Latest Patents

The provided information lists 1 patent for Liu: “Satellite Signal Processing Method and Satellite Positioning Apparatus.” The invention describes an apparatus that uses an RNSS radio-frequency channel to receive signals and an RNSS baseband processor to calculate position, velocity, and time (PVT) information. Based on that information, an RDSS baseband processor determines a carrier-frequency offset and uses it to set the carrier frequency for receiving RDSS signals. The approach is intended to improve system performance and user experience when RNSS and RDSS technologies are integrated.

Career Highlights

Liu’s listed patent reflects work in satellite communications and positioning technology. The disclosed method connects RNSS-derived PVT information with RDSS signal reception, coordinating processing across the two satellite systems.
