C-Nav^® is a dynamic GPS Precise Point Positioning system, providing worldwide accuracy of <0.1 meter horizontally and 0.2 meter vertically.* C-Nav's superior solution is based on Real Time GYPSY^® technology developed by NASA's Jet Propulsion Laboratory to provide centimeter-level accuracy for navigation in space and for a range of complex spacecraft maneuvers.

A technological leap from DGPS
C-Nav does not suffer from the effects of spatial decorrelation found in traditional DGPS systems, nor does it require seeing common GPS satellites. It solves the problem by solving the cause of the problem - at its source. C-Nav's positioning is just as accurate in both marine and land environments. A single RTG subscription service, combined with C-Nav hardware, will provide worldwide positioning capability of 0.1 meter or better.
