[0033] Figure 1 FIG. 1 is a flow chart of a method for evaluating the quality of satellite-to-ground communication of a low-orbit communication satellite provided by an embodiment of the present disclosure. Figure 1 As shown in FIG. 1 , the specific process of the method for evaluating the quality of low-orbit communication satellite-to-ground communication includes:

[0034] S110: Receive a communication quality detection request sent by a user equipment, where the communication quality detection request includes: an area location preset by the user equipment.

[0035] The user device may be a smart phone, a PC (Personal Computer), a tablet computer, etc. with information interaction function.

[0036] The regional location preset by the user equipment is a specific location where the user needs to query the satellite communication quality. For example, the regional location preset by the user equipment can be the geographical location where the user is located, or another geographical location other than its geographical location where the user equipment wants to query the satellite communication quality.

[0037] For example, the geographical location of the user equipment is City A, and the regional location preset by the user equipment may be City A, or City B, where City B is another geographical location other than the geographical location (City A) where the satellite communication quality is to be queried.

[0038] S120. In response to the communication quality detection request, obtain ionospheric monitoring data of the observation station.

[0039] Among them, the observation station ionosphere monitoring data is used to describe multiple partitioned ionosphere monitoring data obtained after the target station monitors the ionization area. The target station is a data monitoring station that is closest to the regional location pre-set by the user equipment.

[0040] For example, target station a has multiple partitions: a1, a2, a3 and a4. When target station a performs ionospheric data monitoring, it will monitor the partitioned ionospheric monitoring data of its partitions a1, a2, a3 and a4. Then the ionospheric monitoring data of the observation station may include: the ionospheric monitoring data of partition a1, the ionospheric monitoring data of partition a2, the ionospheric monitoring data of partition a3 and the ionospheric monitoring data of partition a4.

[0041] In some embodiments, obtaining ionospheric monitoring data of an observation station includes:

[0042] Obtain a service data table; determine from the service data table a plurality of ionospheric data monitoring stations with ionospheric data monitoring capabilities, each ionospheric data monitoring station obtains a plurality of corresponding subarea ionospheric monitoring data after performing data monitoring on an ionized area; determine a target station from a plurality of ionospheric data monitoring stations based on a regional location preset by a user device; determine the ionospheric monitoring data of the observation station based on the plurality of subarea ionospheric monitoring data obtained after the target station performs data monitoring on the ionized area.

[0043] The service data table includes: multiple candidate stations. It should be noted that not every candidate station among the multiple candidate stations has the ionospheric data monitoring function, that is, among the multiple candidate stations, some may not have the ionospheric data monitoring function, while another may have the ionospheric data monitoring function.

[0044] Each candidate station included in the service data table corresponds to a monitoring identifier, which can be used to display whether the candidate station has the ionospheric data monitoring function. The display form of the monitoring identifier may include: numbers, colors, or a combination of numbers and letters. This embodiment does not specifically limit the display form of the monitoring identifier.

[0045] Determining multiple ionospheric data monitoring stations with ionospheric data monitoring capability from the service data table may include: obtaining a monitoring identifier of each candidate station in the service data table, matching the relationship between the monitoring identifier of each candidate station and a preset identifier, and determining that the candidate station corresponding to the monitoring identifier matching the preset identifier is an ionospheric data monitoring station. The preset identifier is an identifier of a station with ionospheric data monitoring capability.

[0046] Determining the ionosphere monitoring data of the observation station based on multiple partitioned ionosphere monitoring data obtained after the target station monitors the ionosphere area may include: determining that the multiple partitioned ionosphere monitoring data obtained after the target station monitors the ionosphere area is the ionosphere monitoring data of the observation station.

[0047] Therefore, by determining multiple ionospheric data monitoring stations with ionospheric data monitoring capabilities from the service data table and using this to determine the target station, the ionospheric monitoring data of the observation station can be effectively measured.

