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.
