What is a correction service provider?

The RD8200SG had been designed to provide survey grade GNSS accuracy.  In order to provide such accuracy, the common errors in current satellite navigation systems will need to be corrected.

To correct such errors, there are many 'correction service' providers available on the market and the availability will differ depending upon your requirements and the geographical area that you are operating in - Whilst some may be free of charge, others may be chargeable.

Some examples of international or regional correction services are listed below:

There are a number of free correction service providers available in the US.  Please use the link below.
