There are some inconsistencies between > http://pao.gsfc.nasa.gov/gsfc/gnews/052600/052600.htm#cgro and > http://spaceflightnow.com/cgrodeorbit/index.html and current elset at Alan Pickup's site: GRO 7.7 5.0 4.6 4.3 d 55 487 x 481 km 1 21225U 91027B 00149.54294176 .00007277 00000-0 25715-3 0 8202 2 21225 28.4609 114.0473 0004497 174.8580 185.2013 15.27184231390411 The web sources give apogee as 508,510,511,512 km, elset and Orbitel gives 487 km. SpaceflightNow gives the first burn time as 02:54 UTC (EDT+5h), but remaining times as EDT+4h According to the elset above, apogee is passed 01:52. OTOH, there is no need to fire at apogee for a near-circular orbit. The first burn is probably to place the perigee (or the final 80 km height) at the right latitude for June 4. Perigees are given as 508,349,249,150 km (computed) 510,350,250,150 km vs. 356,253,150 km. There was also to be an engineering test burn on May 28. The elset above, epoch Apr 28 at 13 h UTC, is also the last available at OIG, and there is no indication of a change from the previous elsets, except natural decay. If the current apogee is accepted, the test burn neglectable, the 30 minute burns distributed as 9,7,7,7 minutes, and 349 km accepted as the new perigee height, Vec2TLE gives me: GRO -36.9 487 x 349 1 21225U 91027B 00153.07916667 .00018222 00000-0 25715-3 0 8214 2 21225 28.4609 90.0130 0101388 220.8940 180.3101 15.49471557390961 after the first burn, GRO -28.8 487 x 249 1 21225U 91027B 00154.11180556 .00070148 00000-0 25715-3 0 8226 2 21225 28.4610 82.7512 0176640 232.9526 180.3094 15.66861298391126 after the second. -- 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 -- -- SeeSat-L / Visual Satellite Observer Home Page found at -- -- http://www2.satellite.eu.org/satintro.html -- ----------------------------------------------------------------- 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
