There are only a very few TLEs available for this cis-lunar satellite (see below); a dense data set such as you seem to have found could show much about lunar-solar perturbations and other effects in the middle heavens. Is there an orbital mechanic in the SeeSat audience who can convert the XYZs into TLEs? (I've grabbed the files from GSFC and can mail them as a zip file if necessary.) Now if someone could only find the Vela orbital data.... 1 06893U 75206.00037963 -.00001524 15 2 06893 19.7000 0.0000 0000000 0.0000 0.0000 0.08329727 03 1 06893U 78201.99998843 .00000000 00000- 00000- 01 2 06893 40.6270 66.0200 1718000 289.3500 26.6390 0.08287392 00 1 06893U 84105.99996530 -.00001668 25 2 06893 43.2680 322.1660 1179610 200.3690 88.6120 0.08205088 2655 1 06893U 98141.08333333 -.00001374 43 2 06893 31.8005 268.0870 1190631 45.6781 359.5000 0.08192639 6879 1 06893U 98152.04703115 -.00001750 60 2 06893 31.5801 267.4199 1197054 45.8195 322.8346 0.08192656 6880 ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
