Technical Session IV: Subsystems
Abstract
SURFER, the Stanford University Radio Frequency Emissions Receiver, is a small, free flying, spin stabilized satellite. It will take measurements of the earth’s ionosphere during the joint US/Italian Shuttle tether experiment. To obtain these measurements several sensors must be extended from the satellite to Specified positions. This will increase the resolution of the instruments and decrease the electromagnetic interference from the satellite electronics. The primary requirements for the deployment mechanism are: 1) The sensors must be positioned at least 60 inches from the satellite with ± 5% on the known deployed length and a ±1 degree tolerance on the known angular position. 2) Opposing sensors must be deployed simultaneously to within 10% of the total deployment time. 3) Full piece part redundancy is desired to eliminate single point failure.
