The antenna main board 14 is connected to a ground satellite terminal through a data line. It will be appreciated that the number of transmit antennas may be adjusted based on the actual application.
As shown in fig. 3, the antenna main board 14 has a plurality of functional chips and sensors integrated thereon. Specifically, the device comprises a main control chip 141, a power amplification chip 142 (connected with a receiving array antenna 15) connected with the main control chip 141, five array antenna control chips 143 (respectively corresponding to and controlling five transmitting array antennas), a storage 144 and a sensor assembly.

The power amplification chip 142 is connected to the main control chip 141 through a coaxial line. The main control chip 141 is also connected with an antenna-terminal transceiver interface 149 for data interaction with a ground satellite terminal.
According to the experimental principle of the embodiment of the application, the transmitting antenna and the receiving antenna are separated, and the signal is collected through the signal reflecting surface 3, so that the anti-interference capability of the system is effectively improved. The different orientation designs of the multiple transmit array antennas ensure that there is always a proper antenna face for signal transmission during satellite motion. Meanwhile, the integrated multiple sensors can acquire the position and posture information of the antenna in real time, and guarantee is provided for beam control.
In a second aspect, the present application provides a satellite communication control method, which is applied to the satellite communication ground antenna device, referring to fig. 4, and includes the following steps:
s410, position data, orientation data, and tilt data of the antenna device are acquired.
Before step S410, initial installation and adjustment are performed, and the antenna assembly support bar is directed to the satellite constellation track intersection point nearest to the area by rotating the base and the angle adjustment assembly, so as to ensure that the adjustable direction of the angle adjustment assembly is parallel to the right south direction of the geography. Such initial adjustment may ensure that the antenna arrangement is in an optimal operating position, providing a basis for subsequent communications.
In this embodiment, the system obtains the position and posture information of the antenna device in all directions. The main control chip obtains longitude and latitude coordinates through the satellite positioning chip, and can determine the position data (antenna coordinates CPa) of the antenna device in a geocentric fixed coordinate system by combining altitude data obtained by the air pressure sensor. Meanwhile, orientation data are acquired through the geomagnetic sensor, and the gyroscope acquires inclination angle data so as to determine the spatial attitude of the antenna.
S420, determining antenna coordinates of the antenna device in a geocentric fixed coordinate system according to the position data, determining a pointing angle of the antenna device relative to a geographic direction according to the orientation data, and determining a vertical deviation angle of the antenna device relative to the ground according to the inclination data.
And S430, calculating the linear distance between each communication satellite and the antenna coordinate according to the antenna coordinate and the pre-stored satellite constellation data, and determining the communication satellite with the minimum linear distance as the target communication satellite.
The system reads pre-stored satellite constellation data from the storage, wherein the data comprise the spatial position information of the satellite in a geocentric earth fixed coordinate system and the motion rule thereof.
In this embodiment, the main control chip first traverses each satellite Sn in the pre-stored satellite constellation data, and calculates the spatial position (satellite coordinates CPn) of the current time. Then, a linear distance Ln from the antenna coordinate CPa to each satellite coordinate CPn is calculated, and the satellite number Ns and the corresponding distance Ln are stored in the matrix An. By analyzing the data in the matrix An, the satellite with the smallest Ln value is selected as the target communication satellite, and the number Nss and the position coordinate CPs thereof are obtained.
Furthermore, the antenna bracket of the application forms 45 degrees of layout of the antenna array and the longitude and latitude lines, and the arrays in 4 directions form 22.5 degrees of horizontal inclination angles with the central array, so that the antenna array optimally points to the satellite orbit at any time when the constellation design interval satellite forms an included angle of <45 degrees with the ground. When the constellation design interval satellite forms an included angle of <67.5 degrees with the ground, the antenna device can direct a transmitting beam to a communication antenna through beam forming.
S440, calculating elevation angle and rotation angle based on the antenna coordinates, the position of the target communication satellite and the origin of the geocentric-earth fixed coordinate system.
In this embodiment, the system calculates a rotation angle Roas and an elevation angle Eoas with the north pole axis of the earth as 0 point based on a triangle formed by the geocentric earth fixed coordinate system origin CPo, the antenna coordinate CPa and the communication satellite coordinate CPs.
And S450, compensating and calibrating the elevation angle and the rotation angle according to the pointing angle and the vertical deviation angle, and selecting the optimally pointed transmitting array antenna according to the calibrated elevation angle and rotation angle to transmit signals.
In this embodiment, the system acquires orientation data of the antenna device relative to the geographic north through the geomagnetic sensor, and acquires tilt angle data of the antenna device relative to the horizontal plane through the gyroscope. The orientation data is used to determine the actual pointing direction of the antenna in the horizontal plane, for example when the orientation data display device deviates from true north by 45 degrees, the system has to compensate for this deviation in calculating the rotation angle. The tilt data is used to correct for non-horizontal conditions of the antenna during installation or use, for example when the tilt data display device is tilted forward by 3 degrees, the system needs to subtract this tilt amount from the calculated elevation angle. The system uses the two attitude data as compensation parameters to correct the theoretically calculated elevation angle and rotation angle, so as to ensure the accuracy of beam pointing.
