Title: Innovations of Inventor Hai Hu
Introduction
Hai Hu 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
One of Hai Hu's latest patents is for a satellite payload that utilizes full downlink spectrum usage. This innovation describes satellite communication methods and payloads designed to enable effective use of carrier signals in the guard band region of a channelized band of spectrum. The payload includes an on-board digital channelizer that implements a band edge power monitor to measure power spectral density in the band edges of a channel. If the measured 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 to flatten the response across adjacent channels, including the guard band region.
Another significant patent involves high throughput satellites (HTS) and methods for operating these satellites to relay data between low earth orbit (LEO) satellites and target ground stations. The HTS provides spot beams for coverage areas, and the method includes determining the estimated trajectory of an orbiting LEO satellite. It also involves assigning a plurality of spot beams with matching color reuse polarization and transmitting these assignments to maintain the inter-satellite link.
