When I try the TLE Discovery post oms-3 1 99999U 95195.79961896 .00073094 00000+0 30704-3 0 36 2 99999 28.4657 317.6196 0021186 160.5927 108.3986 15.89732482 206 In the program "seesat", it barfs with the message "error in file, can't use". I'm not sure what's wrong. Does anyone have a good TLE for Discovery? A girl scout troop wants me to calculate passes for them for the next week for Cimarron, New Mexico (Philmont Scout Ranch), 104 57.5 West, 36 27 North 6693 feet elevation They're leaving tomorrow, so if I don't calculate it in the next few hours it's too late... I'm hoping to find the time to create a mail-server to deliver locally tailored predictions using this program. It's the only one I know of that has public-domain C source that runs under UNIX... (Does anyone know of a better starting point?) I created a one-shot server a couple of years ago using "seesat" to help the NASA tethered-satellite group track SEDS-2 as it came down and the tether twanged and broke... a couple of dozen people at remote places all over the world used it to get predictions for their locations (locations that weren't listed in the "big cities" lists the NASA people were posting to sci.astro for example).