Specifically, in step S450, when the calibrated elevation angle is smaller than the preset deviation angle, the fifth transmitting array antenna is selected for signal transmission, and when the calibrated elevation angle is larger than the preset deviation angle, the transmitting array antenna with the optimal pointing direction is selected based on the calibrated rotation angle, referring to fig. 5, specifically:
S451, comparing the calibrated rotation angle with the axial angles of the first transmitting array antenna, the second transmitting array antenna, the third transmitting array antenna and the fourth transmitting array antenna respectively.
S452, calculating an included angle between the axial straight line of each transmitting array antenna and the connecting line of the target communication satellite, and selecting the transmitting array antenna with the smallest included angle as the transmitting array antenna with the optimal pointing direction.
S453, calculating the projection point of the target communication satellite on the optimally-directed transmitting array antenna plane, determining the projection rotation angle of the projection point relative to the coordinate reference axis, and transmitting the projection rotation angle and the included angle to the corresponding array antenna control chip for beam forming.
In this embodiment, the preset deviation angle is 11.25 °, and the first transmitting array antenna, the second transmitting array antenna, the third transmitting array antenna and the fourth transmitting array antenna are respectively directed to an upper space on the northeast side, an upper space on the southwest side and an upper space on the northwest side of the antenna transceiver assembly in the axial direction. When Eoas is smaller than 11.25 degrees, the system selects a fifth transmitting array antenna (central array antenna) for signal transmission. At this time, the main control chip transmits the calculated elevation angle (| Eoas |), rotation angle (| Roas) and data signal T to the array antenna control chip corresponding to the fifth transmitting array antenna, and the control chip performs beam forming processing to generate a transmitting signal and transmits the transmitting signal to the fifth transmitting array antenna for transmitting through the coaxial line. When the angle Eoas is larger than or equal to 11.25 degrees, the system selects the optimally-directed transmitting array antenna according to the rotation angle Roas. The specific process is that the angle Roas is compared with the axial angles of the four array antennas, the included angle between the axial straight line of each antenna and the connecting line of the target satellite is calculated, and the antenna with the smallest included angle is selected as the transmitting antenna. Then, the position of the satellite projection point on the selected antenna plane is calculated, the projection rotation angle of the projection point relative to the coordinate reference axis is determined, the corresponding elevation angle, rotation angle and data signals are transmitted to the corresponding control chip, and the control chip carries out beam forming processing and then transmits the signals. It will be appreciated that the predetermined offset angle may be other preferred angles.
Then, the power amplification chip receives a signal from a reception array antenna (sixth array antenna) through the coaxial line, and processes the received signal into a data signal. The signals are transmitted to the antenna main board through the data line, the main board further processes the data signals into data signals RX, and finally the data are transmitted to the ground satellite terminal through the antenna-terminal receiving and transmitting interface. Such a signal processing flow ensures the accuracy and reliability of the received signal.
Further, after determining the target communication satellite, the system not only selects a transmitting antenna with optimal pointing, but also calculates suboptimal pointing effects of other transmitting antennas on the target communication. When using the first transmit array antenna to communicate with a target communication satellite, the system will simultaneously prepare both antenna arrays if the second transmit array antenna is oriented at an angle to the satellite that is near optimum. When the pointing effect of the first transmitting array antenna is reduced due to satellite movement, the second transmitting array antenna is smoothly switched.
In calculating the linear distance between each communication satellite and the antenna coordinates, the system also calculates the relative distance change rate of each communication satellite and the antenna device. After selecting the communication satellite with the smallest linear distance as the target communication satellite, if the relative distance change rate is positive and greater than a preset threshold (for example, 200 m/s), the system selects the communication satellite with the second smallest relative distance and the negative distance change rate from the matrix An as the candidate satellite. The system calculates the elevation angle and rotation angle of the candidate satellite in advance and determines the optimally pointed transmitting array antenna. And when the elevation angle of the alternative satellite is more than or equal to 11.25 degrees, the optimal directional antennas in the first to fourth transmission array antennas are predetermined, and the corresponding projection point positions and projection rotation angles are calculated. The method ensures that parameter calculation and antenna preparation work of the alternative satellite are finished in advance while communication with the nearest satellite is maintained, lays a foundation for subsequent satellite switching, and ensures stable transition and stable operation of a communication system.
Specifically, the system establishes an antenna-satellite switching state table in memory for managing antenna combination states and satellite switching readiness states. The state table includes a current communication state, an antenna alternate state, and a satellite alternate state. The system updates parameters in the state table in real time, and when detecting that the pointing included angle of the currently used transmitting array antenna is about to exceed the optimal range, preferentially inquires the antenna alternative state and performs antenna switching, and when the antenna switching cannot meet the communication requirement, inquires the satellite alternative state and performs satellite switching.
Variations and modifications of the above embodiments will occur to those skilled in the art to which the application pertains from the foregoing disclosure and teachings. Therefore, the present application is not limited to the above-described embodiments, but is intended to be capable of modification, substitution or variation in light thereof, which will be apparent to those skilled in the art in light of the present teachings. In addition, although specific terms are used in the present specification, these terms are for convenience of description only and do not limit the present application in any way.
