>Fellow Seesat-ers, > >I have just finished working on the latest version of my two line >element maintenance program TLEMOP. Here is a quick summary of it's >features. > >The latest version is 1z, and you will find it in a file called >TLEMOP1Z.ZIP and is available at: > >ftp://ftp.physics.ox.ac.uk/pub/sat/programs/ibmpc/tlemop1z.zip (Thanks >to Neil Clifford). > >I am also looking for other host sites...any offers? > >TLEMOP will process files in any format, i.e. UNIX or DOS separators and >will maintain a database file with all the latest elements in it. If you >have enough disk space, then keeping the TLEMOP database file will help >considerably in its speed, because the building of the database file is >slow process (lots of indexes to create). Once you have a database file, >normal weekly updating with say the 4000+ ELyymmdd file is very fast. My >TLEMOP database file currently has 7998 elements in it and is takes >around 3.5 MB of disk space. > >Here are some of TLEMOP features: > >/a : find tle's Anywhere in update file(s). This is great for getting >elements out of Seesat-l messages, HTML pages, in fact, any type of file >can be processed, if there is an element in there, it will find it. This >is combined with a very intelligent satellite name finder. Most of the >time you will get the right name. Of course, if there is no name, the >international designator gets used. > >/f : Freshen existing elements only. I use this to keep a small >"visual.tle" file up to date from my TLEMOP database file. > >/m : keep Ted Molczan's data in line 0 of the TLE. > >/r : Remove elements older than specified number of days. This will >automatically delete old elements in TLEMOP's database file. > >/w : keeps the TLEMOP database file for later re-use. This option helps >considerably in making it run faster when you do updates on say a weekly >basis. > >/z : use Z value '2' for '+' in checksums if you have elements that use >this convention. > >/n? : intelligent satellite Name logic will automatically pick the most >meaningful name for satellites. It is based on the length of the name, >the number of alpha characters etc. > >/r? : select Report options. You can select any number of reporting >options. Example: You may want to report new elements only, /ra, would >do the trick. Elements that have invalid checksums, /rc. Others are /rd, >realtime Display of report on screen, /rn, elements with Newer epoch, >/ro, elements with Older epoch, /rr, elements removed with /r switch, >/rs, elements with Same epoch, /rv, report eVerything. > > /s? : select output file Sort sequence. The options available are: /sa, >mean Anomaly, /sd, Drag or Decay, /se, Epoch, /sf, same as input File, >/sg, apoGee, /si, Inclination, /sm, Mean motion, /sn, Name of satellite, >/so, Orbit number, /sp, Perigee, /sr, Reverse sort (descending), /ss, >element Set number, /st, eccenTricity, /sy, launch Year/nbr/seq. > >There are another 1/2 dozen or so more options that you will find fully >documented in the TLEMOP.DOC file that comes in the release ZIP file. > >I have also included a MOP.BAT file that will make it very easy to set >up a TLEMOP database and do weekly updates...all with just one command! >Full details can be found in MOP.DOC. For you existing users of TLEMOP, >please see the TLEMOP.DOC file, section 1z. for what's new in this >version. > >I hope everyone enjoys using TLEMOP as much as I have enjoyed writing >it. I do ask everyone who uses it and finds it of value, to just let me >know, there is no registration required, and I'm not asking for any >money. Let me know what new features you'd like, and what you don't >like. Enjoy. > >Kulbinder S. Kalirai > >kkalirai@nettally.com > >
