Demonstrator Technical Description • Microwave Experiment Source: 2 TWTs @12 Ghz Power transmitted 250W Antenna: Fixed phased array design (0.7 m square ) Fine Pointing: Electronically or mechanically Subsatellite: Deployable/inflatable rectenna (e.g. 2-3 meters diameter) Sensor telemetry relay to Eureca comms. • Laser Experiment Source: e.g. Solid state diode or other Power transmitted 10-20 Watts Fine pointing: Adaptive optics or gimbal system Subsatellite: Frequency-tuned solar cells, plus comer cubes Sensor telemetry relay to Eureca DHS 6.1.2 Spacelab E-l The range of missions are very similar to those presented in Section 6.2 below. Differences in how the experiment will be conducted and observed may be possible because the USS will be under the control of the Spacelab crew and because active thermal cooling may be available, enabling higher power levels. Potential problems are with the conflicting requirements between the needs of the demonstrator and the other experiments on the USS. If the demonstrator used either the USS or Hitchhiker G, it may be possible to use the RMS to hold a small receiver above the experiment, analogous to the original versions of the Texas A&M CSP experiment (Figure
