Jesus Zamora

Title: Jesus Zamora and GNSS Positioning Innovation.

Introduction

Jesus Zamora is an inventor based in Zurich, Switzerland, and works at u-blox AG. His patent work addresses a challenge in global navigation satellite system (GNSS) positioning: mitigating multipath interference that can reduce positioning accuracy.

Latest Patents

Zamora’s listed patent, “GNSS positioning,” describes a method that compares signal measurements from multiple space vehicles transmitting L5 and L1 and/or L2 signals. The method calculates pseudo-ranges and residuals for each signal, then evaluates a statistic based on the differences between the residuals for the L1 and/or L2 signals and those for the L5 signals.

When the statistic exceeds a predetermined threshold, the method determines the position using a subset of signals that includes L5 signals while excluding at least some L1 and/or L2 signals. Otherwise, it calculates the position using both the L5 and L1 and/or L2 signals. This approach is designed to reduce the influence of multipath interference on GNSS positioning. Zamora is associated with 1 patent.

Career Highlights

Zamora’s listed invention reflects work in satellite navigation and signal processing. By using comparisons among signals in different frequency bands to guide which measurements contribute to a position estimate, the method offers a way to adapt positioning calculations to potential interference.
