Caterpillar Company Logo   GNSS Correction Sources

CAT Machine Guidance GNSS Correction Sources

Your GNSS operations are only as good as your correction source. It’s important, so we let you choose the right one for you. Larger sites may need a GNSS base station, smaller sites may opt for a virtual correction source.


GPS alone does not give the high level of accuracy need on a construction site. The accuracy and integrity of GPS can be greatly enhanced by RTK correction services. RTK correction sources take many forms, but all provide information that improves GPS/GNSS performance and accuracy.


Choose the service that's right for you:

  • Trimble GNSS base station
  • Trimble Internet Base Station Service
  • Omnistar
  • Trimble VRS Now


For larger construction sites and those that include both site positioning and machine control operations, we recommend you deploy the Trimble SPS855 GNSS Modular Receiver as a permanent or semi-permanent base station.
