It is a satellite antenna device that can serve as a backup and may be configured to include a satellite antenna panel 100, a panel supporter 200, a servo motor 300, and a communication module 400.

Specifically, the satellite antenna panel 100 is a flat satellite antenna, and may be formed by having waveguide horn antennas arranged in a certain plane direction. At this time, each waveguide horn antenna is formed by an independent combination of a small waveguide horn and a mini antenna, and can support dual frequency, dual polarization, and dual communication, and because the RF (radio frequency) transmission loss in the waveguide is low, it can be used with a general parabolic reflector. It can provide much higher efficiency than antennas.

The panel support 200 is a support that supports the satellite antenna panel 100, and has a space inside to accommodate a servo motor 300, a communication module 400, a GPS 500, an electronic compass 510, which will be described later. In addition to the displacement sensor 520, a main board (not shown), a power supply device (not shown) that supplies power from external power or a built-in battery, etc. may be embedded.

Here, the GPS 500 can check the location of the satellite antenna panel 100, and the electronic compass 510 can check the direction of the satellite antenna panel 100, so the satellite antenna panel measured through the GPS 500 Using the position information of (100) and the azimuth information of the satellite antenna panel (100) measured through the electronic compass (510), the azimuth, elevation angle, polar angle, etc. are calculated more precisely, and the satellite is operated through the servo motor (300). If the antenna panel 100 is controlled so that the signal is focused on the satellite, more precise pointing can be performed.

The communication module 400 is a means for communicating with a connection network to which a lost or disabled communication network was connected. The satellite antenna panel 100 can receive signals through a pointed satellite and transmit them to the connection network through the communication module 400.

In addition, the support member 210 may be made of carbon material to shield electromagnetic waves that cause malfunctions in the electronic compass 510, etc. and to reduce weight, but this is only an example and the material of the support member 210 is not used for the purpose. It may be formed differently as long as it does not deviate from the line.

As shown in FIG. 4, the rotating member 220 is a member coupled to rotate by the first axis servo motor 310 among the three servo motors 310, 320, and 330 forming the three axes, as shown in FIG. 5b.

The first to third axis servo motors 310, 320, and 330 as described above form a three-axis servo motor 300, and automatic precise pointing to the satellite may be possible through the rotation and angle adjustment structure as described above.

Meanwhile, the panel support 200 may further include an extension stand 250 and a panel housing 260.

The extension stand 250 may be formed to protrude more laterally than the support member 210 at a predetermined height at the lower end of the support member 210 . That is, the extension support 250 protrudes in a square shape based on the cubic support member 210.

It can be used as a cover to cover the panel 100 and protect it from the outside, and when the extension stand 250 is formed to be seated on the panel housing 260, the panel support 200 is placed on the panel housing 260, so the panel The housing 260 can be used as a base for the panel support 200.

When the panel housing 260 is used as a stand for the panel support 200, a certain space is provided between the panel support 200 and the panel housing 260, so goods, etc. can be stored between this space.

When used as a stand or as a stand, it can be used by binding the support member 210 and the panel housing 260.

In addition, the panel support 200 may be provided with a handle 280 on one side that can adjust the degree of protrusion, and on the other side, a rolling friction member that forms rolling friction on the panel support 200 when pulled by the handle 280 ( 285) can be provided.

Accordingly, the panel support 200 has excellent transportability and can be easily used in various places.

In addition, the panel housing 260 may be provided with a height variable member 287 at the upper end, as shown in FIG. 8, and the end of the height variable member 287 is positioned on the ground when seated on the ground. An elastic deformation member 289 that is elastically deformed may be provided.

For example, when the ground slopes downward toward the front, the height variable member 287 located in the front is set higher than the height variable member 287 located in the rear, so that the satellite antenna device can be maintained horizontal at the initial stage of installation. Through this, more precise pointing may be possible.

This height variable member 287 may be formed in the form of a rack-pinion, and the pinion is connected to a motor, etc., and the height variable member 287 is automatically operated by sensing or remote control of a sensor that measures the terrain to adjust the height. It can be adjusted.

However, the shape of the height-adjustable member 287 is illustrative, and is not necessarily limited thereto, and may be diversified as long as the height is adjustable.

In addition, as shown in FIG. 9, the panel support 200 supports the satellite antenna panel 100 through the above-described rotation member 220, angle adjustment member 230, and panel support member 240 between the support members 210. ) may be configured to further include a panel variable range expansion unit 290 that extends the variable range further.

It may be configured to be connected to (295).

The panel variable range expansion unit 290, which includes the above-mentioned components, operates the satellite antenna panel 100 through the piston action of each pressure cylinder (296, 297) and the rotational action of each link (291, 293). Pointing can be performed by expanding the variable range, and it can also be used to shift the center of gravity according to changes in terrain or surrounding environment.

Hereinafter, with reference to FIG. 10, the automatic satellite precise pointing method of the above-described satellite antenna device will be described in detail.

Figure 10 is a flowchart of the automatic satellite precise pointing method of the automatic precise pointing satellite antenna device according to an embodiment of the present invention.

Referring to FIG. 10, the satellite automatic precise pointing method of the satellite antenna device according to an embodiment of the present invention includes a first step (S10) of selecting a variable declaration satellite, an azimuth sensor (not shown), and an elevation sensor (not shown). and a second step (S20) of calculating the azimuth, elevation angle, and polar angle of the satellite antenna panel 100 through a polar angle sensor (not shown), displacing the calculated azimuth, elevation angle, and polar angle to match the selected variable declaration satellite. In the third step (S30), the sensor 520 generates adjustment displacements for azimuth, elevation, and polar angles, and if a satellite confirmation signal is generated, satellite signal confirmation is performed. If a satellite confirmation signal is not generated, satellite signal confirmation is performed. It may be configured to include a fourth step (S40) of readjusting the azimuth angle, elevation angle, and polar angle through precise adjustment of the 3-axis servo motor 300 until a confirmation signal of the satellite is generated.

Additionally, if the satellite signal is not confirmed in the fourth step (S40), a procedure to verify the presence or absence of an artificial magnetic field disturbance may be performed while performing precise adjustment of the 3-axis servo motor 300. If it is estimated that an artificial magnetic field has been generated when verifying the presence or absence of an artificial magnetic field disturbance, tracking using the electronic compass 510 is not easy, so only GPS 500 can be used or an own location tracking algorithm can be applied to track the satellite. It may be possible.

If automatic precise pointing of the satellite is performed as described above, the pointing stabilization time can be controlled within 240 seconds and the peak level for the satellite reception power can be controlled to 9.5V, resulting in a pointing stabilization time of 300 seconds, which is the level of a conventional device.
