Abstract : Techniques were developed to compute gravitational acceleration from the in-flight measurements recorded by an airborne magnetic tape recorder. The reduced data were collected during approximately 340 flight lines. In addition to the recorder, the aircraft carried three gravity meters--LaCoste-Romberg, Askania-Graf, and Worden--and the peripheral instruments needed to complement the gravity measurements. Developments included techniques to smooth the output from each of the three gravity meters; to derive and apply corrections such as those for the Eotvos effect and the aircraft's horizontal and vertical acceleration; and to compute an accurate latitude and longitude for each gravitational acceleration. In addition, computer programs were developed to process the data recorded on either charts or magnetic tape. (Author)
