Resumen de Location matters
Marks talks about Europe's positioning system, Galileo. The signals that rain down from such systems do more than tell people's satnavs where they are. They provide location information to emergency services and logistics and transport industries, and to emerging sectors like driverless cars and precision farming. They also sync phone networks, bank transactions and power grids. In recent weeks, Galileo and India's equivalent, IRNSS, both saw mysterious, in-orbit failures of their critical atomic clocks. The European Space Agency isn't commenting on its probe into the clock failures as Galileo is "critical infrastructure."
