    Hi all,
    I'm following the discussion about TLE distribution with great interest. I've 
    not been active as an observer recently because of a very heavy workload. Most 
    of my spare time put on space matters is devoted to maintaining my website which 
    is now a good reference among French-speaking amateurs.
    To save time while taking positional data on a satellite, I intend to build a 
    tracking system for my binoculars that could read azimuth and elevation data at 
    the same time as time data either at pre-determined time interval or at the 
    click of a button or trigger.
    I have a question though. Is there a program that use this kind of data directly 
    to calculate an orbit and generate TLE. To know if my efforts will be worth the 
    time and money, I'm asking if analysts prefer to use AD-dec data instead of 
    Az-El or if any format is OK for all analysts.
    Thanks in advance for replies.
    BTW, I will be in France between Aug. 20 and 25 to meet amateur astronomers and 
    satellite trackers.
