  1. Reaction Wheel with Embedded MEMS IMU

    SBC: Milli Sensor Systems and Actuators, Inc.            Topic: S405

    Reaction wheels are used to stabilize satellites and to slew their orientation from object to object with precision and accuracy by varying the rotational speed of the wheels. Three or four wheels are usually used with three of them aligned along orthogonal axes. The degree to which pointing stability is achieved depends on the stability of the wheels' angular momentum vectors while spinning, ...

  2. Robotic Vehicle Proxy Simulation

    SBC: Energid Technologies Corporation            Topic: X101

    Energid Technologies proposes the development of a digital simulation to replace robotic vehicles in field studies. It will model the dynamics, terrain interaction, sensors, control, communications, and interfaces of a robotic vehicle with the goal of supporting validation and training. The simulation will be very easy to use by simple execution on a networked PC. It will connect to NASA's ...

  3. Fast Neutron Dosimeter for the Space Environment

    SBC: Radiation Monitoring Devices, Inc.            Topic: X1401

    Model calculations and risk assessment estimates indicate that secondary neutrons, with energies ranging between 0.5 to>150 MeV, make a significant contribution to the total absorbed dose received by space crews during long duration space missions [1-3]. Advanced scintillation materials, which exhibit radiation type and mass dependent emission times, coupled to SSPM detectors, provide the optim ...

  4. Magnesium Based Rockets for Martian Exploration

    SBC: Busek Co., Inc.            Topic: S308

    In the proposed Phase II program, we will continue the development of Mg bipropellant rockets for Martian PAV applications. In Phase I, we proved the feasibility of this game-changing technology. Through chemical analysis, we determined that Mg can be combusted with CO2 condensed in-situ from the Martian atmosphere to yield Isp ~240 s. We then successfully demonstrated a low fidelity Mg-CO2 roc ...

  5. In-Flight and Pre-Flight Detection of Pitot Tube Anomalies

    SBC: Analysis And Measurement Services Corporation            Topic: A110

    The health and integrity of aircraft sensors play a critical role in aviation safety. Unfortunately, inaccurate or false readings from these sensors can lead to improper decision-making resulting in serious and sometimes fatal consequences. The research performed in Phase I demonstrated the feasibility of using advanced data analysis techniques to identify anomalies in Pitot tubes resulting from ...

  6. Advanced Bayesian Methods for Lunar Surface Navigation

    SBC: Autonomous Exploration, Inc.            Topic: O403

    The key innovation of this project is the application of advanced Bayesian methods to integrate real-time dense stereo vision and high-speed optical flow with an Inertial Measurement Unit (IMU) to produce a highly accurate planetary rover navigation system. The software developed in this project leverages current computing technology to implement advanced Visual Odometry (VO) methods that will acc ...

  7. Low Mass Low Power Hall Thruster System

    SBC: Busek Co., Inc.            Topic: S304

    In NASA is seeking an electric propulsion system capable of producing 20mN thrust with input power up to 1000W and specific impulse ranging from 1600-3500 seconds. The key technical challenge of the topic is the target mass of 1kg for the thruster and 2kg for the power processor (PPU). In Phase 1 Busek develop an overall subsystem design for the thruster/cathode, PPU and XFS. The feasibility of ...

  8. High Efficiency Hall Thruster Discharge Power Converter

    SBC: Busek Co., Inc.            Topic: S304

    Busek leveraged previous, internally sponsored, high power, Hall thruster discharge converter development which allowed it to design, build, and test new printed circuit board converter within this Phase 1 effort. The new converter consists of two series or parallel boards (slices) intended to power NASA GRC HiVHAC thruster or other similarly sized EP devices. The converter accepts 80 to 160V in ...

  9. High-Temperature, Wirebondless, Ultra-Compact Wide Bandgap Power Semiconductor Modules for Space Power Systems

    SBC: APECOR, INC            Topic: S305

    Silicon carbide (SiC) and other wide band-gap semiconductors offer great promise of high power rating, high operating temperature, simple thermal management, and ultra-high power density for both space and commercial power electronic systems. However, this great potential is seriously limited by the lack of reliable high temperature device packaging technology. The objective of this proposed resea ...

  10. UCDS Based Stable Injector Design

    SBC: GLOYER-TAYLOR LABORATORIES LLC            Topic: X1001

    History has repeatedly shown that combustion instability is the greatest technical risk faced in any chemical propulsion development program. The UCDS Process addresses this issue by using a rigorous physics-based analytical framework to decompose the complex flow field inside a chemical propulsion device, such as a liquid or solid rocket, in a way that allows rapid simulation of the dynamic behav ...