[0048] In some embodiments, based on a regional location preset by a user equipment, determining a target station from a plurality of ionospheric data monitoring stations includes:

[0049] A station search range is constructed with a regional position preset by the user equipment as the center and a preset length value as the radius; it is determined whether there is at least one ionospheric data monitoring station in the station search range; if there is an ionospheric data monitoring station in the station search range, an ionospheric data monitoring station is determined as a target station; if there are at least two ionospheric data monitoring stations in the station search range, an ionospheric data monitoring station that is closest to the regional position preset by the user equipment among the at least two ionospheric data monitoring stations is determined as the target station.

[0050] Among them, the preset length value can be 50km.

[0051] When determining whether there is at least one ionospheric data monitoring station in the station search range, a search signal can be sent to each position in the station search range. If an ionospheric data monitoring station responds to the search signal, it is determined that there is an ionospheric data monitoring station in the station search range.

[0052] If there are at least two ionospheric data monitoring stations in the station search range, determining an ionospheric data monitoring station of the at least two ionospheric data monitoring stations that is closest to the regional position preset by the user equipment as the target station may include: if there are at least two ionospheric data monitoring stations in the station search range, and at least two ionospheric data monitoring stations are the same as and closest to the regional position preset by the user equipment, determining any one of the at least two ionospheric data monitoring stations as the target station. Thus, the target station that is adapted to the regional position preset by the user equipment is effectively determined.

[0053] In some embodiments, it also includes:

[0054] If there is no ionospheric data monitoring station in the station search range, the preset length value is increased to expand the station search range; if there is an ionospheric data monitoring station in the station search range, an ionospheric data monitoring station is determined as the target station; if there are at least two ionospheric data monitoring stations in the station search range, an ionospheric data monitoring station that is closest to the regional position preset by the user equipment among the at least two ionospheric data monitoring stations is determined as the target station.

[0055] If there is no ionospheric data monitoring station in the station search range, the preset length value is increased. At this time, the preset length value can be increased from 50Km to 80km, the station search range is expanded to a radius of 80km, and the station search is performed again.

[0056] If there is an ionospheric data monitoring station in the station search range with a radius of 80km, then this ionospheric data monitoring station is determined as the target station; if there are at least two ionospheric data monitoring stations in the station search range, then the ionospheric data monitoring station that is closest to the regional position preset by the user equipment among the at least two ionospheric data monitoring stations is determined as the target station, so as to find out the effective target station by expanding the station search range and to evaluate the satellite communication quality.

[0057] In some embodiments, the method of this embodiment may further include:

[0058] If there is still no ionospheric data monitoring station in the station search range, an ionospheric data monitoring station closest to the regional position preset by the user equipment is determined as the target station from multiple ionospheric data monitoring stations with ionospheric data monitoring capabilities included in the service data table.

[0059] Based on the multiple sub-area ionosphere monitoring data obtained after the target station monitors the ionization area, the ionosphere monitoring data of the observation station is determined, including:

[0060] Obtain historical ionospheric monitoring data corresponding to the regional location preset by the user equipment; determine the ionospheric monitoring data of the observation station based on the historical ionospheric monitoring data corresponding to the regional location preset by the user equipment and multiple partitioned ionospheric monitoring data corresponding to the target station.

[0061] Among them, the historical ionospheric monitoring data corresponding to the regional location preset by the user equipment is the ionospheric monitoring data of the regional location corresponding to the user equipment during the historical monitoring process (such as within the previous day).

[0062] Determining the observation station ionosphere monitoring data based on historical ionosphere monitoring data corresponding to a regional location preset by a user device and a plurality of partitioned ionosphere monitoring data corresponding to a target station may include: performing data adjustment based on the historical ionosphere monitoring data corresponding to a regional location preset by the user device and using a plurality of partitioned ionosphere monitoring data corresponding to a target station to obtain the observation station ionosphere monitoring data.

[0063] When adjusting the data, the corresponding weight coefficient can be found from the preset parameter table according to the difference between the multiple partitioned ionosphere monitoring data corresponding to the target station and the historical ionosphere monitoring data corresponding to the regional position preset by the user equipment, and the multiple partitioned ionosphere monitoring data corresponding to the target station can be adjusted based on the corresponding weight coefficient to obtain the ionosphere monitoring data of the observation station.

