    Comparing the capabilities and performance of the ultra high frequency follow-on system with the mobile user objective system
    (Monterey, California. Naval Postgraduate School, 2011-06) Matassa, Christopher K.; Huynh, Thomas V.; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Systems Engineering (SE); Scott, Alan D.
    The Mobile User Objective System (MUOS) is the DoD's next generation military Ultra High Frequency (UHF) Satellite Communication (SATCOM) system being designed to augment and eventually replace the currently oversubscribed UHF Follow-On (UFO) System. MUOS adapts a commercial third generation (3G) Wideband Code Division Multiple Access (WCDMA) cellular phone network architecture and combines it with geosynchronous satellites (in place of cell towers) with the goal of providing a more capable UHF SATCOM system. This research aims at investigating the differences between the legacy UFO and MUOS systems in terms of network performance and quality of service. Using modeling and simulation of both systems against input traffic loads of a hypothetical Joint Task Force, a comparative study of the performance and capabilities of each system is conducted to quantify the extent of MUOS improvements. The study finds that MUOS can tolerate a traffic demand rate of about 83 calls/messages per second whereas UFO saturates at roughly 4 calls/messages per second. MUOS's ability to offer a higher level of quality of service, assured access, and increased capacity will enable more tactical users to share timely information while reducing the uncertainty that they will be able to communicate with their intended recipient. Faster service data rates reduce delays in relaying information during time critical operations. The system represents a paradigm shift in UHF SATCOM from circuit-based, assigned networks to on-demand, global IP-based, net-centric networks. This study has shown that, as specified in its designs, MUOS can provide a level of system performance that will place the system in a preeminent role for the network-centric operations critical to the mission effectiveness of today's military.

    A systems engineering design analysis of a U.S. Army secure storage system
    (Monterey, California, 2002-03) Shaw, Trevor W.; Matthews, David F.; Marvel, Orin E.; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS)
    As the Army develops and fields new or improved tactical equipment for the soldier, the challenge of providing for its security, unit-level maintenance, availability, and accountability will exceed the capacity of present systems. This new or improved tactical equipment will include a number of high-cost, technically advanced items that will present storage and other logistical challenges. In garrison, the fixed facilities at unit level are inadequate for the projected need (both quantitatively and qualitatively). Finally, there are no current systems specifically designed to provide security, protected storage, availability, and accountability of sensitive and high-value non-sensitive items during training or operational deployments This thesis uses a tailored application of the systems engineering process to develop a design for a U.S. Army secure storage system. This study investigates the user's requirements for such a system, as well as requirements and constraints derived from security regulations, military and commercial intermodal transportation methods, and current Army facilities and force structure. It then examines existing Government and commercial equipment to assess their suitability for satisfying secure storage and transportation requirements. Ultimately, this system engineering analysis produces a physical architecture of a mobile secure storage system, as well as selected items of the system architecture.

    Detection and parameter estimation of chirped radar signals
    (Monterey, California. Naval Postgraduate School, 2000-01-10) Hippenstiel, Ralph Dieter; Fargues, Monique P.; Moraitakis, I.; Williams, C.; Electrical and Computer Engineering (ECE); Graduate School of Engineering and Applied Science (GSEAS); Electrical and Computer Engineering
    This work investigated the detection of pulses and extraction of modulation parameters from different types of time-limited chirp signals, as may be found in pulse- compression radar signals. The work is split into two parts. The first part examines the pulse detection problem, i.e., the detection of the pulse start/stop times. Such information can be used to determine the pulse width and repetition rate of the radar systems under investigation in an automated fashion. We compare the robustness of three TCF-based schemes and an envelope detection algorithm in noisy environments.

    Atlantic water on the Chukchi Shelf
    (Monterey, California. Naval Postgraduate School, 1976-12) Bourke, Robert H.; Paquette, Robert G.; Oceanography (OC); Graduate School of Engineering and Applied Science (GSEAS); Research and Sponsored Programs Office (RSPO); Oceanography
    An anomalously warm saline layer in the bottom of the shallow Chukchi Sea in August 1975 is believed due to a surge which drove water from the Atlantic Layer of the Arctic Ocean up onto the shelf. Two earlier occurrences of this kind of water in the Chukchi Sea have been identified in historical data.

