Manual of Geodetic Astronomy: Determination of Longitude, Latitude, and Azimuth, 1947

摘要

The purpose of this publication is to set forth the methods currently used by this Survey in its astronomical work in the field and to describe in some detail the office methods used in computing and processing the field records. Much of the material in a previous manual, Special Publication No. 14, Determination of Time, Longitude, Latitude and Azimuth, has become obsolete, or nearly so, by the improvement in astronomical instruments and equipment in recent years. This manual covers only those instruments now in use by the U.S. Coast and Geodetic Survey and does not include discussions of experimental work with newer instruments or estimates of the usefulness of such instruments. The material in this manual is the product of the accumulated experience in office and field of the members of the U. S. Coast and Geodetic Survey from its earliest days to the present.
