As I indicated in http://www.satobs.org/seesat/Nov-2001/0002.html there IS a required geometry, which depends on where the spin axis is pointing, and how the solar panels are oriented relative to the axis. As far as I know, there is no favoured direction (but the panels are often about 90 degrees from the axis) > Bjoern, how did you obtain that beautiful star chart with sat tracks? Is > it very difficult to do? The orbit program which I use at present gives a ... Rob Matson's SkyMap. Technically very easy to make one chart - just run the program and indicate name of a ConTroL file. Normally don't edit the ctl file - there is a menu system for setting location, time, map projection and centre, star and star name magnitude limit, TLE file, satellite magnitude -elevation -range -perigee limits... or which objects you want. http://users2.ev1.net/~mmccants/skymap64/index.html (The asteroid, hip* and tycho* files are optional, depending on your desire for faint objects) -- 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 -- ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www.satellite.eu.org/seesat/seesatindex.html
