Hi All, First, my apologies for sending the message I received from OIG this morning as an attachment in my previous message. I have included their response in the body of the present message: The daily TLE query limit applies only for orbital objects which are not available in the Special Interest group listings. The Special Interest groups contain listings for over one thousand (1,000) objects. The TLE queries are provided to assist our users that have specific interests which are outside of the Special Interest groups. We can accommodate a limited number of high volume TLE users. These high volume users must submit significant justification for their requirements and be approved by NASA Headquarters. Included in the special interest group is a amateur grouping of all radio and amateur satellites. System Admin -- Sincerely, Richard Fredrick rfredric@tfs.net Fairway, KS USA 39.021N 94.637W
