Germany’s Bosch and Geo++u-blox of Switzerland, and Japan’s Mitsubishi Electric announced the establishment of Sapcorda Services, a joint-venture that plans to provide global navigation satellite system (GNSS) positioning services of centimeter-level accuracy via satellite transmission, mobile cellular technology, and the Internet.
The U.S.-operated Global Positioning System (GPS) is only accurate to about 10 meters, while Europe’s corresponding Galileo system now has an accuracy of 1 meter.

Details at the Sapcorda announcement were sketchy, but essentially it plans to augment GPS and Galileo positioning data in Europe by employing surveyed reference stations on the ground.
