Appendix C C-Nav DGPS Correction Service
Description
The C-Nav Correction Service Network is a global
system for the distribution of SBAS corrections giving
the user the ability to measure their position anywhere
in the world with exceptional reliability and
unprecedented accuracy of better than 10cm (4 inches).
Because the corrections are broadcast via INMARSAT
geo-stationary satellites, the user needs no local
reference stations or post-processing to get this
exceptional accuracy. Furthermore, the same accuracy
is available virtually any where on the earth's surface on
land or sea from 76
°N to 76°S latitude, due to the
worldwide coverage of these geo-stationary satellites.
