Atmospheric Drag Density Data from AD-A, AD-B, and AD-C
Entry ID: AD-ABC

[ Update this Record ]

Summary
Abstract: This experiment was designed to determine nonsystematic changes of upper
atmospheric density by conducting studies of the drag on a 3.6-m diameter,
low-density sphere caused by short-term variations in solar activity. Density
values near perigee were deduced from sequential observations of the spacecraft
position using optical (Baker-Nunn camera network) and radio/radar tracking
techniques. The ... View entire text
