Description

Mechanical Starlink Satellite Receiving Antenna

The new invention relates to a Starlink satellite receiving antenna, in particular, a device with a single mechanism receiving antenna that can replace the traditional VSTA using two independent antennas and the phased array electronic antenna of the Starlink system.

With the advancement of low earth orbit (LEO) satellite technology, the use of low earth orbit satellites to provide communication services has become more and more widespread. However, low-orbit satellites (LEO) are different from traditional artificial satellites. Most artificial satellites are synchronous satellites and work in GSO (Geosynchronous Orbit). This is because the rotation angular velocity of satellites in this orbit is synchronous with the earth, so it is called synchronous track. In synchronous orbit, the satellite is stationary relative to the earth, so it is relatively easy to adjust the ephemeris and align the ground communication stations. The disadvantage is that the distance is long and the power required for communication is high. Therefore, a heavy-duty antenna with large transmitting and receiving power and volume is required. equipment.

所示)，第接收天線80a此時也回到B點位置(如圖中實虛線

所示)，依此類推，二個接收天線80a、80b不斷的換手。是以，INTELLIAN的VSAT必須使用二個獨立的接收天線80a、80b，因此不僅成本增加，且二個獨立的接收天線不斷換手在操作上較複雜，為其缺失。此類型專利另揭露於US20210399416A1、US20190157765A1等專利案中。 Figure 1A shows a conventional low-orbit satellite receiving antenna 80 disclosed by INTELLIAN TECHNOLGIES, Inc., which belongs to a Very Small Aperture Terminal (VSAT). This type of patent is disclosed in US 2021/0066778A1 patent, the receiving antenna 80 includes an elevation angle (Elevation angle) adjustment device 81, an oblique angle (Oblique angle) adjustment device 82, and an azimuth angle (Azimuth angle) adjustment device 83; as shown in Figure 1B, since the low-orbit satellite is running on the orbit The speed is very fast. Therefore, the User Equipment (UE) on the surface needs to frequently change hands to a new target satellite (target satellite), which means that there need to be at least two receiving antennas 80a and 80b. , when the first receiving antenna 80a and the second receiving antenna 80b track the first satellite S1 counterclockwise from point B to point c (solid line in the figure)

, dashed line

as shown), when the second satellite S2 is approaching point A, the second receiving antenna 80b first returns to point a to track the second satellite S2 (solid line in the figure)

as shown), and when the second satellite S2 comes to the position of point b, in addition to the second receiving antenna 80b continuing to track (the solid dotted line in the figure

as shown), the receiving antenna 80a also returns to the position of point B at this time (the solid and dotted line in the figure

shown), and so on, the two receiving antennas 80a and 80b constantly change hands. Therefore, INTELLIAN's VSAT must use two independent receiving antennas 80a and 80b. Therefore, not only the cost increases, but also the operational complexity of two independent receiving antennas constantly changing hands is a disadvantage. This type of patent is also disclosed in patent cases such as US20210399416A1 and US20190157765A1.

In addition, among the technologies related to low-orbit satellites, the antenna 90 used by SpaceX's Starlink system is shown in Figure 2. When the Starlink client antenna communicates, it does not connect to a single satellite, but flies along the entire satellite. Orbit, therefore, must be achieved using a phased array antenna board 91 instead of the traditional directional satellite antenna 80 as shown in Figure 1. This is because the phased array antenna board 91 supports beamforming, which is easier Aim at the satellites gliding across the sky. The phased array antenna board 91 has a motor device 92 on the back. In addition, the Starlink antenna 90 also includes a power supply 93 and a router 94 .

