IABS
 IABS stage with DSCS-3 satellite |
The IABS (Integrated Apogee Boost System) was a spin stabilized, liquid fueled, single stage vehicle which used hypergolic fuel. It was designed to provide the apogee firing for GEO insertion for DSCS-3 satellites, which did not have an apogee propulsion system. IABS featured solar arrays to remain operational and in orbit for up to 12 days although it was never used for so long missions.
