Background
To achieve global communication, since 1990, a number of low-earth satellite communication systems have been proposed, built and put into operation in succession. In a low-earth-orbit satellite communication system, a phased array antenna is widely applied to a low-earth-orbit communication satellite due to the characteristics of flexible beam pointing, rapid turning and the like.
Compared with a geosynchronous orbit communication satellite, the low-orbit communication satellite is different from the geosynchronous orbit communication satellite, the relative position relation between the geosynchronous orbit communication satellite and a ground target is fixed, namely, the service area of the satellite is fixed, and a beam control strategy is easy to realize. The relative position relationship between the low-earth orbit communication satellite and the ground fixed target changes constantly, and a low-earth orbit satellite communication system usually comprises hundreds or even thousands of satellites and tens of thousands of satellite beams, and the beam control is complex and frequent. Therefore, the number of the common satellite wave position numbering mode contains a small amount of information, and a wave beam control algorithm is complex.

Detailed Description
In order to more clearly illustrate the invention, the invention is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
As shown in fig. 1, a wave position numbering method:
the satellite is used as a center, the satellite service beam coverage angle is divided into a plurality of wave positions before being transmitted, the wave positions are fixedly connected with the satellite, and the ground service area covered by each wave position moves along with the movement of the satellite instead of the fixed service area on the earth. Each satellite can simultaneously generate 8 independent service beams, and a beam angle covered by the satellite is divided into 8 areas, wherein each area has a service beam freely pointing to the area;
as shown in fig. 2, the wave bits are arranged in rows along the flight direction of the satellite, and are divided into 8 regions according to the rows, and the wave bits in each region are equal;
as shown in fig. 3, the wave bit number is composed of 4-bit numbers, wherein the first bit number is a region number, and 8 regions are respectively represented by 1 to 8;
the first digit of the wave position number of the area closest to the center of the coverage area is represented by a number 1 and a number 2, the first digit of the wave position number of the area far away from the center of the coverage area is sequentially increased, the odd numbers of '1 area', '3 area', '5 area', '7 area' are positioned at the same side of the center of the coverage area, and the even numbers of '2 area', '4 area', '6 area', '8 area' are positioned at the other side of the center of the coverage area; the first area number of the wave position number is in one-to-one correspondence with the frequency point of the wave beam, so that the terminal and the satellite can acquire the wave position number and the frequency point of the wave beam at the same time.
The last three digits of the wave position number are the numbers in each area, the satellite flight positive direction digit number is in the front, and the satellite flight negative direction digit number is in the back; the number of the middle line in the area is in the front, and the number of the two side lines in the area is in the back; taking the '7 region' as an example, the first wave position in the flying positive direction in the central row of the region is selected and numbered as '7001' and '7002', the first wave position in the flying positive direction in the two side rows are numbered as '7003' and '7004', and the numbers at the back are sequentially arranged.
Merging the frequency information and the spatial information of the wave position into a wave position number;
calculating a binary wave control code corresponding to each wave position according to the fixed pointing relation between each wave position and the satellite; storing the wave position number and the corresponding binary wave control code in a wave control module, namely, a wave position list is built in the wave control module; a satellite acquires a wave position number to acquire frequency information and space information of the wave position; the satellite transmitting wave position number controls the wave beam of the phased array to point to the ground user.
And the terminal, the satellite and the ground station synchronously acquire the frequency information and the space information of the wave position when acquiring the wave position number. Not only simplifies the calculation process (without prejudging the satellite motion trail), but also reduces the interaction process of the terminal, the satellite and the ground station, thereby occupying less resources and improving the system efficiency.
The satellite user side has 8 independent control spot beams, the wave position area division is consistent with the spot beam service area, and the 8 beams respectively serve 8 areas. The wave position region shape is consistent with the flight direction of the satellite, so that the satellite can always use the same wave beam to serve users with the maximum probability when flying over fixed users and small-range mobile users, and further frequency point switching is not needed frequently.
After the satellite wave beams are numbered by the method, the wave position numbers not only contain the frequency point information of the wave positions, but also imply the information such as the space position information, the future service time and the like, so that the motion trail of the satellite does not need to be pre-judged in the wave beam control process, and the future service time of the terminal in the satellite can be obtained only according to the wave position numbers.
A method for selecting access satellite includes calculating wave position number of each satellite of user terminal when user terminal is covered by multiple satellite signals and satellite selection judgment is needed, comparing wave position numbers of different satellites and preferentially selecting satellite with smaller wave position number as access satellite.
