REM missions

REM instruments were operational aboard the UK small satellite STRV-1b and the Russian space station Mir

STRV-1b and Mir orbit
Orbits of Russian space station Mir and UK satellite STRV-1b

Satellite STRV-1b Mir
Orbit GTO LEO
Apogee [km] 36000 400
Perigee [km] 250 400
Inclination [degrees] 7 52
Period [hours] 10.5 1.5
REM operation Jun.1994 - Sep. 1998 Nov.1994 - Nov. 1996
The upper panel of the figure below shows the coverage of the two REM orbits in the B-L plane. The single hatched area is covered by Mir and the cross-hatched area by STRV-1b. The lines running from the upper left to the lower right indicate the location of the mirror points for particles with a particular equatorial pitch angle. Particles with pitch angles larger than the labeled values can not reach regions above the lines. So for example at L=5, only outer belt particles with equatorial pitch angles smaller than approximately 5 degrees can reach Mir - only a small fraction of the outer belt population.

The lower two panels show observed count rate L-profiles for several orbits.
