This suit was one of several concepts leading to the Manned Maneuvering Unit used with the Space Shuttle. The maneuvering apparatus was part of the suit assembly rather than a separate unit as in the MMU. The suit used a cold gas propulsion system which was fed through an umbilical line to the spacecraft.
