Description

Technical Field

[0001] This invention relates to the field of satellite transponder technology, and in particular to a configuration method and apparatus for a high-throughput satellite transponder based on DTP. Background Technology

[0002] Compared with traditional communication satellites, high-throughput satellites have the following prominent features: First, they use higher frequency bands and frequency reuse technology to achieve greater available bandwidth, such as Ku and Ka bands; second, they use larger antennas to achieve high-gain multi-beams and improve system frequency utilization efficiency; third, they design larger platforms to carry more transponders and increase system capacity. As a result, the throughput of the next generation of high-throughput satellites will reach hundreds of gigabits per second or even terabits per second, and the number of beams will increase from dozens to hundreds.

[0003] With the increasing demand from emerging satellite communication markets such as airborne terminals, shipborne terminals, and high-speed rail terminals, and the uneven geographical distribution of the population, high-throughput satellite multi-beam systems face problems such as uneven distribution of user geographical locations and tidal effects in service time. Traditional high-throughput satellites with average and fixed beam resources suffer from uneven beam activity.

[0004] With the increasing application of flexible payloads, especially Digital Transparent Processors (DTPs), the design of DTP-based repeaters is of paramount importance. However, the current lack of relevant design and verification methodologies makes it impossible to provide technical feasibility verification for engineering applications. Summary of the Invention

If so, determine the number of flexible filters and the number of solid-state amplifiers based on the first transponder architecture; otherwise, determine the number of flexible filters and the number of traveling wave tube amplifiers based on the second transponder architecture.

[0013] S7. If the filter selection does not include a broadband filter, then the platform selection is performed according to the first repeater architecture or the second repeater architecture determined in step S6 to determine the target repeater architecture.

[0014] Furthermore, step S1 is followed by the following steps:

[0015] S8. If the filter selection does not include a flexible filter or the filter selection includes a broadband filter, then sort all beams from high to low according to the beam priority to generate a second set to be assigned.

[0016] S9. Select beams to be allocated sequentially from the second set of beams to be allocated in descending order of beam priority, and determine whether the sum of the maximum bandwidth of the beam to be allocated and the maximum bandwidth of each beam at port n does not exceed the bandwidth of the DTP port; where n is the DTP port number and n = 1; if yes, proceed to step S10.

[0017] S10. Assign the beam to be assigned to the port n, and remove the beam to be assigned from the second set of beams to be assigned; repeat steps S9 to S10 until all beams in the second set of beams to be assigned are selected.

[0018] S11. Determine whether the second set to be allocated is an empty set. If it is, determine that the number of DTP ports to be configured is n. Otherwise, increment n by 1 and repeat steps S9 to S11 until the second set to be allocated is an empty set.

[0019] S12. Determine the number of broadband filters and solid-state amplifiers based on the third transponder architecture, and select a platform to determine the target transponder architecture.

[0020] Furthermore, the first transponder architecture is a transponder architecture combining flexible filters and active beamforming, wherein the number of flexible filters is equal to the number of beams, and the number of solid-state amplifiers is equal to the number of beamforming network feeds; and / or

[0036] Figure 1 This invention illustrates a configuration method for a DTP-based high-throughput satellite transponder according to an embodiment of the present invention. The method is specifically applied to configuring a DTP transponder architecture that meets user requirements, and includes the following steps:

[0037] S1. Obtain configuration parameter information; the configuration parameter information includes at least the number of beams, beam bandwidth requirements, beam priority, DTP port bandwidth, filter selection, and amplifier selection. The configuration parameter information is set according to specific service requirements and can be input by the user according to specific service requirements, including the number of beams N, the bandwidth requirements of each beam at different times, beam priority, DTP port bandwidth B, filter selection, and amplifier selection, etc.

[0038] S2. If the filter selection includes flexible filters, then all beams are sorted from high to low according to the beam priority to generate a first set to be assigned. Specifically, after receiving the configuration parameter information in step S1, it is determined whether the filter selection in the configuration parameter information includes flexible filters. If it does, the process proceeds to step S2, whereby the beams are sorted from high to low priority according to the beam priority set in the configuration parameter information to form a first set to be assigned; that is, the first set to be assigned contains N beams at this time.

[0039] S3. Select beams to be assigned sequentially from the first set of beams to be assigned in descending order of beam priority, and determine whether the sum of the bandwidth of the beam to be assigned and the bandwidth of each beam at port n does not exceed the bandwidth of the DTP port at any time; where n is the DTP port number and n = 1; if so, proceed to step S4.

