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
ALG2 is a continuously tracking GNSS station and is part of the Canadian Active Control System (CACS). The station is co-located with the ALGO GNSS station, the ALG3 GNSS station and the VLBI reference mark at the Algonquin Radio Observatory in Algonquin Park, 160km west of Ottawa, Ontario.
