Also the european weathersatellites Meteosat are spin-stable. The spin-rate. which is perpendular to the earths polaraxis, is used to scan the earth line by line, whereby a mirror is used to move the scanning line from north to south. see the ESA web site Greetings Leo ----- Original Message ----- From: Øyvind Stangenes To: SeeSat-L@satobs.org Sent: Wednesday, July 09, 2003 7:44 PM Subject: Satellite attitude Hello all This may be a stupied questions but.....anyway I have been reading about satellite attitude control, and read about "spin stable" attitude, but when I was searching for satellite that uses "spin stable" attitude control I found nothing..... Does anyone of you know of some satellite that uses this kind of attitude control. And does anyone know of what spin rate (RPM) it must have(as minimum).
