Orbit

[edit]

I've removed the orbital parameters from the infobox. Orbit was given as 621.7 km by 76.5 km, with a period of 91.4 min. I don't know where those figures came from, but they cannot possibly be correct; the perigee is too low for it to even be a stable orbit, and the apogee is far below that which would be expected for this class of satellite. --W. D. Graham 17:32, 29 April 2012 (UTC)[reply]

Thanks - I don't know how to sanity check these things. I thought it was from Podvig but he says『62.8 degrees and orbital period of about 702 minutes. Apogee of the initial orbit is about 39,000 km, perigee – about 600 km.』[1]. It might have got copied from Kosmos_2176 which has the same figures, which seem to come from NSSDC (http://nssdc.gsfc.nasa.gov/nmc/spacecraftOrbit.do?id=1992-003A). One of the reasons I've been hesitant about generating loads of stubs for these is that I don't understand how the Molniya orbit works. Secretlondon (talk) 13:20, 30 April 2012 (UTC)[reply]

I've added figures from Jonathan McDowell's list (http://planet4589.org/space/log/satcat.txt) which look more plausible. --W. D. Graham 16:18, 30 April 2012 (UTC)[reply]

Is the GRAU index of the bus necessarily wrong? 73D6 is US-K really. I can see that the name is friendlier but people do seem to write about these using the GRAU number more than they do in things like radar. Secretlondon (talk) 21:58, 2 May 2012 (UTC)[reply]
