C-Nav Coverage Map

The C-Nav® Corrections Service is a global system for the distribution of dynamic DGNSS Precise Point Positioning corrections, giving the user the ability to position anywhere in the world with exceptional reliability and unprecedented accuracy of better than 10 cm (4 inches). The differential GNSS corrections are broadcast via Inmarsat geostationary satellites, thus the user needs no local reference stations or post-processing to get this exceptional accuracy. The worldwide coverage of the geostationary satellites delivers a consistent high level of accuracy virtually anywhere from 72 N to 72 S latitude.
