Realtime Position Accuracy to Within 10 Centimeters

The Global Differential GPS (GDGPS) System is a real-time GNSS monitoring and augmentation system that provides location information to about 3-inch position accuracy. They use a large ground network of real-time reference receivers, innovative network architecture, and real-time data processing software, the GDGPS System provides sub-decimeter (less than 10 cm) positioning accuracy and sub-nanosecond time …

AI Enabled Fast Global Mapping as Surprise Most of the World is Still Not Mapped

Facebook, OpenStreetMap, and Map with AI are creating tools that will enable vastly faster mapping of unmapped roads and other unmapped feature. Artificial intelligence to predict features on high-resolution satellite imagery; these features are then populated in our RapiD map editing tool. When combined with global-scale humanitarian efforts, they hope RapiD can help realize our …