Phased array technology uses multiple antenna units to control the radiation pattern or beam by changing the relative phase of each unit, and uses microwave transmission lines and power divider systems to connect the antenna units. In the phased array antenna 90 design, interference or "beamforming" between two or more radiated signals is used to control the direction of the transmit beam. The antenna board 91 implements beamforming by adjusting the phase difference between the drive signals sent to each transmitter in the array. SpaceX's US PATENT announcement No. 20180241122 disclosed the working mechanism of some phased array antennas. The antennas have a motor and have automatic mechanical adjustment capabilities. It should be noted that this motor adjustment only has the mechanical adjustment capability in one direction. It is basically certain that this motor adjustment is only used to adjust the pitch angle. The terminal can automatically adjust the pitch angle according to its longitude and latitude geographical location, and adopts phase control. The array realizes automatic tracking of sent and received signals.

According to Wei Cha, the antenna used by the Starlink system for star finding and tracking usually uses an electronically scanned array radar (electronically scanned array). However, the cost of using an electronically scanned array radar is very high, and the failure rate is also high. Therefore, how to reduce antenna costs and failure rates has become an urgent problem to be solved.

The company has decades of experience in manufacturing synchronous satellite receiving antennas, so it is actively researching and developing how to use traditional satellite receiving antennas to solve the above problems of Starlink system antennas.

The main purpose of this new model is to provide a mechanical Starlink satellite receiving antenna, which uses two dish antennas on a single receiving device to cross and swing in opposite directions to form a "mechanical type" that can be quickly switched to a new target satellite.

The following description takes the accompanying drawings as embodiments, but is not limited thereto. The present invention can still be implemented in other embodiments, and the well-known steps or components are not described in detail to avoid ambiguity of the present invention. The shape creates unnecessary restrictions. Please note that the drawings are for schematic purposes only and do not represent the actual size or quantity of components. Some details may not be fully drawn for the sake of simplicity.

First, please refer to Figures 3 to 10. A preferred and feasible embodiment of the new "mechanical starlink satellite receiving antenna" 70A includes: a base 10 with an upright central axis 11 (see Figure 6C). (Z-axis); a horizontal axis adjustment device 20 is installed on the base 10. Please cooperate with it as shown in Figure 4 and Figure 6C. It includes: a slewing base 21, the bottom of which is connected to a first pulley 22, and is provided with On the central shaft 11; a first motor 23 is arranged on the rotary base 21, and a second pulley 24 is connected to its rotating shaft 231. The second pulley 24 drives the first motor 23 through a first transmission belt 25. The pulley 22, in turn, can link the slewing base 21 to rotate clockwise or counterclockwise on the central axis 11; in this embodiment, the slewing base 21 is in the form of a long plate, but it is not limited to this, and it can be in a shape of a long plate. The first motor 23 is used to drive the rotation, so that the dish antenna 30 on the rotary base 21 can be adjusted on the horizontal axis (indicated by A in the figure), which can also be said to be an adjustment mechanism. The azimuth angle (θ) of the Starlink satellite receiving antenna 70A is adjusted to 7B in Figure 7A, which is the first necessary means of this new type.

As shown in Figure 3, a set of dish antennas 30, consisting of a first dish antenna 30a and a second dish antenna 30b, are arranged inversely symmetrically on the left and right sides above the horizontal axis adjustment device 20. , which are driven by a first arm 31a and a second arm 31b respectively, and can exhibit synchronous reverse cross swings; in this embodiment, the first dish antenna 30a and the second dish antenna 30b are circular, However, it is not limited to this; as shown in FIG. 9 , the dish antenna 30 may include: rectangular shapes 33a and 300b, or other elliptical shapes. Furthermore, the first dish antenna 30a and the second dish antenna 30b further include waveguides 32a, 32b and other electronic equipment 33a for receiving Starlink satellite signals; for example: feeders, low noise Amplifier (LNA) or downconverter, etc., but these electronic equipment 33a belong to the prior art (Prior Art) and are not the subject of the patent of the present model and will not be described in detail.

