Abstract:

The LOGACS Low-G Accelerometer Calibration System experiment, which contained a miniature electrostatic accelerometer Mesa, was placed in a low- altitude polar orbit on 22 May 1967. The experiment provided approximately 100 hours of acceleration data from which the accelerometer scale factor, accelerometer null bias, and atmospheric drag on the satellite were calculated. The mission description, the characteristics of the accelerometer, the instrumentation used in the experiment, and a summary of the results of the inflight accelerometer calibration are presented in this volume. The accelerometers sensing environment is discussed, as are the data reduction methods used to extract the scale factor and bias of the accelerometer and the methods of determining the acceleration due to aerodynamic drag.
