Abstract

The present invention intends to realize high-quality wireless communication and optical communication using a conventional wind speed play apparatus.

A cell phone or a cellular phone using an existing base station requires a large amount of base stations to be connected to a wired network, which is expensive and complicated to construct a network. In addition, there are many areas where radio waves are shaded and are disconnected during a call. Due to the height of about 36,000 km, the subscriber terminal is very large and the price of the terminal is high. In addition, the cost of launch vehicles and satellites is very high and the number of locatable orbits is limited. The low-orbit satellite method has lowered the altitude to about 1,000 km, but the terminal is still large, the price of the launch vehicle and the satellites is high, and the subscriber terminal and the fee are relatively high. In order to solve this problem, a multilevel communication network such as terrestrial, telecommunication, space and so on is constructed by using wireless communication and optical communication by arranging communication lanes in a multistage arrangement in a top layer (a height of about 15 to 20 km)

It is possible to quickly and inexpensively replace a high-cost terrestrial wired network, enable broadband data communication, reduce the size and cost of the subscriber terminal, and reduce the communication fee with an efficient network configuration.

An important application of the present invention is to provide broadband data communication, multimedia communication, and high-quality personal mobile communication by constructing a high-speed wireless and optical communication network mainly for population density areas through communication.

The present invention is intended to realize high-quality wireless communication and optical communication provided by communication satellites using a conventional wind speed play apparatus. The main communication line has a size of about 25M and 30M and the sub communication line is 15M and 20M. It is equipped with a communication repeater such as S band, C band, Ka band and V band for spot beam, And provides telecommunication services mainly for urban population areas. Position the main communication line at the top of the troposphere (between the troposphere and the stratosphere) where there is a constant wind force (at an altitude of about 15 ~ 20 km) and install a secondary communication line at a distance from the main communication line. The main telecommunication provider provides mobile phones, broadband internet, etc., and the subcommittee provides multimedia, video conferencing, etc., or plays a role as a preliminary stage. [Figure 8]

The power supply is supplied through a communication link and the existing NiH _{2 is} used as a standby power supply.

In order to use the frequency efficiently in the primary radiator of the antenna, a combined beam array implementing a spot beam method is installed to transmit and receive S band and C band. It is possible to communicate in the space sector by installing a communication line or an inter-satellite antenna which can control one on the front side of the communication line and one on the rear side. Also, an optical transmission device is installed inside the communication line, and optical communication between the ground is made through the optical cable configured in the communication link.

The communication line is composed of a lightweight center wire and optical cable, a power supply cable for supplying alarms and a covering agent, a power supply for the center wire, optical transmission of the optical cable, and a module connection structure of about 50M do. In addition, several subordinate communication lines were opened to distribute the load of the communication linkage weight.

In order to control the altitude of the communication line, a windlass is installed in the ground control station to wind and loosen the communication line. In this case, if the communication line has a large tension, the communication line is loosened. In order to match the direction of the communication lead, a lower support is provided to enable the rotation of the windrass. [Refer to Fig. 7]

In order to maintain the balance between the wind force and the tension of the line, the communication line is designed to be longer than the length of the lower part by tilting the upper part of the telescopic body [see Fig. 1 to 6].

In order to maximize the power of the wind force, the wings of the telecommunication kite were made long and large and the long tail was attached to stabilize the direction of the telecommunication kite. In addition, two propellers and a rudder on the rear side of the telescopic wing were installed to control the posture of the telescope.

As shown in Fig. 6 (b), the two pairs of connecting rods can be rotated at the connecting port so that the connecting rope is not wound on the communication rope by the rotation of the subcommunication lead. As shown in Fig. 15, The communication line and the line were not interfered greatly.

As shown in Fig. 6, the lower part of the lower body of the body is longer than the lower part and the angle between the connecting line and the connecting line is made larger so that the body of the communication line is inclined to the wind force. Further, a connection line is further connected to the upper part of the body, .

The connection line support and the support of the first parabola radiator were made parallel to the wind direction so that the direction of the communication line was made constant and the head and tail of the communication line were made parallel to the lower and upper sides of the body bottom.

As a result, it is possible to manufacture a terminal that is much smaller than a conventional geostationary-satellite or low-orbit satellite subscriber terminal. In terrestrial wireless networks, there are many areas where radio waves are shaded. Especially, in the case of personal mobile communication using high frequencies, communication is interrupted by ground obstacles in many cases. Due to communication at a sufficiently high altitude of 15 to 20 km, Can solve such a problem. Broadband communication is possible by using optical fiber communication with the communication center. In addition, high-frequency communication can be performed between communications stations or between satellites so that multi-stage information communication can be realized. In addition, it is possible to construct a complex, high-cost existing wireless network existing in a simple and quick manner, at a low cost.
