The Low-G Accelerometer Calibration System Orbital Accelerometer Experiment. Volume II. Experiment Analyses and Results.

摘要

The LOGACS (Low-G Accelerometer Calibration System) experiment,which contained a miniature electrostatic accelerometer (MESA),was placed in a low-altitude polar orbit on 22May 1967. The experiment provided approximately 100hours of acceleration data from which the accelerometer scale factor,accelerometer null bias,and atmospheric drag on the satellite were calculated. Extensive comparisons of the data to verious model atmospheres are made. These analyses are the more interesting because of the intense solar and geomagnetic activity during the latter part of the LOGACS flight. From the data,both midlatitude and polar models of atmospheric density have been developed over altitudes for which LOGACS data were available. (Modified author abstract)
