Abstract

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 (spectrum) re-use patterns to increase or reduce number of colors, using intra-beam geographic sub-division, or precoding downlink signals.

Description

technical field [0001] The present application relates to the field of satellite communications, and more particularly to methods and systems for operating high throughput satellites (HTS). Background technique [0002] Conventional fixed service satellite (FSS) systems use one or more wide beams to cover large geographic areas. However, modern satellite communications are moving from FSS to HTS, which employs a large number of spot beams and relies on color (i.e., spectral) multiplexing to improve the capacity (aka throughput) of each beam. HTS is attractive because it enables higher-capacity uplinks and downlinks, while modern satellite communications place more emphasis on two-way communications, uplink and downlink to user terminal equipment, such as satellite-based mobile Internet communication services. [0003] Color multiplexing is one way to reduce inter-beam interference, but using a large number of colors can result in less bandwidth being allocated to each spot ...
