Re: TLE updater program

I was considering writing an open-source/cross-platform version of TLE Retriever, to allow for retrieving elements from other sources as well as other frequent post-processing steps.

What features would people like to see?

I’ve got this short list of post-processing items from Mike’s DOS utilities:
(XF6) Insert 42 character names into line 0 of TLE from reference file (mcnames)
(XF7) Update a tle file from another TLE file
(XF9) Filter out elements with "DEB" with a space before that string. 
    But tles with names containing SPELDA, SYLDA, TANK, DPAF, and COVER
    The leading 0 and space are removed from "line 0" of the spacecom 3 line tles.
(XF10) The leading 0 and space are removed from "line 0”
(XF11) Sort TLEs into ascending NCat order
(geteccen) Filter mean motion less than [8.0] and eccentricity greater than [0.1]
(getleo) Filter mean motion is greater than [5.0]
(getepoch) (output epoch of each elset)

Also looking at having an online query-able database of McCants and TruSat TLEs, similar to what space-track.org <http://space-track.org/> provides for their TLEs.
