The GPS function in smartphones makes getting around a breeze! Yet tall buildings can block signals and lower positioning accuracy. A new project has begun in Japan using a Quasi-Zenith Satellite. It uses a unique orbit that keeps it primarily above Japan. It also uses a signal that corrects positioning errors, making centimeter-level precision possible. Positioning technology is also being developed for places that satellite signals can't reach in preparation for the Olympics and Paralympics. |
