Station Report
Geoid velocity added
To correct for the vertical drift between reference frames, the velocity of the geoid height (VN) is now calculated and incorporated into the calculation of the orthometric height. View documentation to learn more.

Location
NRC1 is a continuously tracking GNSS station and is part of the Canadian Active Control System (CACS). The station is co-located with the NRC3 GNSS station at the Frequency and Time Laboratory, Institute for National Measurement Standards, National Research Council Canada in Ottawa, Ontario.
The station is located on the roof of a three storey building. The antenna is mounted on an extension of the steel structure of the building, anchored to bedrock and protruding through the roof.
