Hello All, I've revised the vso "Where to Find Orbital Data" page (/getkeps.html) so that it includes a pointer to the US Naval Research Lab Web-page which provides periodic updated TiPS elements. In addition, I've added a pointer to Alphonse Pouplier's page where you can obtain TiPS elements in his elset visi.zip . Thanks for the suggestion Craig!
