CONTENTS
Annex 1 - Method for
calculating the minimum angle, subtended at the Earth’s surface, between a HEO
satellite within its active arc and the visible portion of the geostationary
orbit
Annex 2 - Calculation of increase in GSO link noise due to interference
from a HEO satellite at the start of its active arc
Annex 3 - Iterative implementation of the methodology in
Annex 1
Annex 4 - Examples of application of the methodology of Annex
1
Annex 5 - Method for calculating the minimum angle, subtended at the Earth’s
surface within the footprint of a beam of a geostationary satellite at a given
longitude, between that satellite and a HEO satellite within its active
arc
1 Plane geometry of an elliptical
orbit
2 Calculation of geographical coordinates of an
“active” HEO satellite
3 Calculation of minimum separation
angle
Annex 6 - Examples of applying of the methodology of Annex 5