[0040] S4. Assign the beam to be assigned to port n and remove the beam to be assigned from the first set of beams to be assigned; repeat steps S3 to S4 until all beams in the first set of beams to be assigned are selected.

[0041] In practice, beams are selected sequentially from the first set of beams to be allocated according to their priority. It is then determined whether the sum of the bandwidth of the selected beam and the bandwidth of all beams currently at DTP port n does not exceed the DTP port bandwidth B at any given time. If so, the selected beam is allocated to DTP port n, and the beam is removed from the first set of beams to be allocated. Steps S3 and S4 are repeated until all beams in the first set of beams to be allocated are selected. Conversely, if the sum of the bandwidth of the selected beam and the bandwidth of all beams currently at DTP port n exceeds the DTP port bandwidth B at any given time, it is left unprocessed and retained in the first set of beams to be allocated. Then, another beam of the next priority order is selected to execute step S4, until all beams in the first set of beams to be allocated have been selected.

[0042] In this embodiment, the DTP port bandwidth B is greater than or equal to 2.5GHz.

[0043] S5. Determine if the first set to be allocated is empty. If so, determine the number of DTP ports to be configured as n. Otherwise, increment n by 1 and repeat steps S3 to S5 until the first set to be allocated is empty. If there are no beams in the first set to be allocated, then DTP port n can meet the needs of all beams, and the number of DTP ports is n. If there are still unallocated beams in the first set to be allocated, then set the DTP port number n = n + 1 and return to step S3 to repeat steps S3 to S5 until all beams in the first set to be allocated are allocated. Then proceed to step S6.

[0044] S6. Determine whether the amplifier selection is a solid-state amplifier. If so, determine the number of flexible filters and the number of solid-state amplifiers based on the first transponder architecture; otherwise, determine the number of flexible filters and the number of traveling wave tube amplifiers based on the second transponder architecture.

[0045] Specifically, the first transponder architecture is a transponder architecture combining flexible filters and active beamforming, where the number of flexible filters is equal to the number of beams, and the number of solid-state amplifiers is equal to the number of beamforming network feeds; the second transponder architecture is a transponder architecture combining flexible filters and passive beamforming, where the number of flexible filters is equal to the number of beams, and the number of traveling wave tube amplifiers is equal to the number of DTP ports.

[0046] In this embodiment, the amplifier selection in the configuration parameter information is determined to be a solid-state amplifier. If it is, a "flexible filter + active beamforming" transponder architecture is adopted, where the number of flexible filters is equal to the number of beams N, and the number of solid-state amplifiers is related to the beamforming network design, generally equal to the number of beamforming network feeds. Otherwise, a "flexible filter + passive beamforming" transponder architecture is adopted, where the number of flexible filters is equal to the number of beams N, and the number of traveling wave tube amplifiers is equal to the number of DTP ports n.

[0047] See Figure 3 The first transponder architecture employs flexible filters and solid-state amplifiers. After the feed link signal is frequency-converted into the DTP, the bandwidth is adjusted according to the beam-port correspondence and beam requirements, and the adjusted beam signal is output. After frequency conversion, it enters the multiplexer, where the flexible filters of each channel are adjusted according to the beam bandwidth. Then the beam enters the beamforming network, and after being amplified by the solid-state amplifier of each feed, it is transmitted to the ground by the antenna to provide services to users.

[0048] See Figure 4 The second transponder architecture employs flexible filters and traveling wave tube amplifiers. After the feed link signal is frequency-converted into the DTP, the bandwidth is adjusted according to the beam-port correspondence and beam requirements, and the adjusted beam signal is output. After frequency conversion, it enters the traveling wave tube amplifier, and then enters the multiplexer. The flexible filters of each channel are adjusted according to the beam bandwidth. Finally, the beam enters the beamforming network and is transmitted to the ground by the antenna to provide services to users.

[0049] After step S6, it is further determined whether the filter selection includes a broadband filter. If not, proceed to step S7.

[0050] S7. If the filter selection does not include a broadband filter, then the platform selection is performed according to the first or second repeater architecture determined in step S6 to determine the target repeater architecture.

[0051] In an optional implementation, step S1 is followed by the step:

[0052] S8. If the filter selection does not include a flexible filter or the filter selection includes a broadband filter, then sort all beams from high to low according to the beam priority to generate a second set to be assigned.

[0053] That is, after step S1, if it is determined that the filter selection in the configuration parameter information does not include a flexible filter, then proceed to step S8; or, after step S6, if it is determined that the filter selection includes a broadband filter, then also proceed to step S8; in step S8, all beams are sorted according to the order of beam priority to generate a second set to be assigned.

