On my web page at www.quiknet.com/~jvarney I have placed a schematic diagram of how I plan to structure a program for Windows called SatManager. I won't go into detail here. Essentially it is a relational database that will read, store, process and manage TLE files for you. I'm admittedly behind schedule with SatManager, but hey, what do ya want from freeware? :) Anyway, I'd like the basic struture of SatManager to be driven by a semi-democratic process. Which means I'll consider building in the features you want if I agree to :) So, take a look at the schematic and let me know what you think. -- Jim ------------------------------------------------------------------------------ Jim Varney | 121^ 23' 54" W, 38^ 27' 28" N | Sacramento, CA Member, SeeSat-L | Elev. 31 ft. | Member, Sacramento Valley Astronomical Society |jvarney@mail2.quiknet.com ------------------------------------------------------------------------------
