A TIME-LAG GENERATOR FOR SPACECRAFT MAGNETIC DAMPING SYSTEMS.
Abstract
The circuit design of a subsystem used to approximate a time lag of several hours for use in spacecraft magnetic damping systems is discussed. Prior to the discussion of the electronics, a brief and very basic description is given of how the damping system operates and how the time-lag generator contributes to its operation. Two circuit designs are then discussed in detail. The first employs a simple sample-and-hold technique and was used in the DODGE satellite. The second, an extension of the first, uses an additional level of memory and might find application in similar satellites in the future. Some results of breadboard tests of both types of time-lag generator are included. (Author)
