Furthermore, (iii) its orbital plane gave the satellite at apogee a velocity tangential to the ecliptic, helping it stay in the plasma sheet, rather than cut across it. ... Figure #1 Point A in this drawing is perigee (just above Kourou), B is apogee , the solid line perpendicular to the Earth axis is a cut through the equatorial plane, and its continuation parallel to the ecliptic represents a cut through the plasma sheet (not to scale). ...

Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. A low altitude polar orbit is widely used for monitoring the Earth because each day, as the Earth rotates below it, the entire surface is covered. ... A different choice was made for MAGSAT, orbited 1979-80 to survey the Earth's own magnetic field near its surface. ...

... 1Wills Accurate measurements of relative flux density have been made between frequencies of 468 and 5009 MHz for 300 radio sources selected from Parkes catalogue. ... Excluding the incertainties in scaling these flux densities to an absolute system, rms errors vary from 0.24 Jy and 2.4 % at 635 MHz to 1.8 % at 2700 MHz; uncertainties in "absolute" scaling are thought to be about 45 %. ... Some sources whose spectra may be useful for flux density calibration are noted. ...
