Satellite information

Introduction

This section contains information on satellites in your region and includes:
•

Satellite coverage areas.

• Satellite coverage by geographic location.
• Satellite tracking information
Satellite coverage areas
The following satellite coverage maps do not guarantee coverage. This can
be affected by climatic conditions that may cause variation in the satellite
signal.

Climatic conditions

Atmospheric conditions that may cause a significant loss of signal level
include:
• Rain
• Snow
• Heavy fog
• Solar activity, e.g. sun spot and flare activity.
By far the most common of these conditions is rain. Rain drops in the atmo-
sphere will reduce the signal from the satellite, the heavier the rain the
higher the signal loss. The effect of this signal loss is that the antenna's
ability to remain locked to the satellite signal becomes severely affected. This
in turn means degradation or in some cases a complete loss of satellite
signal. When the amount of rain contained in the atmosphere decreases the
antenna will re-acquire the satellite signal.
