用於運營高通量衛星的方法及系統 Methods and Systems for Operating a High Throughput Satellite | 一種高通量衛星及運營高通量衛星的方法。衛星具有多種運營模式,並且根據頻譜填充率而在它們之間轉換。運營模式可包括改變顏色(頻譜)復用模式以增加或減少顏色的數量、使用波束內地理細分或預編碼下行鏈路信號。A high throughput satellite and a method of operating a high throughput satellite. The satellite has multiple modes of operation and transitions between them in response to the spectrum fill rate. Modes of operation may include altering color re-use patterns to increase or reduce number of colors, using intra-beam geographic sub-division, or precoding downlink signals. |

用於高通量衛星的上行干擾地理定位方法及系統 Uplink Interference Geolocation Method and System for High Throughput Satellite | 一種用於定位高通量衛星干擾源的地理定位方法和系統。該方法涉及確定受害點波束接收的干擾信號與相同衛星上的共色相鄰點波束之間的相對功率水平差。使用波束方向圖數據,成對波束的相對功率水平確定可能位置的等值線,其對應於由該對中的兩個波束接收的信號相對功率差。來自多對點波束等值線的交叉點指出干擾源的位置。A method and system for locating the source of an unwanted signal (whether malicious or unintentional) to a multi-beam high throughput satellite, which is more susceptible to uplink interference due to the involvement of two-way communication to household and mobile users, i.e. uploading and downloading at the same time. This method makes use of the relative power level differences between interference signals received by the victim spot beam and co-colored nearby spot beams on the same satellite. |

用於近地軌道衛星與端點之間中繼數據的高通量衛星 (High Throughput Satellites and Methods of Operating High Throughput Satellites for Relaying Data between Low Earth Orbit Satellites to Endpoints) | 一種高通量衛星和一種運營高通量衛星的方法,用於在近地軌道(LEO)衛星和目標地面站之間中繼數據,其中高通量衛星為點波束覆蓋區提供多個點波束。運營高通量衛星的方法包括:確定一個在軌LEO衛星的估計軌跡;分配具有相同極化的顏色復用的多個點波束;以及將多個所分配點波束的分配信息發送給所述高通量衛星,以使所述高通量衛星維持經由第一點波束和具有相同極化的顏色復用的一個或多個分配的後續點波束的星間鏈路。(A high throughput satellite (HTS) and a method of operating the HTS for relaying data between a low earth orbit (LEO) satellite and a target ground station, where the HTS provides spot beams for a spot beam coverage area. The method of operating the HTS includes: determining an estimated trajectory of an orbiting LEO satellite; assigning a plurality of assigned spot beams having a matching color re-use polarization; and transmitting assignments of the plurality of assigned spot beams to the high throughput satellite to cause the high throughput satellite to maintain the inter-satellite link via a first spot beam and one or more assigned subsequent spot beams having the matching color re-use polarization.)