[0054] S9. Select beams to be assigned from the second set of beams to be assigned in descending order of beam priority, and determine whether the sum of the maximum bandwidth of the beam to be assigned and the maximum bandwidth of each beam at port n does not exceed the bandwidth of the DTP port; where n is the DTP port number and n = 1; if yes, proceed to step S10.

[0055] S10. Assign the beam to be assigned to port n and remove the beam to be assigned from the second set of beams to be assigned; repeat steps S9 to S10 until all beams in the second set of beams to be assigned are selected.

[0056] In practice, beams are selected sequentially from the second set of beams to be allocated, according to their priority. It is then determined whether the sum of the maximum bandwidth of the selected beam and the maximum bandwidth of all beams currently at DTP port n does not exceed the DTP port bandwidth B. If so, the selected beam is allocated to DTP port n and removed from the second set of beams to be allocated. Steps S9 to S10 are repeated until all beams in the second set of beams to be allocated are selected. Conversely, if the sum of the maximum bandwidth of the selected beam and the maximum bandwidth of all beams currently at DTP port n exceeds the DTP port bandwidth B, it is left unprocessed and retained in the second set of beams to be allocated. Another beam with the next priority is then selected to execute step S10, until all beams in the second set of beams to be allocated have been selected.

[0057] S11. Determine if the second set to be allocated is empty. If so, determine the number of DTP ports to be configured as n. Otherwise, increment n by 1 and repeat steps S9 to S11 until the second set to be allocated is empty. If there are no beams in the second set to be allocated, then DTP port n can meet the needs of all beams, and the number of DTP ports is n. If there are still unallocated beams in the second set to be allocated, then set the DTP port number n = n + 1 and return to step S9 to repeat steps S9 to S11 until all beams in the second set to be allocated are allocated. Then proceed to step S12.

[0058] S12. Determine the number of broadband filters and solid-state amplifiers based on the third transponder architecture, and select a platform to determine the target transponder architecture.

[0059] Specifically, the third transponder architecture is a transponder architecture combining broadband filters and active beamforming. The number of broadband filters is equal to the number of beams, and the number of solid-state amplifiers is equal to the number of beamforming network feeds. That is, the third transponder architecture in this embodiment adopts a "broadband filter + active beamforming" transponder architecture. The number of broadband filters is equal to the number of beams N, and the number of solid-state amplifiers is related to the beamforming network design, generally equal to the number of beamforming network feeds.

[0060] See Figure 5 The third transponder architecture uses a broadband filter and a solid-state amplifier. After the feed link signal is frequency-converted into the DTP, the bandwidth is adjusted according to the beam-port correspondence and beam requirements, and the adjusted beam signal is output. After frequency conversion, it enters the broadband filter, and then the beam enters the beamforming network. After being amplified by the solid-state amplifier of each feed, it is transmitted to the ground by the antenna to provide services to users.

[0061] Furthermore, the platform selection includes: if there are at least two repeater architectures, comparing specified parameters of each repeater architecture and determining the target repeater architecture based on the comparison results; wherein the specified parameters include weight, power consumption, heat dissipation, and matching platform capabilities. That is, when selecting a platform based on the repeater architecture, if multiple architecture options are available, the weight, power consumption, and heat dissipation of different options are compared, and the platform capabilities are matched to select the optimal repeater architecture option.

[0062] The specific steps of the DTP-based high-throughput satellite transponder configuration method provided in this embodiment are as follows: Figure 2 As shown, the method can be used not only to design various transponder architectures such as "flexible filter + active beamforming", "flexible filtering + passive beamforming", and "wideband filtering + active beamforming", but also to enable satellite communication systems to dynamically meet the beam bandwidth requirements at different times, thereby improving the system's on-orbit resource utilization. By jointly optimizing the number of individual units such as DTP ports, filters, and amplifiers, and combining the constraints of platform selection on the payload, the optimal transponder scheme can be selected.

[0063] On the other hand, based on the same inventive concept, the present invention also provides a configuration device for a DTP-based high-throughput satellite transponder, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the above-described configuration method for a DTP-based high-throughput satellite transponder.

[0064] In summary, the configuration method and device for a DTP-based high-throughput satellite transponder described in this invention, by acquiring configuration information and, based on the filter and amplifier selections within that information, allocates all beams to the corresponding DTP ports, determines the transponder architecture, and selects a platform to obtain the target transponder architecture. Thus, this invention can be applied to satellite transponder architecture design, and the resulting transponder architecture scheme enables the satellite communication system to dynamically meet the beam bandwidth requirements at different times, improving the system's on-orbit resource utilization.

[0065] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
