I subscribe to STS elsets, and I also retrieved some ISS and Soyuz TM-31 elsets from OIG. Converted to comma-separated one-liners by my 'oneline.exe' I loaded them into Excel for graphing mean motion vs. epoch date. It is quite obvious that reboosts where made around Epoch 041.2 (COLlision Avoidance), 042.8, 044.8, 046.8, and 048.8 (separation) If these reboosts were single-burn, it is easy to get accurate times of reboost using Rob Matson's COLA or AllCola programs. However, the 42.8, 44.8 and 46.8 epochs refer to singular elsets between stable series of MM values, so they may be inaccurate, or imply that the reboosts were made in perigee/apogee pairs, possibly separated by some orbits. I may lack some elsets at the latter points, so I have submitted a 'Historical TLE Request' to OIG. -- bjorn.gimle@tietotech.se (office) -- -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- -- COSPAR 5919, MALMA, 59.2576 N, 18.6172 E, 23 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- > I'm trying to figure out when the docked Shuttle and the ISS maneuvered in > their orbit between Feb.13 and Feb.16. > ----------------------------------------------------------------- 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
