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 atmosphere will reduce the signal from the satellite, the
heavier the rain the higher the signal loss. The effect of his
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.
