Appendix L: <strong>Tether</strong> Boost Facility Design Final Report4. Perform ∆V burn to raise apogee of Control Station to slightly elliptical orbit• Burn to raise apogee (500-1000km, limited by amount of propellant in upperstage)• Apogee also limited by mass of demo <strong>Tether</strong> Boost Facility hardware (seeFigure 5.7)• Possibly use only half of propellant for orbit raising and save rest for abortdeorbit• Burn to trim orbitFigure 5.7. Delta II elliptical orbit payload delivery capability.5. Spin-up Control Station• Perform star alignment calibration• Maneuver to start attitude• Spin-up the Control Station using onboard thrusters6. Deploy <strong>Tether</strong> and Grapple Assembly with simple payload attached (see Figure 5.8)• Deploy <strong>Tether</strong> and Grapple Assembly• Trim Control Station attitude rate• Apply current to tether as necessary to maintain or increase rotation rate• Repeat above steps until tether fully deployedL-35
