Each SPM is responsible for coordinating the work of the various sub-contractors in the SPM's field of work. Concerning the interfaces with other program elements, the SPMs report to the System Engineer, who will coordinate any necessary exchange of information between SPMs. The SPM shall closely work together with the Product Assurance department. Principal Investigator: A Principal Investigator (PI) is dedicated to one specific experiment in the area of rectenna or payload research. The PI reports and is responsible to both the project scientist and the sub-program manager. The parameters will be given to the PI by the sub-program manager. The Space to Space Beaming Demonstrator ($80M) Management Specifically about this project, please note that: The objective of this design example is to beam power by microwaves to a simulated micro gravity laboratory. More specifically, the objective is to beam power from the Russian MIR space station to a PROGRESS transport spacecraft over a distance of about 80m (also refer to section 10.2). The elements relative to the management structure of the Space to Space beaming design ($80M) example are as presented below (also refer to Figure 5.3): The Director General (DG) with the accord of the Board of Governors, will have to plan the development of its organization to permit the management and realization of the Space to Earth project ($800M). Public Relations will play a specific role in this project by conducting different lobbying campaigns to insure funding for the activities and to obtain public and political support. Finally, the Systems Engineering (SE) function will be a task team of Engineers and scientists responsible for performing all classical SE functions such as overall system definition and configuration control. It will create requirements documents that define both functional and interface requirements imposed by the system on each element. Members of the SE will be responsible for monitoring the development work of the various subcontractors. They will have to assure that all the elements of the sub-programs meet the requirements specified. They will be responsible for the quality of the products developed and will control the configuration. They will have to perform the necessary tests to verify the quality and functionality of the different elements of the system and to test the complete system. The major systems (and subsystems associated) to be developed are the antenna, the transmitter, the rectenna, the receiver, the interfaces and other systems. The SE members will be responsible for preparing the system for transport to the launching site and providing the necessary technical support of the launch. The SE will finally have to test and analyze the data obtained following the experiment. System analysis and evaluation is required. The Space to Earth Beaming Demonstrator ($800M) Management The Space to Earth beaming design example specified in section 10.4.6 will demonstrate the feasibility of space to Earth power beaming. Upon successful completion of this demonstrator, a Space Solar Power Program will eventually evolve. It should be clear that all of the above mentioned responsibilities of the functions/ departments are heavily dependent on the size of the program. In case of the Space to Earth beaming demonstrator, the work will be divided according to the organization chart of Figure 5.1, however, the size of the different departments will be much smaller than it will eventually be for the commercial program. The function of project scientist is of utmost importance during the demonstrator projects, because the scientific data from the demonstrator will serve as a basis for the commercial program. As is also described in the previous section, the public relations should already be fully functional at the time of the demonstrator. It is, for example, not necessary to have a marketing directorate in the beginning of the demonstrator project, whose objective is mostly to serve as a technical and commercial viability demonstration, instead of being a really commercial program. The marketing directorate does of course become more important as time passes and should be fully operational when the commercial program starts.