[0064] S130. Determine the ionosphere monitoring data of the target area based on the ionosphere monitoring data of the observation station and the regional position preset by the user equipment.

[0065] The target area ionosphere monitoring data is a partitioned ionosphere monitoring data in the observation station ionosphere monitoring data that matches the regional position pre-set by the user equipment.

[0066] The ionospheric monitoring data of the observation station include: partitioned ionospheric amplitude scintillation index, partitioned ionospheric phase scintillation index and partitioned position (such as longitude, latitude). The difference between the partitioned position and the regional position preset by the user equipment can be used to determine a partitioned ionospheric monitoring number that matches the regional position preset by the user equipment, that is, the ionospheric monitoring data of the target area.

[0067] S140: Based on a preset evaluation coefficient, the ionosphere monitoring data of the target area is used to evaluate the low-orbit communication satellite-to-ground communication quality, and obtain the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment.

[0068] The preset evaluation coefficients include: communication stability evaluation coefficient, communication fluctuation evaluation coefficient and communication interruption evaluation coefficient. For example, the communication stability evaluation coefficient is 0.2, the communication fluctuation evaluation coefficient is 0.4, and the communication interruption evaluation coefficient is 0.6.

[0069] When the preset evaluation coefficient is used to evaluate the satellite-to-ground communication quality of a low-orbit communication satellite using the ionosphere monitoring data of the target area, the preset evaluation coefficient is used to evaluate the communication quality using the partitioned ionosphere amplitude scintillation index and / or the partitioned ionosphere phase scintillation index in the ionosphere monitoring data of the target area.

[0070] In some embodiments, based on a preset evaluation coefficient, the ionosphere monitoring data of the target area is used to evaluate the low-orbit communication satellite-to-ground communication quality, and the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is obtained, including:

[0071] If the ionosphere monitoring data of the target area is less than or equal to the communication stability evaluation coefficient, it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a first-level communication index.

[0072] For example, if the partitioned ionosphere amplitude scintillation index / partitioned ionosphere phase scintillation index in the target area ionosphere monitoring data is less than or equal to 0.2, or the average of the partitioned ionosphere amplitude scintillation index and the partitioned ionosphere phase scintillation index in the target area ionosphere monitoring data is less than or equal to 0.2, then it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a first-level communication index, which means that the low-orbit communication satellite-to-ground communication quality is good and is little affected by space weather changes.

[0073] If the ionosphere monitoring data of the target area is greater than the communication stability evaluation coefficient and is less than or equal to the communication floating evaluation coefficient, it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a secondary communication index.

[0074] For example, if the partitioned ionosphere amplitude scintillation index / partitioned ionosphere phase scintillation index in the target area ionosphere monitoring data is greater than 0.2 and less than or equal to 0.4, or the average of the partitioned ionosphere amplitude scintillation index and the partitioned ionosphere phase scintillation index in the target area ionosphere monitoring data is greater than 0.2 and less than or equal to 0.4, then it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a secondary communication index, which means that the low-orbit communication satellite-to-ground communication quality is slightly reduced and interference is caused by changes in space weather.

[0075] If the ionosphere monitoring data of the target area is greater than the communication floating evaluation coefficient and is less than or equal to the communication interruption evaluation coefficient, it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a third-level communication index.

[0076] For example, if the partitioned ionosphere amplitude scintillation index / partitioned ionosphere phase scintillation index in the target area ionosphere monitoring data is greater than 0.4 and less than or equal to 0.6, or the average of the partitioned ionosphere amplitude scintillation index and the partitioned ionosphere phase scintillation index in the target area ionosphere monitoring data is greater than 0.4 and less than or equal to 0.6, then it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a third-level communication index, which means that the low-orbit communication satellite-to-ground communication quality is slightly reduced, is greatly affected by space weather changes, has obvious signal amplitude attenuation, has a decreased carrier-to-noise ratio of the channel, and has increased bit error rate.

