About C-Nav

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.

Redundancy 
C-Nav operates in a variety of redundant modes, incorporating redundancy through system and software diversity. In the unlikely event that the RTG signal subscription service fails, C-Nav will continue to deliver its inherent accuracy for some 20 minutes before reverting to fail-safe wide area augmentation solutions (e.g. WAAS or EGNOS) providing 1-2 meter accuracy.

Options and pricing
To select a high accuracy, quality controlled positioning solution that meets your needs, contact a C-Nav dealer in your region.

*At one sigma within adequate INMARSAT and GPS satellite visibility
