摘要:
Radio time‐signals are used by the Coast and Geodetic Survey in carrying on the field‐operations in (1) longitude‐determination, (2) gravity‐determination, and (3) azimuth‐measurement. A brief description will be given of the present methods employed on these phases of the geodetic operations and the, advantages which would be realized from more frequent signal‐broadcasts wil
