Japan: A new technology developed by Mitsubishi and the Japan Aerospace Exploration Agency (JAXA) improves accuracy of GPS (which is approximately 10cm) to 3cm. This record for a non-military system was achieved during a recent public test in Japan, with a car driving at 20km/h.
JAXA and Mitsubishi claim former tests have shown their system maintains its accuracy with cars even driving up to 80km/h. The makers also say that because Michibiki satellite can cover Japan for just eight hours a day, two more satellites are needed to provide high-quality GPS for 24 hours.
Not too surprisingly, JAXA and Mitsubishi see the new tech used for future car navigation systems but also for advanced construction machines, child monitoring systems or travel guidance solutions, concludes a report published on crunchgear.com.
