Title: Johan Carlström and Underwater Positioning Innovation.

Introduction

Johan Carlström is an inventor associated with Linköping, Sweden, and Saab AB. His patent work addresses position-deviation estimation for nodes in underwater positioning systems.

Latest Patents

Carlström is associated with 1 patent: “Method for Determining a Position Deviation, a Positioning System and an Underwater Vehicle.” The method uses input data that includes an estimated position and velocity vector for a first node, along with the exact position of a second node. It also uses the emitted and observed frequencies of an acoustic signal to calculate relative velocity and the angle between velocity vectors. From these values, the method determines directional lines and estimates the second node’s position. It then compares that estimate with the second node’s exact position to calculate a deviation vector and determine the first node’s position deviation. The disclosure also describes a positioning system and an underwater vehicle.

Career Highlights

Carlström’s patent connects acoustic-signal measurements with position estimation and error correction. Its approach is intended to help determine positional deviations in underwater navigation contexts.
