Introduction

Jie Ding is an accomplished inventor based in Durham, NC, known for his significant contributions to positioning technology. With a total of two patents to his name, he has developed innovative methods that enhance the accuracy of positioning systems, particularly in the context of varying ionosphere delays.

Latest Patents

Jie Ding's latest patents include "Single-epoch pseudo-range positioning under varying ionosphere delays" and "Rapid determination of an unknown position." The first patent presents a positioning method that accounts for frequently changing ionosphere delays. This method involves including a function that represents environmental bias in the pseudo-range determination associated with signals received from various sources. It also jointly solves for parameters representing the position of the signal receiver and clock drift. The environmental bias may be modeled as an ionosphere delay, characterized by variations in longitude and latitude from the signal source.

The second patent, "Rapid determination of an unknown position," describes a system that utilizes an interface and a processor to quickly determine an unknown position. The interface receives carrier phase and code information from global navigation satellite system signals. The processor calculates an accurate position based on double-difference phase information and the most likely integer solution for carrier phase ambiguity.
