1977 - Geodetic Astronomy in the Next Decade - AR Robbins
Pada era pertengahan 1970-an bidang astronomi geodetik mendapat tempat di kalangan para profesional ukur. Sebuah artikel tulisan AR Robbins terbit dalam jurnal Survey Review pada 1977. Artikel bertajuk "Geodetic astronomy in the next decade". Artikel tersebut pada asalnya dibentang kepada Royal Institute of Chartered Surveyors, London. Abstract artikel berkenaan: The paper discusses methods of determining azimuth and geoid height, recent tests of the possibility of using Doppler observations to artificial satellites to replace azimuth observations, and recent tests of inertial surveying equipment. It also discusses future instrumentation. It concludes that, for most purposes, Laplace azimuth observation may well soon be superseded by satellite observations but that astro-geodetic levelling will remain the most accurate method of interpolating geoid height for many years to come.