As shown in Figures 3 and 4 and Figures 5A and 5B, a Starlink satellite orbit adjustment device 40 is installed on the slewing base 21 and includes: a transverse axis 41, with a first first axis being set at both ends of the transverse axis 41. Helical gear 42 and a second helical gear 43. The first helical gear 42 and the second helical gear 43 have the same size, and their two helical tooth portions 421 and 431 are arranged oppositely and can rotate on the transverse axis 41. , and its two sleeve parts 422 and 432 are respectively connected to the bottom ends of the first arm 31a and the second arm 31b, and can drive the first arm 31a and the second arm 31b to swing on the transverse axis 41; a first The three helical gears 44 are vertical and meshed with the first helical gear 42 and the second helical gear 43. They are driven by the rotating shaft 451 of a second motor 45 and can rotate forward or reversely. When the third helical gear 44 is rotated forward or reversely, When the gear 44 rotates forward or reverse, it drives the first helical gear 42 and the second helical gear 43 to rotate synchronously and reversely on the transverse axis 41 (X-axis), thereby driving the first arm 31a and the second helical gear 43. The arm 31b swings crosswise in the opposite direction on the transverse axis 41 for handover tracking of Starlink satellites in low orbit.

In this embodiment, the first helical gear 42 and the second helical gear 43 are not fixed on the transverse shaft 41, and the second motor 45 drives the third helical gear 44 to rotate forward or reverse, and then synchronize The first helical gear 42 and the second helical gear 43 are driven, as well as the first arm 31a and the second arm 31b, to cross-swing in the opposite direction on the transverse axis 41, as shown in Figures 6A and 6B; Figure 6A shows The first dish antenna 30a (Z1 axis) is aligned with the satellites in the Starlink satellite orbit B. Figure 6B shows that the second dish antenna 30b (Z2 axis) is aligned with the satellites in the Starlink satellite orbit B. In this way, the directivities of the first dish antenna 30a and the second dish antenna 30b driven by the first arm 31a and the second arm 31b continuously cross between the Z1-Z2 axes, and the star can be aligned. This is the second necessary means of this new type of tracking of satellites in chain satellite orbits (referred to as B in the figure).

As shown in Figure 4 and Figures 5A and 5B, an elevation adjustment device 50 is provided on the slewing base 21 and includes: a third motor 51, which is provided on the corresponding surface (Y-axis) of the second motor 45, The rotation axis 52 is vertical and connected to the transverse axis 41, and is used to drive the transverse axis 41 and the first arm 31a and the second arm 31b at both ends to swing left and right with the rotation axis 52 as the center. To adjust the elevation angle of the first dish antenna 30a and the second dish antenna 30b (indicated by C in the figure), the new elevation adjustment device 50 is cleverly located on the corresponding surface of the second motor 45. When it drives the horizontal When the shaft 41 and the first arm 31a and the second arm 31b at both ends swing left and right with the rotation axis 52 as the center, the first helical gear 42 and the second helical gear 43 will be driven by the transverse axis 41 It swings left and right, but it still remains in mesh with the third helical gear 44 when swinging left and right, which does not affect the operation of the Starlink satellite orbit adjustment device 40 at all. The "elevation angle adjustment" here can also be said to be Left and right tilt angle adjustment, for example: adjust to X1-X1 tilt angle or adjust to X2-X2 tilt angle. Furthermore, the Starlink satellite orbit adjustment device 40 and the elevation angle adjustment device 50 are cleverly combined on the slewing base 21, making the overall space configuration and operation very smooth. This is the third necessary means of the present invention.

As shown in Figures 8A, 8B and 8C, a set of polarization adjustment devices 60 is composed of a first polarization adjustment device 60A and a second polarization adjustment device 60B, which are respectively provided on the first arm 31a and the second polarization adjustment device 60B. Above the two arms 31b, the first polarization adjustment device 60A includes: a support base 61, which is a hollow body and the inner end is fixed on the upper end of the first arm 31a; a fourth motor 62 is located on the support base 61, its rotating shaft 621 extends into the support seat 61 and is connected to a third pulley 63. The third pulley 63 drives a fourth pulley 64 through a second transmission belt 65. The fourth pulley 64 can be in An axis 66 rotates, and its upper end 641 protrudes above the support base 61, thereby linking the deflection of the first dish antenna 30a. In addition, the second polarization adjustment device 60B is located above the second arm 31b. It has the same structure as the first polarization adjustment device 60A and is used to drive the second dish antenna 30b to deflect, so its structure will not be described again. . The so-called "polarization of the antenna" refers to the direction of the electric field intensity formed when the antenna radiates. Since directional antennas have the maximum radiation or reception direction, they have relatively strong anti-interference ability, so they need to be optimally adjusted; as for the principle of antenna polarization: There is no need to go into details about the previous technology. In the present invention, the polarization adjusting device 60 can be used to adjust the polarization directions (indicated by D in the figure) of the first dish antenna 30a and the second dish antenna 30b, which is the fourth necessary means of the present invention.

