LOGACS 1, Agena



This spacecraft consisted of the Agena second stage, which was used to launch a classified primary payload. The Low-G Accelerometer Calibration System (LOGACS) experiment was the only one carried on the Agena. It was mounted on the aft of the vehicle, and included an accelerometer (MESA), a tape recorder, a clock, and telemetry equipment. The orbit lifetime was extended by additional firing of the rocket engines during orbit 18. Both real-time and tape-recorded data were obtained. Designed for a flight of low perigee because the altitude of experimental interest was in that region, the satellite had a short lifetime of only 8 days. More details of the spacecraft operation were in J. A. Pearson, "The Low-G Accelerometer Calibration System Orbital Accelerometer Experiment," vols. 1 and 2, 1973 (TRF B19604).
