Electric propulsion has often been described as the propulsion system of the future, usually with the appended remark "and always will be". Some forms of electric propulsion have been operational for years, such as arcjects and ion thrusters for north-south stationkeeping. More recently, small amounts of high altitude orbit raising and plane change have been demonstrated on operational satellites with large ion thrusters. However, these are but the first steps toward massive application of electric propulsion for earth-orbiting and interplanetary spacecraft. As we show in this handbook, for each electric propulsion mission the proper matching of launch vehicle and electric propulsion system is essential to secure optimum results in terms of increased payload and/or reduced launch cost. Spacecraft design is also critical to the selection process, especially with respect to spacecraft power/mass ratio. The various types of electric propulsion that are currently available for reliable spacecraft applications are described in Section 1. Physical and performance data are provided so that realistic applications can be examined. Quick look methods for determining the applicability of electric propulsion to simple missions are set forth in detail. In this publication we proceed through the minor mission applications to reasonable amounts of orbit raising to low earth orbit, medium earth orbit, and finally geostationary applications. Simplified but detailed calculations are provided for all examples so that the reader can apply these methods to their specific applications. Trade-off curves for orbit-raising to geostationary orbit are provided, with explanations of how to apply these to obtain practical results. Hand held calculators and simple computer programs are the only tools needed.