[0077] If the ionosphere monitoring data of the target area is greater than the communication interruption evaluation coefficient, it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a level 4 communication index.

[0078] For example, if the partitioned ionospheric amplitude scintillation index / partitioned ionospheric phase scintillation index in the target area ionosphere monitoring data is greater than 0.6, or the average of the partitioned ionosphere amplitude scintillation index and the partitioned ionosphere phase scintillation index in the target area ionosphere monitoring data is greater than 0.6, then it is determined that the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment is a level 4 communication index, which means that the low-orbit communication satellite-to-ground communication quality is extremely low, the channel carrier-to-noise ratio drops by more than the threshold value, and the satellite communication link is interrupted due to space weather changes.

[0079] Among them, the satellite-to-ground communication quality of low-orbit communication satellites with a first-level communication index is greater than that of low-orbit communication satellites with a second-level communication index, the satellite-to-ground communication quality of low-orbit communication satellites with a second-level communication index is greater than that of low-orbit communication satellites with a third-level communication index, and the satellite-to-ground communication quality of low-orbit communication satellites with a third-level communication index is greater than that of low-orbit communication satellites with a fourth-level communication index.

[0080] S150: Sending to the user equipment a low-orbit communication satellite-to-ground communication quality index at a regional location preset by the user equipment.

[0081] Wherein, when sending the low-orbit communication satellite ground communication quality index at the regional location preset by the user equipment to the user equipment, the sending method of the low-orbit communication satellite ground communication quality index includes but is not limited to: text message, broadcast, email, etc.

[0082] The method for evaluating the satellite-to-ground communication quality of a low-orbit communication satellite provided in an embodiment of the present application receives a communication quality detection request sent by a user device, wherein the communication quality detection request includes: a regional position preset by the user device; in response to the communication quality detection request, obtaining observation station ionosphere monitoring data, the observation station ionosphere monitoring data is used to describe a plurality of partitioned ionosphere monitoring data obtained after a target station performs data monitoring on an ionized region, the target station being a data monitoring station closest to a regional position preset by the user device; based on the observation station ionosphere monitoring data and the regional position preset by the user device, determining the target regional ionosphere monitoring data, the target regional ionosphere monitoring data being a partitioned ionosphere monitoring data in the observation station ionosphere monitoring data that matches the regional position preset by the user device; based on a preset evaluation coefficient, using the target regional ionosphere monitoring data to evaluate the satellite-to-ground communication quality of the low-orbit communication satellite, and obtaining a satellite-to-ground communication quality index of the low-orbit communication satellite at the regional position preset by the user device; and sending the satellite-to-ground communication quality index of the low-orbit communication satellite at the regional position preset by the user device to the user device. In this way, the ionospheric monitoring data obtained through monitoring can effectively reflect the source changes that affect the communication quality, realize accurate assessment of the satellite-to-ground communication quality of low-orbit communication satellites, and effectively provide users with satellite communication quality with strong reference, which is conducive to improving data transmission efficiency.

[0083] In some embodiments, the method of this embodiment may further include:

[0084] Based on the low-orbit communication satellite-to-ground communication quality index at the regional position preset by the user equipment, the effective duration of the satellite-to-ground communication is determined; and the effective duration of the satellite-to-ground communication corresponding to the low-orbit communication satellite-to-ground communication quality index is sent to the user equipment.

[0085] Among them, when determining the effective duration of satellite-to-ground communication, it can be determined based on a communication duration reference table, which records the correspondence between the satellite-to-ground communication quality index of different low-orbit communication satellites and the effective duration of satellite-to-ground communication.

[0086] Therefore, by evaluating the satellite-to-ground communication quality index of the low-orbit communication satellite at the regional location preset by the user equipment, the effective duration of the satellite-to-ground communication is determined, and the effective duration of the satellite-to-ground communication is sent to the user equipment, which is convenient for the user equipment to refer to the transmission of communication data and further improve the data transmission efficiency.
