In addition, there is a description of the file formats contained in the tar/zip file files Mike mentions below in: ftp://ftp.stk.com/dist/satdb/README -----Original Message----- From: Mike McCants [mailto:mikem@freeside.fc.net] Sent: Thursday, June 18, 1998 11:44 AM To: SeeSat-L@cds.plasma.mpe-garching.mpg.de Subject: Re: Provision of Orbital Data I have discovered that the full 8000+ tle elsets are available in the STK ftp area. Apparently this "database" is updated once a week. The following paths are on the STK web page under "Satellite database". Then pick Unix or PC. Then pick stkAllTLE for STK 4.0. The "PC" path is: ftp://ftp.stk.com/dist/satdb/stkAllTLE40.ZIP This zip file contains 6 files totalling 3.4 Megs. The file with the suffix "tce" is 8000+ elsets totaling 1.1 Megs. This file has a time stamp of June 15 at 9:43AM. There is only one tle for each object. The file consists of 8199 tles in "2-line" form - there is no "name line" before each tle. The file with the suffix "sd" is 14479 lines of NCat, Name, Country, Inclination, etc. Many objects have "duplicate" entries. The "Unix" path is: ftp://ftp.stk.com/dist/satdb/stkAllTLE40.tar.Z This gets a compressed file (use Unix "uncompress") which produces a Unix "tar" file (use Unix "tar xf") which creates the same 6 files. The Unix files do not have DOS "CR" characters at the end of each line. Mike McCants
