Geodetic link between Canada and U.S.


  • Anonymous


A two-year program to complete a highly accurate geodetic survey linking Canada with Alaska and the lower 48 states was announced in July.

The U. S.—Canadian satellite triangulation program was initiated in 1964 using the balloon satellites Echo 1 and Echo 2 but was suspended in 1966 when the successful launching of the satellite PAGEOS signaled the start of the worldwide satellite program.
