"Well only sort of" what? Yes, "GPS is the initialism for a specific system" and G is the initial for Global. The G in GNSS is also global so I am not sure how that is any different. The article is titled "Japan's Plan for Centimeter-Resolution GPS" and then goes on to describe a system that is anything but global.
- swatkat 13y agoGNSS is a generic term for globally available satellite navigation system. GPS is a GNSS implemented and maintained by the USA. Japan is planning to launch thier own satellites as part of QZSS program, to augment this GPS coverage over Japan. GPS receivers in Japan can make use of these "local" sats along with American sats for more accurate positioning.
