On the sensor map, green indicates that the station is connected and in solution. Yellow indicates that we may have a connection, but that there may be an issue with data completeness, spotty comms, or data quality and that it does not presently meet standards for inclusion in the solution. Red means we have lost connection altogether for the time being. You will also see additional layers (see key below) that we have added to indicate things such as coverage areas, NGS National CORS, single base, network CORS, network geometry and locations planned for future CORS to be deployed.

Orange Dots - CORS in Network Solutions
Purple Dots - CORS Providing Single Base Solutions
Purple Rings - Single Base Coverage Area
Light Blue Ring - Network Coverage Area
Dark Blue Rings - NGS Adopted CORS in the NCN
Grey Lines - RTN Geometry (smaller polygons = more robust coverage)
Teal Plus Signs - Area targeted for future CORS deployment to shrink polygons
