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
FRDN is a continuously tracking GNSS station and is part of the Canadian Active Control System (CACS). The station is located at the Hugh John Flemming Forestry Centre in Fredericton, New Brunswick.
The GNSS reference mark consists of a brass plate with a forced centered stainless steel bolt. The brass plate is cemented to the top of 12.0 m long steel casing, 0.1525 m in diameter. The 12.0 m steel casing is drilled 7.2 m into the ground and 3.0 m into bedrock and filled with concrete. The steel casing is 1.5 m above grade. The casing is inside a 0.900 m diameter plastic culvert extending from 5.8 m below grade to ground level and filled with gravel to a depth 1 meter below grade. A 0.600 m diameter concrete culvert is inserted into the plastic culvert and extends 1.5 m above grade.
