C & C Technologies, Inc. Marine Construction Department offers Surface Positioning with Real Time QA/QC services by using Differential GPS. Differential GPS is implemented by placing a GPS monitor receiver at a precisely known location. Instead of computing a navigation fix, the monitor determines the range error to every GPS satellite it can track. These ranging errors are then transmitted to local users where they are applied as corrections before computing the navigation result.

Our job as the surveyor, is to provide positioning and navigation by using our C-Nav® Receivers and C-Nav® Subscription Service.

C-Nav® Subscription Service

The C-Nav® RTG Network is a global system for the distribution of dynamic GPS Precise Point Positioning corrections, giving the user the ability to measure his position anywhere in the world with exceptional reliability and unprecedented accuracy of better than 10 cm (4 inches). Because the differential GPS corrections are broadcast via Inmarsat geostationary satellites, 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.
