Description
Program was founded in 1982 in response to DoD's increasing dependence on space systems for navigation, communications, and intelligence gathering. Thus far, program has graduated the largest number of astronauts in the world.

Publication Development of a computer-controlled instrumentation for a thermal vacuum chamber(Monterey, California. Naval Postgraduate School, 1995-09) Hengst, Michael.; Space Systems (SP)In this thesis, a Tenney Space jr. Thermal Vacuum Chamber (TVAC) was modified in a way that allows complete control of the system and the performance of tests under space specifications by computer. To achieve this, both computer hardware and software were installed and modified and additional mechanical connectors were designed and installed. A large series of tests throughout all phases of this project was performed to test the equipment, to learn about the TVAC controls and to prove that the system is fully operational after the changes.Publication Design and Analysis of the Housing of the Communication Payload of the Petite Amateur Navy Satellite (PANSAT)(Monterey, California. Naval Postgraduate School, 1995-09) Gericke, Olaf; Space Systems (SP)The Naval Postgraduate School's (NPS) Space Systems Academic Group is developing the Petite Amateur Navy Satellite (PANSAT), a small satellite for digital store-and-forward communication in the amateur frequency band. This thesis describes the design and the analysis of the communication payload housing of PANSAT. The payload consists of four circuit boards. The main challenge is to provide enough stiffness and minimize electromagnetic interference within the small amount of space determined by other parts surrounding the housing. The design of this particular housing is especially demanding and requires paying a lot of attention to details. Many factors, including launch loads, board weight, component size, orientation, and mounting must be considered.A particular aspect of this housing is the fact that there are an unusual number of electrical connectors involved in this design. Complicating this issue is the extreme physical constraint imposed by the configuration of the satellite. The structure as well as the boards are analyzed using classical hand calculation methods and more sophisticated methods, using SDRC® I-DEAS design software. In addition, a finite element analyses is performed using the I-DEAS finite element application which allows to model all structures in great detail mathematically. It also permits to examine the behavior of these structures under all possible load conditions, static as well as dynamic. Another important aspect of this design is to guarantee manufacturability. The complexity of this housing makes it mandatory that the design be carried out in close cooperation with the machinist who is responsible for the actual manufacturing of these parts. The analysis results show that the structure of the housing is very robust and most likely will accommodate all the requirements.Publication Design and Implementation of the PANSAT Software Groundstation(Monterey, California. Naval Postgraduate School, 1995-09) Bartschat, Jens; Space Systems (SP)The PANSAT Software Groundstation enables a user to command and control PANSAT once it is in space, provided he has an IBM-compatible and WindowsOR or Windows NTOR capable computer with a serial interface and the necessary additional hardware. Via the implemented PAN SAT Command Language (PCL), the user will be able to access all PANSAT commands, thus control it, gather telemetry data or use its mail storing capability in an easy-to-use manner typical for Windows-based applicationsPublication Operationally Responsive Space (ORS) architecture for the year 2025(Monterey, California. Naval Postgraduate School, 2008) Hansen, K.; Kennedy, S.; Ledoux, S.; Senn, M.; Turner, J.; Rayburn, J.; Kacala, J.; Hatcher, B.; Widmann, M.; Carson, J.; Space Systems (SP); National Reconnaissance Office (U.S.); Space SystemsThe Unites States' first space systems programs, to include launch, ground, and space segments and their associated infrastructure, were initially developed to meet the requirements of the strategic users. Since the 1991 Gulf War, there has been a growing dependence on the capabilities and support delivered by those programs to meet requirements of non-strategic users. The current National Security Space (NSS) architecture makes it rather difficult and challenging for all but critical strategic users to fully capitalize on the available assets. Timelines that were once adequate to deliver strategic capabilities are now not sufficient to allow a broader range of users to realize the benefit from using the available space systems. In addition, the non-strategic users run into challenges when they attempt to change the tasking requirements that would enable them to receive associated products / services that are useful and timely. With the identified gaps in the current NSS environment, the Integrated Product Team (IPT), consisting of ten active duty military students, sought solutions to make space more Operationally Responsive to its customers by 2025. Due to limited time and assets, the IPT narrowed the focus of the project to the four Joint Publication (JP) 3-14 Joint Doctrine for Space Operations mission areas of Space Support, Space Control, Force Enhancement, and Force Application. During this project, the IPT defined Operationally Responsive Space (ORS) from its perspective, developed the requirements to meet the identified NSS gaps, selected the final alternatives to satisfy those requirements, and suggested an implementation plan. While in the architecture process, the IPT conducted an in-depth evaluation of the original [61] alternatives based on Responsiveness, Risk, Capability, and Cost. After building a foundation for further analysis, a total of 16 alternatives were chosen for the final ORS architecture. The IPT's leading alternative that provided the most responsiveness was to create a Single Space Agency. The other alternatives range from establishing joint ventures with other countries to developing hypersonic lift vehicles to transport troops and supplies. A detailed list of the Sweet Sixteen can be found in Appendix E.
