This book was released on 1980 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study uses a computer simulation of a strapdown laser gyro inertial reference system to analyze the errors generated as a result of highly dynamic flight profiles. A stochastic error model using state-of-the-art inertial sensors is developed in detail and implemented in software. SOFE, a generalized simulation program, was used to implement both a Monte Carlo simulation and a covariance analysis. The Monte Carlo method was selected to perform the error analysis. Two highly dynamic flight trajectories were developed using the flight profile generator, PROFGEN. The PROFGEN program itself was modified to include an aircraft roll time constant and a roll-only maneuver. The errors generated in the inertial reference system as a result of these flight trajectories were investigated. Both an error budget and an analysis of the maneuvers inducing these errors were accomplished. Gyro error sources induced the most system error and coupled the dynamics of the flight trajectory into the variations of the error. Misalignment was found to be the major cause of both the accelerometer and gyro induced error. Successive maneuvers were found that reinforced system errors and other maneuvers were found that cancelled these errors. Also, some cases were found where the amount of system error varied with a change in heading.

This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing. house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

This book was released on 1979 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operation of a strapped-down inertial navigation system in a high dynamic environment was simulated. Its performance was assessed using a laser gyro and a quartz-flexure accelerometer as the sensors. Using deterministic values for the sensor errors, the effects of the sensor errors on the INS performance was assessed. Emphasis is placed on the effects that the sensor errors have on the INS errors in a high dynamic environment. Structural mode effects on INS performance are also evaluated. Following this an analysis of the sensitivity of the INS errors in position and velocity to each inertial sensor is determined. Using this sensitivity analysis, the sensor parameters required to obtain a performance specification of

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Inertial sensors, such as accelerometers and gyroscopes, have become ubiquitous in our daily lives and are found in a variety of devices and applications that require measurement of motion, direction, vibration and orientation. These integrated sensors benefiting from the tremendous advancements in microfabrication technology continue to grow rapidly providing efficient control and continuous monitoring in a variety of applications including smartdevices, automotive, aerospace, and industrial robotics. Here, both the choice of the fabrication technology and the design of the sensor devices play an important role to develop high performance MicroElectroMechanical Systems (MEMS) inertial sensors to insure stability, repeatability and accuracy of the measurements during operation. Literature review of MEMS inertial sensors reveals that many of these sensors are developed using full custom or proprietary micromachining processes. Till recently, standard pure-play MEMS processes had several limitations including choice of materials and lack of wafer-level vacuum packaging that made them incapable to support development of integrated inertial sensors with high performance specifications. Recently, the availability of standard pure-play MEMS processes that offer excellent advantages in high quality materials and advanced packaging could lead to development of new inertial sensors that can be readily mass-produced. These devices could help towards lowering the cost of devices with increased competition to existing players in the market and pursuing niche application areas that cannot be satisfied by available devices in the market. The present research aims to design, fabricate and characterize high performance novel integrated capacitive inertial sensors including both single axial and multi-axis accelerometer and a multi-axis gyroscope for angular rate measurement. The developed devices are based on two standard pure-play processes offered by Teledyne DALSA Semiconductor Inc. (TDSI). In 2013, TDSI introduced MEMS Integrated Design for Inertial Sensors (MIDIS) process, which is currently the only commercial MEMS process that includes ultra-clean wafer-level vacuum encapsulation of the MEMS devices at 10 mTorr. MIDIS process helps towards achieving a high Quality factor and reducing noise interference on the MEMS sensor devices. The developed inertial sensors in MIDIS process include a uniaxial accelerometer with ultra-low noise performance enabling resolution of 33mg over a high-g range of ±100g, tri-axial accelerometer with very low cross-axis sensitivity of 0.8%, and rate grade gyroscope with high Quality factor (> 50,000). This research is the first demonstration of wafer-level vacuum packaging of MEMS inertial sensors in a high volume pure-play MEMS process. " --
