Embodiment Construction

[0030] The invention provides a low-cost and high-precision ku / ka multi-band satellite tracking control system, which includes a main reflector, a secondary reflector, a ku-band feeder, a ka-band feeder and a supporting device.

[0031] The secondary reflective surface is a frequency selective surface.

[0032] The Ka feed system is placed at the focal position of the main reflector, and the Ku feed system is placed at the focal position of the Cassegrain antenna, thereby ensuring the pointing consistency of the two frequency band antennas, and the support device is set at the main reflector On the edge of the surface, the ka feed device is supported at the focal point by the supporting device.

[0033] Both the main reflector and the sub-reflector share the Ku and Ka bands, and the sub-reflector of the dual-frequency satellite tracking control system adopts a frequency-selective surface, which has the function of reflecting Ku-band and transmitting Ka-band signals at the same...

Abstract

The invention provides a low-cost and high-precision ku / ka multi-band satellite tracking control system. The system comprises a main reflecting surface, a secondary reflecting surface, a ku band feed device, a ka band feed device and a support device. A new tracking mode is employed, under the condition that the tracking precision is kept unchanged, the number of feed networks is reduced, the volume and weight of the whole structure are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of satellite communication, a low-cost high-precision kuka dual-band satellite tracking control system, in particular to a low-cost high-precision ku / ka multi-band satellite tracking control system. Background technique [0002] Limited spectrum resources are one of the bottlenecks in the development of satellite communications. At present, most commercial satellite fixed services use C band (4 / 6GHZ) and KU band (12 / 14GHZ). With the increasing variety of satellite communication services and the increasingly crowded and saturated channel resources, the demand for high-frequency satellite communication services is urgent. The high-frequency frequency band has the advantages of wide available bandwidth, less interference, and small equipment size. The ka frequency band satellite communication system mainly has great advantages in providing two-way multimedia services. [0003] With the increase of the freque...
