Description

Small inclination synchronous communication satellite overlapping dual paraboloid ellipse field pattern antenna
Technical field
The present invention relates to a kind of small inclination synchronous communication satellite overlapping dual paraboloid ellipse field pattern antenna.
Background technology
Utilize the transponder on synchronous communication satellite, forward and be modulated with survey by what area navigation central station was launched Away from code and the carrier signal of navigation message, broadcast earthward, it is achieved the design concept of passive satellite navigation, It it is the central principle of CAPS system realization location.Forwarding more than needed on CAPS system synchronization telecommunication satellite Device, it is also possible to forward the signal of communication launched by ground satellite communication center, this is the logical of CAPS system Telecommunication function.
Earth stationary satellite by changing rail position and gesture stability, is made synchronous communication satellite drill by CAPS system Become the inclined plane satellite of small inclination, synchronous satellite is only implemented holding and the tune of longitudinal position Whole, do not make holding and the adjustment of position, latitude direction, allow it freely drift about in latitude direction.So, Fuel can be adjusted by the less attitude of satellite and keep the working track of satellite, greatly extend synchronous communication The service life of satellite.The 2nd the life cycle utilization thus opening up fixed service satellite is led Boat communications applications life cycle.Typically, CAPS system can extend synchronous satellite 5-8 in service life, Thus greatly reduce the communication cost of CAPS system used stationary satellite satellite.
From the point of view of location navigation, utilize the synchronization inclined plane that fixed service satellite drift is small inclination Satellite becomes the another class constellation of navigation positioning system, then can improve the space layout of constellation, reduces DOP value, improves positioning precision[3~5].Fixed service satellite becomes small inclination satellite and defends for relay type After star alignment system, its satellite orbit parameter remains a need for by surveying tracking system forecast.Fixed for satellite navigation Position is for the requirement of constellation, it is not required that satellite is strictly on equatorial synchronous orbit position, at latitude Direction has drift value more preferable on the contrary, and drift value is the bigger the better.Retired satellite does not make the control of latitude direction After system, satellite can be made every year to increase drift band in North and South direction, it is annual about that drift increases speed Changing between 0.75 °~0.94 °, the cycle of change is about 18.6a.The accumulative effect of drift makes satellite Orbit inclination angle the most constantly becomes greatly, and maximum can reach about about 14.5 °, the most again by The least, become the synchronization inclined plane aeronautical satellite of a small inclination.
But, when utilizing the transponder on CAPS aeronautical satellite to use as communication port, ground antenna needs Carry out ± 8 ° from motion tracking.This antenna just substantially increasing CAPS system-satellite earth station becomes Basis and fault rate.Accordingly, it would be desirable to a kind of new antenna is to solve the problems referred to above.
Summary of the invention
The present invention proposes a kind of small inclination synchronous communication satellite overlapping dual paraboloid ellipse field pattern antenna.This Bright purpose is achieved through the following technical solutions:
Small inclination synchronous communication satellite overlapping dual paraboloid ellipse field pattern antenna, described small inclination synchronous communication Satellite special overlapping dual paraboloid ellipse field pattern antenna is divided into two parts along axis, the first parabola and second Parabola, described first parabola and the second paraboloidal focal axis have angle with axis shape respectively;Described Small inclination synchronous communication satellite special overlapping dual paraboloid ellipse field pattern antenna is provided with an elliptical horn Waveguide, the mouth of pipe of described elliptical horn waveguide be arranged at comprise described first paraboloidal focus with At second paraboloidal focal position.
It is an advantage of the current invention that:
For overcome CAPS aeronautical satellite transponder communication function must by the deficiency from motion tracking earth station, This programme proposes the burnt antenna of fan, contains latitude ± 8 ° whole satellite drift track, makes CAPS system make The ground satellite station of communication can use fixing directional antenna.Decrease the complexity of ground antenna, fall Low antenna cost and maintenance difficulties.Make cheap CAPS system communication channel system, have phase therewith The cheap earth station equipment of coupling.

Fig. 3: the present invention is in horizontal 2D direction analogous diagram.
Detailed description of the invention
It is illustrated in figure 1 small inclination synchronous communication satellite of the present invention overlapping dual paraboloid ellipse field pattern antenna Structural representation.Small inclination synchronous communication satellite overlapping dual paraboloid ellipse field pattern antenna is divided into two along axis Part, the first parabola and the second parabola, described first parabola and the second paraboloidal focal axis are respectively Have angle with axis shape;Described small inclination synchronous communication satellite special overlapping dual paraboloid ellipse field pattern sky Line is provided with an elliptical horn waveguide, and the mouth of pipe of described elliptical horn waveguide is arranged at and comprises institute State at the first paraboloidal focus and the second paraboloidal focal position.If Fig. 2-3 is that the present invention exists respectively Vertical 2D direction, horizontal 2D direction analogous diagram.
Should be appreciated that the above detailed description carried out technical scheme by preferred embodiment is Illustrative and not restrictive.Those of ordinary skill in the art is reading the basis of description of the invention On the technical scheme described in each embodiment can be modified, or wherein portion of techniques feature is entered Row equivalent;And these amendments or replacement, do not make the essence of appropriate technical solution depart from the present invention The spirit and scope of each embodiment technical scheme.