    Biology and ecology of encrusting bryozoans in Monterey Harbor
    (Monterey, California. Naval Postgraduate School, 1970-10-20) Haderlie, Eugene Clinton; Oceanography (OC); Graduate School of Engineering and Applied Science (GSEAS); Research and Sponsored Programs Office (RSPO); Oceanography
    The encrusting bryozoans Celleporaria brunnea, Cryptosula pallasiana and Tubulipora tuba are the dominant bryozoans and often the dominant fouling organisms in Monterey harbor. By using panels as collecting surfaces, the general biology and ecology of these three species have been investigated. All three settle and grow at depths from the surface down to 25 feet but the optimum depth for settlement and growth is just below the low tide mark. Release of larvae and settlement occurs erratically throughout the year with no species showing a 'season' for settlement. Growth rates have been measured throughout the year for each species. The spreading colonies of Celleporaria brunnea and Cryptosula pallasiana have a definite inhibiting influence on the settlement of barnacle and serpulid larvae, and often cover and smother previously settled barnacles, serpulids, and borers such as Limnoria. Celleporaria colonies were preyed upon by Thysanozoon californicum. a flatworm that closely mimics the color and texture of the bryozoan

    NPS TINYSCOPE program management
    (Monterey, California. Naval Postgraduate School, 2010-09) Turner, Christopher Gordon.; Romano, Marcello; Newman, James Hansen; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Space Systems Operations
    This master's thesis introduces the program management and concept of operations of the TINYSCOPE Program. TINYSCOPE is a 6U CubeSat designed as a low-cost and easily replaceable imaging spacecraft that can produce tactically relevant imagery data. Tactical requirements in this context would emphasize "good enough" image resolution with a rapid-response tasking loop and high revisit rate. The TINYSCOPE project intends to demonstrate the utility of small, risk tolerant spacecraft for tactical imagery. The program management section of the thesis discusses the relationships of cost, performance, risk, and schedule and the impact of each on the program. The program's successes and failures are examined to glean lessons for future program managers of university projects. The remainder of the thesis develops a comprehensive concept of operations for the prototype spacecraft. Areas of discussion include overviews of the ground, space and launch segments of the mission architecture, and proposed conduct of operations for those segments. Finally, relevant program management and systems engineering documentation are presented as appendices.

    Three Approaches to Space Systems Acquisitions and their Application to the Defense Departments Weather Satellite Program
    (Monterey, California. Naval Postgraduate School, 2012-03) Phillips, Wellington V.G.; Langford, Gary; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Systems Engineering Management; Bonesteele, Raymond
    For more than a half century, the United States government has been acquiring and launching satellites. However, throughout these years, there has been a shift in the space systems acquisitions model, from acquiring greater quantities but less complex satellites, to fewer quantities but drastically more complex individualized satellites. Within the past two decades, when a new satellite was to be built, whether as part of an existing generation of satellites or the first of its kind, it appeared that the acquisition process starts over from the beginning as if it was the first time building a satellite. This shift in the model has resulted in these individualized systems being extremely costly and taking a long time to be produced. The acquisition of the Defense Departments Weather Satellites is one such example. This author asserts that effective systems acquisition requires a system engineering-inspired approach. The result of systems engineering guidance is to synthesize general principles from case studies. Therefore, this thesis researched the history of some Air Force Space acquisitions programs, current factors affecting the way systems are acquired, and new approaches (Fast, Inexpensive, Simple, Tiny [FIST], and Evolutionary Acquisition for Space Efficiency [EASE]) that are intended to remedy the aforementioned problems. In addition, Toyotas process for producing new vehicles models was also reviewed. These three approaches were then applied to the Defense Departments Weather Satellite program to develop recommendations for its follow-on programs acquisition strategy.
