Develop a combination of easily accessible and cost efficient hard and software to allow community based precision geolocation. Compared to existing projects, we emphasize on creating a public networked service rather than an individual setup. We consider the project successful if we aggregate an equivalent or better service than existing NTRIP providers. While processing GNSS data, the related time information shall be made available in the form of public NTP servers.


The project shall be valuable for the public at large serving diverse purposes. Improving the location precision for mobile phones, vehicles, farmers machinery, drone pilots or other location and navigation purposes.
