ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,429,603, issued on Sept. 30, was assigned to u-blox AG (Thalwil, Switzerland).
"GNSS positioning based on changes in carrier range" was invented by Alex Parkins (Thalwil, Switzerland).
According to the abstract* released by the U.S. Patent & Trademark Office: "A GNSS receiver, a method of estimating position, and an associated computer program are provided. An example method includes calculating a first (full) position solution based on pseudorange measurements made at a first time. One or more position updates are then calculated based on the first position solution, using delta carrier range measurements which compare first carrier range measurements, made at the first time, with ...
