The document discusses the parameters associated with satellite communications, including range, azimuth angle, and elevation angle, as well as their impact on coverage and link analysis. It addresses atmospheric degradation factors like rain attenuation and gaseous attenuation. Additionally, it highlights the lower earth problem in satellite positioning.

1. RANGE &
ANGLES TO
SATELLITE

2.  Range, azimuth angle, elevation angle &
height of ES.

3. Differential longitude

4. RANGE OF SATELLITE (GEO)
R- radius of Earth
.l-latitude or elevation angle
Z-longitude or azimuth

 Path loss.

6. ELEVATION AND AZHIMUTH
ANGLE

7. ELEVATION ANGLE TO SATELLITE
1) Evaluating atmospheric degration such as
•Rain attenuation.
•Gaseous attenuation.
•Scintillation (RF- solar wind)
2)Lower EA problem
