Title: Yiran Luo and His GNSS Receiver Innovation.

Introduction

Yiran Luo is an inventor associated with Calgary, Canada. His patent work addresses satellite navigation in challenging conditions, particularly when GNSS signals are weak or changing dynamically. The available information lists 1 patent and identifies Uti Limited Partnership as his company.

Latest Patents

Luo’s listed patent, “Snapshot GNSS Receiver and Method Using Super-Long Coherent Integration and Fractional Fourier Transform,” describes a receiver designed to improve Doppler-rate estimation and positioning from weak, dynamic GNSS signals.

The receiver correlates incoming satellite signals and applies a Fractional Fourier Transform to the resulting outputs. This process estimates the Doppler rate, which is then used by a super-resolution-measurement module to calculate error values and a pseudorange through phase dead reckoning. A navigation module uses these inputs to determine position information. In some embodiments, the measurement module includes a maximum likelihood estimator.

Career Highlights

The patent reflects Luo’s work on signal processing and satellite-navigation technology. Its approach combines coherent integration, transform-based Doppler estimation, and pseudorange measurement to support positioning when signal conditions are difficult.
