Description
Technical field
The utility model belongs to marine satellite antenna field, and in particular to the marine satellite antenna that anti-rolling is rocked.
Background technique
Since man invented satellite, satellite communication just occur with the life of the mankind it is inseparable contact, such as satellite
TV, satellite broadcasting, satellite phone etc..Satellite communication is realized by synchronous satellite forwarding capability, and floor portion mouth is defended to synchronizing
Star emits relevant audio-video signal, this signal is descended acoustic vision signal, signal institute by synchronous satellite according to a certain direction
Capped region all can receive signal by satellite receiving equipment, watch program: a good satellite receiving equipment, for
The quality of satellite communication plays a crucial role.
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
Antenna.Since ship can generate displacement in the process of moving, marine satellite antenna needs timely adjustment direction, and direction
Adjustment need certain limit function, otherwise unconfined rotation seeks star and will cause inner antenna electric wire coiling, to make
At the damage of antenna, therefore satellite peculiar to vessel requires limiting device.
In addition, boat-carrying satellite communication antena is in practical applications, since at sea mobility and being waved by ship is brought for it
Antenna beam roll, satellite antenna must adjust self-view constantly to keep the optimum reception posture to satellite-signal, when defending
When star antenna tracking satellite-signal, transponder polarization direction is often deviateed in antenna polarization direction, causes signal fadeout and serious
Cross polarization interference.
Since marine satellite antenna is needed through largely sensing, electric control element, and pass through complicated driven Design ability
Realize tracking to satellite-signal, therefore, the higher marine satellite antenna of sensitivity, price is expensive；And due to a large amount of
Sensing, electric control element all weather operations, abrasion, aging speed it is fast, vulnerable to aquatic environment destroy, maintenance expense also compared with
It is high.
Ship is in real navigation, due to the fluctuation of water, it may occur that the rolling along beam direction rocks and along captain's degree
The pitching in direction is rocked；Since the length of ship is much higher than beam, rolling is rocked and usually to be rocked more than pitching seriously.Cause
This, mitigating the work for rolling and rocking can rock in Ship Design prior to mitigating pitching.Under normal conditions, in the rolling side of rocking
The ship of face qualification also implies that it meets the requirement that pitching is rocked.
In ship line navigation, marine satellite antenna, which need to only overcome to rock due to hull rolling, to be affected, and just can be generated
Preferable signal reception；In the design of marine satellite antenna, such as only consider that the rolling of ship is overcome to rock bring influence,
The material cost and complex degree of structure of marine satellite antenna can be greatly reduced, while can also ensure the signal of marine satellite antenna
Reception ability is not significantly affected；Based on this consideration, a kind of marine satellite antenna is proposed.
