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
SHEL is a continuously tracking GNSS site of the NSACS network. The GNSS station is located on an antenna mast at Shelburne Regional High School. 415 Woodlawn Dr, Shelburne, NS.
The GPS reference mark is a 5/8" threaded bolt at the top of an antenna mast made of structural steel. The steel mast (4.5 m) is attached to the cinder block, exterior wall of the school. The wall is attached to a concrete foundation. The geological characteristics are not known at the site. Reference mark changed to the threaded bolt at the top of the mast, located 0.0771 m below SECO thread bolt on 2014-02-21.
