GNSS Correction Sources

The high level of accuracy you need on a construction site cannot be done with GPS alone. GPS accuracy and integrity can be enhanced using RTK correction services. There are many forms of RTK correction sources and all provide you the information needed to improve GPS/GNSS performance and accuracy.

Your GNSS operation is only as good as your correction source, making it important to choose the right one. Trimble’s GNSS correction services allow you to do just this. Large sites may need a GNSS base station while small sites can opt for a virtual correction source.
