Yes, there are emerging technologies like improved satellite systems (e.g., Galileo and BeiDou), advanced positioning techniques (e.g., multi-sensor fusion), and increased use of machine learning algorithms that aim to enhance absolute location determination accuracy and reliability. ...
Some early electronic equipment like LORAN, Decca, RDF (radio direction finding) are no longer in the market since GPS has been available to the public. The electronic position-fixing system on board ships nowadays is normally shipborne GPS equipment or the developing BeiDou Navigation Satellite ...
“I don’t know of any cases [of GPS spoofing] that actually caused a plane to go down or a ship to run aground,” says Harrison Van Riper, strategy and research analyst at London-based Digital Shadows. “I don’t want to downplay the actual risk, but it’s not a widespread...
