Fundamentals of Inertial NavigationThe Fundamentals of Navigation course will provide the student with an overview of the topics required to understand and implement a strapdown navigation system. The course is divided into two sections sensor modeling; and strapdown navigation. The course focuses on the

implementation, not on the derivation of the equations. Matlab/Simulink models may be provided to assist the student understanding the concepts described in this course. Sensor Modeling provides a brief description of gyro and accelerometer modeling. This course will not cover specific sensor technologies, but rather how to model any gyro or accelerometer from a system perspective. Modeling of deterministic errors such as bias, scale factor, and non-linearity; and stochastic errors will be discussed. The stochastic errors discussion will include a description of how to interpret Allan Deviation plots and modeling of the sensor errors using random Walk, Gauss Markov processes. Several examples will be presented, including guidelines for interpreting manufacturer’s product brochures as they pertain to modeling inertial sensors.Strapdown Navigation describes the implementation of a wander azimuth frame strapdown navigation implementation. This includes a description of the reference frames used in a typical strapdown navigation system, earth model and corrections for earth induced rates and acceleration. Transformation matrices and the integration of these matrices is discussed.

Introduction to GNSS Remote Sensing; Reflectometry and Radio Occultation

Recent developments and the current state of the art in Earth remote sensing using reflected (GNSS-R) and occulted (GNSS-RO) signals. GNSS signals experience attenuation, delay spread, and polarization change upon reflecting from ocean, terrain,

or ice surfaces. These changes are dependent on a number of variables, including ocean winds, soil moisture, vegetation and ice classification. Variation in the atmospheric index of refraction bends the GNSS signal path during rising or setting occultations as a function of the temperature and moisture profile. GNSS-R experiments were first conducted from aircraft (1998-2002), followed by the UK-DMC satellite demonstration in 2004. Recently, NASA selected the CYGNSS constellation to observe tropical storm development and ESA selected the PARIS In-Orbit Demonstrator for satellite altimetry. Approval of these missions begins the transition of GNSS-R from experimental proof of concept to operational remote sensing. GNSS-RO has been operational on the COSMIC constellation since 2006, providing important data for global weather forecast models. Occultation measurements from aircraft have been recently demonstrated. Both methods enable many types of variables to be measured to be made using small, low-cost receivers with low-profile patch antennas, due to the reutilization of the highly stable GNSS signal. Course Level: This tutorial is intended for anyone interested in the measurements obtainable from GNSS-R or GNSS-RO for potential application within their own field. It is also appropriate for GNSS systems engineers who desire to identify technology needs and trends in developing new instruments, algorithms, and missions to support future applications of these promising new remote sensing techniques. A basic understanding of how GNSS works is desirable, but not required. In order to make this material accessible to the widest engineering and scientific audience, the tutorial will be based around physical arguments with a minimum of mathematical derivation. A bibliography will be provided to students interested in learning more.Dr. James Garrison is an associate professor of Aeronautics and Astronautics at Purdue University. He earned a PhD from the University of Colorado and is the author or co-author of 26 journal articles, 54 conference proceedings, six US Patents, and the chair of GNSS+R 2012. He has received several awards, including a NASA New Investigator grant and the ION Early Achievement Award. Prof. Garrison’ research is in remote sensing using GNSS and signals of opportunity.

Sensor Integration for Personal NavigationA review of navigation sensors and techniques suitable for personal and pedestrian navigation, including selected Artificial Intelligence (AI) methods. Personal navigation (PN) is defined as navigation for military and emergency personnel, while pedestrian navigation refers to location/navigation/tracking of all other types of mobile users. The core technologies in personal navigation systems are the Global Positioning System (GPS) and inertial sensors, which provide seamless highly accurate navigation in open-sky environment, where

GPS signals are available. To facilitate navigation indoors or in GPS-denied environments, additional navigation and imaging sensors are required. An overview is provided of some of these technologies, such as, wireless local area network, IR and RF transponders, and ultra-wideband (UWB) networks, and a basic introduction to 2D and 3D active and passive imaging sensors.An example design that includes implementation and performance assessment of a personal navigation system prototype that uses GPS, inertial measurement unit (IMU), UWB, digital barometer, magnetometer compass, and human locomotion model as well as 2D/3D imaging sensors to provide position and attitude estimates to support navigation and tracking of military and rescue ground personnel will be presented. On the algorithmic side, the focus is on the indoor operation and performance of the navigation filter. A dead reckoning (DR) navigation approach will be presented that employs a human locomotion model using an adaptive knowledge-based system (KBS) based on AI techniques and tracking data obtained from 2D and 3D imaging sensors. The KBS is trained during the GPS signal reception, and then supports navigation under GPS-denied conditions. System design, as well as a summary of the performance analysis in the mixed indoor-outdoor environments, with the special emphasis on DR performance, will be discussed.Course Level: Beginner to IntermediateDr. Dorota Grejner-Brzezinska is a professor and chair, Department of Civil, Environmental and Geodetic Engineering, and director of the Satellite Positioning and Inertial Navigation (SPIN) Laboratory at The Ohio State University. Her research interests cover GPS/GNSS algorithms, GPS/IMU and other sensor integration for navigation in GPS-challenged environments, sensors and algorithms for indoor and personal navigation, Kalman filter and non-linear filtering.

He has published over 300 papers in various journals and proceedings.

Fundamentals of Nonlinear Recursive Estimation

This course will present on overview of estimation techniques suitable for systems with nonlinearities that are not well-suited to traditional linear or extended Kalman filter algorithms. The course begins with an overview of the generalized recursive estimation problem and associated notation and

conventions. The limitations of applying linear theory to nonlinear problems is addressed, along with techniques for compensating for these adverse effects, including a brief overview of the traditional extended Kalman filter and Gaussian sum techniques. The mathematical effects of system nonlinearities on random processes are presented along with computational techniques for efficiently capturing this information, which serves as the foundation for the development of many nonlinear estimators. The unscented Kalman filter (UKF) and particle filters (PF) are presented and analyzed using multiple examples. Common limitations of nonlinear estimators are addressed and hybrid solutions are discussed. The course concludes with a discussion and qualitative comparison of the strengths and weaknesses of various recursive estimation techniques from linear Kalman filtering to particle filtering, and their applicability to various problem spaces. Numerous Matlab examples are presented to illustrate sample nonlinear estimation algorithms and performance. The Matlab source code will be provided for these examples along with the electronic version of the course notes.Course Level: This course will be presented at an engineering level with the goal of understanding the fundamental concepts behind current nonlinear estimation algorithms and how they compare to traditional approaches. The course is appropriate for engineers and scientists with linear and extended Kalman filter experience with an interest in the potential benefits of nonlinear estimation algorithms for difficult problems.Dr. Michael Veth, Ph.D., is currently the lead engineer and co-founder of Veth Research Associates where he provides expert consulting and training in estimation theory and alternative navigation techniques.
