Description
Technical field
The utility model belongs to marine satellite antenna field, and in particular to marine satellite antenna.
Background technique
Most important one kind is exactly satellite antenna in satellite receiving equipment, that is, we daily described " pot ", be one
A metal paraboloid is responsible for for satellite-signal being reflected into the feed and tuner of focal point.The effect of satellite antenna is
The small-signal transmitted by satellite is collected, and is eliminated as much as noise.Except some multifocal antennas are by spherical surface and paraboloid group
Except conjunction forms, most of satellite antennas are usually parabolic.It is concentrated after the reflection that satellite-signal passes through parabola antenna
To its focal point.
In modern waterborne commerce, once ship offshore, just can only be contacted by satellite communication and the external world, therefore, satellite day peculiar to vessel
Line is almost the standard configuration of all oceangoing voyage ships, and marine satellite antenna is the satellite antenna being arranged aboard ship, by servo-drive
Motor drives antenna movement, to be always maintained at the tracking to satellite during exercise.It is calculated accordingly in order to what standard was cut
Horizontal angle, the elevation angle, polarizing angle, it is necessary to have an accurate direction sign, this direction sign is provided by the compass of built-in antenna
Accurate data, or external compass is connected by equipment interface.Then correct numerical value is calculated by antenna system,
Then system is by driving servo-driver to position antenna accurately.This antenna is also current most complicated to require technology highest
