This hands-on course aims to provide attendees with a solid understanding of the fundamentals of satellite timing and navigation (satnav) software receivers and associated signal processing. The course is divided into multiple modules, each comprised of a short lecture followed by the completion of a Python project that reinforces the concepts and techniques covered. By the end of the course, attendees will have an easy-to-use satnav software receiver running on their laptop that takes multiband live-sky sampled data files, acquires and tracks visible open satnav signals and outputs signal observables. This open-source code may be further extended to support numerous SDR based research applications.
Topics covered:

This course will provide an overview of Indoor Positioning and Indoor Navigation (IPIN) methods including, geometry-based positioning, scenario analysis (such as fingerprinting), proximity detection and dead reckoning.
Starting from the markets and applications using IPIN, we will introduce the popular technologies and related sensors including: radio signals, inertial measurements and mechanical waves etc., used in indoor positioning methods. Then, an IPIN framework will be introduced that consists of the source space, algorithm space, and integration. After introducing the single point positioning (SPP), we will discuss dead reckoning (DR).
Regarding the data sources of SPP, the course will separate the sources into homogeneous sources (geometry based) and heterogeneous sources (scene matching/analysis based). The former ones contain the measurements model of RSS-ranging, AOA, TOA and TDOA; while the latter ones contain the fingerprint and other transformed data sources that are used to match with pre-surveyed databases. Afterwards, the algorithms for SPP including, LS, NLS, ML, MAP and MMSE are introduced. The error and limitation of the SPP will be discussed. The popular DR using inertial and visual sensors, namely PDR and VO, will also be discussed before the sensor integration. Integration based on HMM, EKF and PF will be briefly introduced.
The course will conclude with a discussion on the future direction of indoor positioning system with the coming IoT and 5G era.
This course is suitable for entry-level R&D students, researchers and engineers; and managers and executives desirous to start a new project/application based on IPIN.
Dr. Li-Ta Hsu, born in Taiwan, is an assistant professor in Hong Kong Polytechnic University where he directs the Intelligent Positioning and Navigation Lab focused on the navigation for pedestrian and autonomous driving in urban canyons.

The revolution in autonomous vehicle development is providing novel solutions in an ever-growing range of applications. A critical component of autonomous vehicle design is the navigation system, which is required to provide a robust, accurate, navigation solution in a wide-range of operating environments. In this short course, we explore the concepts and technology associated with developing and testing navigation systems for autonomous vehicles by combining nonlinear multi-sensor fusion techniques and artificial neural networks (i.e., deep learning).
The course begins with an overview of sensors commonly used for autonomous systems including inertial sensors, GNSS, laser scanners, and image-based sensors. The associated error models are developed for each sensor and examples are presented regarding performance using experimental data. Next, core nonlinear filtering techniques are developed which support integration with the output of deep learning algorithms.
Finally, an overview of deep learning approaches for autonomous system navigation and associated performance capabilities is presented. The tutorial will begin with an overview of artificial neural network frameworks including, convolutional neural networks (CNN) and recurrent neural networks (RNN). The development will include both a theoretical and algorithmic perspective along with a review of hardware requirements for real-time implementation. Emphasis will be placed on designing a deep learning-based approach for ground vehicle navigation using a monocular camera sensor and open-source data.