This new model combines the above four technical means to form a mechanical Starlink satellite receiving antenna 70A, which can control the first dish antenna 30a and the second dish antenna 30b to track the Starlink satellite orbit and adjust the level at the same time. axis, elevation angle and polarization direction to achieve fast and accurate reception of Starlink satellite signals. Of course, as shown in Figure 9, a mechanical Starlink satellite receiving antenna 70B composed of two rectangular dish antennas 300a and 300b can also achieve the same purpose and effect.

Please refer to the control schematic diagram of the new antenna control device shown in Figure 10. The new antenna control device 100 can receive ephemeris information from satellites S1 and S2, and can control the mechanism star chain based on the ephemeris information. Satellite receiving antenna 70A. The ephemeris information may include information such as the azimuth angle and elevation angle of satellites S1 and S2. In addition, although the antenna control device 100 and the mechanical Starlink satellite receiving antenna 70A are illustrated separately, the antenna control device 100 may be embodied in the antenna 70A as needed.

In this embodiment, the antenna control device 100 may include a receiver 101 and a controller 102. The receiver 101 may receive ephemeris information of satellites S1 and S2, and may also include a memory 103. The ephemeris information may to be stored in the memory 103 in advance. The ephemeris information may include information about the orbits on which the satellites S1 and S2 move hour by hour, and the receiver 101 may output the received ephemeris information to the controller 102 . In addition, the receiver 101 can store the received ephemeris information in the memory 103. The controller 102 can include a single processor or multiple processors, and it can use the processor to process the ephemeris information to control the mechanism. Starlink satellite receiving antenna. However, the antenna control device 100 and the reception of ephemeris information are prior art and are not the subject of the patent of the present invention, so they will not be described in detail.

The present invention mainly uses the controller 102 to process the data received by the receiver 101 and the data stored in the memory 103, and then the controller 102 can generate a control signal for controlling the mechanical Starlink satellite receiving antenna 70A. That is, the controller 102 can control the rotation of the first motor 23, the second motor 45, the third motor 51, and the fourth motor 62 respectively to adjust the elevation angle and tilt angle of the mechanical Starlink satellite receiving antenna 70A. (Oblique angle), azimuth angle (Azimuth angle) and polarization position, etc. Among them, the important feature is that by controlling the forward or reverse rotation of the second motor 45, the first dish antenna 30a and the second dish antenna 30b can be synchronously controlled to have an inversely symmetrical cross swing, and the stars can be tracked by changing hands. Satellites S1, S2... in chain satellite orbit B, and can adjust the horizontal axis, elevation angle and polarization direction at the same time to achieve fast and accurate reception of Starlink satellite signals.

In this way, this new type uses two dish antennas on a receiving device to cross and swing in opposite directions to form a "mechanical" receiving antenna that can quickly change hands to a new target satellite. It can replace the two currently used by traditional VSTA. Independent antennas and the "phased array" electronic antenna of the Starlink system can reduce costs and failure rates, thereby increasing the popularity and stability of Starlink satellite antennas.

To sum up, the technical means disclosed in this new model indeed meet the requirements for new patents such as "novelty", "progressivity" and "available for industrial utilization". We pray that the Jun Bureau will grant patents to encourage new types and without any restrictions. Sense of morality.
