Real-time corrections are available from VECTOR under the following conditions:

• Connections from field receiver to network must be made through the Internet.
• User authentication will make use of NTRIP (Network Transport of RTCM via Internet Protocol): A secure login (Username, Password) is required.  Users must “register” to use this service by filling out and submitting the registration form.
• Field receiver must have NTRIP communication ability.
• Data streams are in RTCM version 2.3 and 3.1 formats.

RTK correction data is obtained by connecting to a specific IP address, port, and mountpoint.  Note that the mountpoint is case sensitive.  For instance, if one were to request corrections from station Bradford, the connection string would be 170.222.32.141:2101/VTOX_CMR_Plus.  However, if users input simply the IP address and port, the user should be presented with the “SourceTable” which is the list of available mountpoints.  The user can then just select the mount point from the list.

 All connections are made through 170.222.32.141 port 2101.
