Description
Our purpose is to prepare our students to lead in transformation and manage change in tomorrow’s complex and technically challenging world. We fulfill that purpose by empowering student minds with advanced knowledge culled from cutting-edge, defense related research; by blending classroom experiences into a hands-on pedagogy that links theory and reality; and by teaching and inculcating creative, innovative thinking that prepares our students to continue to learn, grow, adapt and lead in future, unknown environments. Our graduates are more than just well educated engineers and scientists; they are innovative leaders of transformation and creative solvers of tomorrow’s problems.

    Transit Sat
    (Monterey, California: Naval Postgraduate School, 2018-01-24) Space Systems Academic Group (SSAG); Graduate School of Engineering and Applied Science (GSEAS); Space Systems Academic Group (SSAG)
    The Transit satellite system, sponsored by the Navy and developed jointly by DARPA and the Johns Hopkins Applied Physics Laboratory, under the leadership of Dr. Richard Kirschner at Johns Hopkins, was the first satellite-based geopositioning system. Just days after the Soviet launch of Sputnik 1, the first man-made earth-orbiting satellite on October 4, 1957, two physicists at APL, William Guier and George Weiffenbach, found themselves in discussion about the radio signals that would likely be emanating from the satellite. They were able to determine Sputnik's orbit by analyzing the Doppler shift of its radio signals during a single pass. Discussing the way forward for their research, their director Frank McClure, the chairman of APL's Research Center, suggested in March 1958 that if the satellite's position were known and predictable, the Doppler shift could be used to locate a receiver on Earth, and proposed a satellite system to implement this principle.

    Development of Navigation Solution for NPSAT1
    (Monterey, California. Naval Postgraduate School, 2014-07) Leopold, Philipp Clemens; Panholzer, Rudolph; Space Systems Academic Group (SSAG)
    The thesis develops a Navigation Solution for NPSAT1 based on a new approach.The necessary orbit determination, which is normally done by NORAD with high precision laser measurements, is directly implemented in NPSAT1.The GPS receiver measures the orbital state vector allowing to calculate a two-line element set based on the theories from SGP4.These Orbital Elements are used to predict the position for the next orbit, until a new orbit determination is performed. The implemented model of Earth’s magnetic field needs the current position as input in order to provide the attitude control system with information about the current magnetic field vector.This new approach makes the transmission of the two-line element set from the ground station unnecessary.Several tests showed that the Navigation Solution provides a precise time, position and magnetic field vector to other programs and experiments, consuming only little energy as the GPS receiver is only used once per orbit.

    Configurable Fault-Tolerant Processor (CFTP) for Space Based Applications
    (2003-08) Ebert, Dean A.; Hulme, Charles A.; Loomis, Herschel H.; Ross, Alan A.; Space Systems Academic Group (SSAG); Graduate School of Engineering and Applied Science (GSEAS)
    The harsh radiation environment of space, the propensity for SEUs to perturb the operations of silicon based electronics, the rapid development of microprocessor capabilities and hence software applications, and the high cost (dollars and time) to develop and prove a system, require flexible, reliable, low cost, rapidly developed system solutions. Consequently, a reconfigurable Triple Modular Redundant (TMR) System-on-a-Chip (SOC) utilizing Field Programmable Gate Arrays (FPGAs) provides a viable solution for space based systems. The Configurable Fault Tolerant Processor (CFTP) is such a system, designed specifically for the purpose of testing and evaluating, on orbit, the reliability of instantiated TMR soft-core microprocessors, as well as the ability to reconfigure the system to support any onboard processor function.

    A Design Template for GAS Satellite Payloads
    (1988-09) Sakoda, Daniel; Space Systems Academic Group (SSAG); Graduate School of Engineering and Applied Science (GSEAS)
    The Naval Postgraduate School has designed a small, low cost, general purpose satellite bus, ORION. An investigation of the structural requirements has been done for ORION as an extended Get Away Special (GAS) canister payload. The structure must be able to withstand the design limit load of 6.0 g's acceleration in ± X and ± Y, and a limit load of 10.0 g's in the ± Z. The structure must also have modal vibration greater than 35 Hz. A finite element analysis in linear bending considers an aluminum stiffened cylinder with two equipment plates and a top plate. Considerable weight reduction from the original design results. The structure configured for ORION may be helpful to other GAS payload users as a design template for similar satellites.

    CubeSat Launchers, ESPA-rings, and Education at the Naval Postgraduate School
    (2007-08) Newman, James; Sakoda, Daniel; Panholzer, Rudolf; Space Systems Academic Group (SSAG); Graduate School of Engineering and Applied Science (GSEAS)
    An effort is underway at the Naval Postgraduate School (NPS) to leverage its unique position as both a military research institution and a graduate university interested in educational outreach. We are working to simultaneously incorporate the use of CubeSats into our educational and space research program and to enable the access of other student-built CubeSats to DoD launches. To launch CubeSats, NPS is designing a CubeSat launcher compatible with the ESPA (EELV Secondary Payload Adaptor) interface. Through partnerships with universities and other DoD collaborators, NPS is seeking to maximize the potential for launching CubeSat payloads.
