains a list of Is everyone aware of the program I use, PASSUPDATE, by TS Kelso? It takes a new large list of elements, compares it to any number of current element lists, and quickly updates all the old elements. Fast and simple. Names are not touched. >Of course, it's a subject of some debate as to what constitutes "visual" - Visual is anything you see. For the list I made, VISUAL.TLE, published by Kelso, I wanted to include all naked eye visual sats. I chose mag 3.8-4.0 as the limiting mag. > It also generates a summary file with inclination, apogee/perigee, etc., >for the entire list of objects. >If anyone is interested, I can upload the program and visual.asc files to >the Oxford site. I'd like to see the program that makes the summary file. JRespler@InJersey.com or Jay.Respler@bytewise.org Satellite Tracker * Early Typewriter Collector Freehold, New Jersey
