Introduction

Roger Shun Hong Tong is a prominent inventor based in Hong Kong, CN. He holds a total of 11 patents that showcase his contributions to the field of satellite communications. His work focuses on enhancing the efficiency and effectiveness of satellite payloads and communication methods.

Latest Patents

Among his latest patents is a groundbreaking design for a satellite payload that utilizes full downlink spectrum usage. This innovation describes satellite communication methods and payloads that enable effective use of carrier signals in the guard band region of a channelized band of spectrum. The design includes an on-board digital channelizer that implements a band edge power monitor to measure power spectral density. If the density exceeds a preset threshold, the system downscales the signal amplitude to prevent hardware damage. Additionally, the channelizer features a band edge gain adjustment filter that shapes the overall frequency response, ensuring a flattened response across adjacent channels, including the guard band region.

Another significant patent involves high throughput satellites (HTS) and methods for relaying data between low earth orbit (LEO) satellites and ground stations. This patent outlines a method of operating the HTS, which includes determining the estimated trajectory of an orbiting LEO satellite and assigning a plurality of spot beams with matching color reuse polarization. This innovative approach allows for efficient data transmission and enhances the capabilities of satellite communication.
