SDX-Cloud: Correction services - choose, check, and fix

A correction data service gives your Sodex system RTK accuracy. This page shows where to set it up, how to check that a project uses the one you expect, and which article helps when the positions or the status look wrong.

Set up a correction service

Each system in a project needs its own correction service. Start with Correction Data Service, or with RTK Premium Correction Data Service if you use the Sodex service. For UHF radio corrections, see SDX-Compact: UHF radio corrections.

Match the correction service to the project coordinates

The correction service, the localization file, and the project coordinate system must describe one reference. If scans, a design surface, and independent GPS checks differ by a constant offset, read SDX-Cloud: Scans are shifted by a constant offset. To choose and import coordinates, read Coordinate Systems and DC-File and LOK-File Import.

When the status or an import looks wrong

If the service is shown as not valid while it works in the field, read SDX-Cloud: A correction service shows as not valid but works on site. If a .lok file is refused, read SDX-Cloud: A .lok import fails with a Gauß-Krüger coordinate system.
