Geostationary Satellites
[attachment=26994]
Abstract
A chart is presented that allows for the rapid determination of the
azimuth and elevation to a geostationary satellite, given the satellite
longitude and the latitude and longitude of the ground site.
In the course of evaluating the usefulness of VHF
beacon transmitters on several geostationary satellites for
ionospheric#electron content measurements [1] -[21, it has
been found useful to have available a means of determining
at a glance the elevation and azimuth angles required for
the ground receiving antenna at numerous possible observing
sites. The chart derived for this purpose should be
useful as well to others in view of the general interest in
applications of geostationary satellites to areas such as
communications, air traffic control, and remote sensing.
The nomogram could be used, for example, to deternnine
quickly the range of satellite longitudes which, for a given
ground site, would result in an elevation angle greater than
a specifled minimum.
