Title: Satellite Navigation and Sensing
Satellite-based navigation has impacted nearly every aspect of our modern society. Yet, this powerful technology relies on extremely low power, vulnerable signals traversing a vast space to reach receivers on the Earth surface or near-Earth space environments. Many complex elements interfere with the signals along their propagation path, including plasma in the upper atmosphere, water vapor in the lower troposphere, as well as physical objects and electromagnetic sources in the user environments. These nuisance factors degrade and limit navigation systems performance. Understanding their effects on navigation signals is the pre-requisite for developing robust navigation technologies that can mitigate these elements impact. Moreover, these effects enable satellite navigation signals to function as signals-of-opportunity for low cost, distributed, passive sensing of our space and local environments. This presentation will first discuss efforts in developing a worldwide network of software-defined sensors to capture and characterize the effects of the space and local environments on satellite navigation signals, followed by the latest technology development to mitigate these effects, and finally case studies demonstrating the potential powerful applications of the satellite navigation sensor network for environmental monitoring.

Title: Signal Processing in a Gamma Ray Observatory
The SWGO scientific collaboration plans to build a Gamma Ray Observatory in the Southern Hemisphere. The ideal place to build the Observatory must be at a height of 5000 meters above sea level. In this presentation I will describe the detectors and the detection process. I will emphasize signal processing. The signals consist of very fast pulses, on the nanosecond scale.

Title: Revisiting ionospheric forecasting and estimation: Applications to ionograms, storms, and density reconstruction
Modern technology has allowed us to expand the coverage of our measurement of space. On the ground, one way this has manifested is through the popularization of software-defined radio and its applications to sense the ionosphere. Nevertheless, optimal ways to harness these new data are still under active research. Furthermore, these novel measurements often come with new challenges that are forcing us to extend our standard estimation models. In this talk, I will present some research projects exploring new ways of tackling some classic estimation problems. First, I will show some preliminary results on the use of neural networks to forecast ionograms and Spread-F occurrence. Then, some approaches to potentially improve previous work on ionospheric refraction tomography for the estimation of electron density distributions using oblique ionospheric sounders. These projects are being developed in collaboration with Jicamarca scientists and Peruvian undergraduate students.
Enrique studied physics in the Pontificia Universidad Catolica del Peru and worked in the Jicamarca Radio Observatory for two years. In 2014 he went to Cornell to work in the space plasma physics group under the supervision of David Hysell. He continues working there now as a postdoc associate.

Title: Experiments in Sensing and Signal Processing for Autonomous Navigation
The emergence of autonomous navigation systems has spurred many innovations in the design of sensing, computing, communication, and control systems. In this talk, we will present experiments related to the design and development of autonomous navigation platforms and algorithms based on neural networks. In the first experiment, the design and performance of a simple camera-based system deployed in large vehicles for collision avoidance will be presented. In the second experiment, results related to the identification of vehicles on Indian roads using traffic camera videos will be presented. A brief description of the efforts of building an open dataset for Indian road traffic will also be presented.

Title: Deep Space Network (DSN)
NASA’s Deep Space Network (DSN) provides communication services to spacecraft from beyond geostationary orbit to beyond our solar system, supporting missions that have extremely low data rates (10 bps) to missions that have data rates higher than 100 Mbps. First, the DSN’s current capabilities are discussed. Some key design considerations are then reviewed. Finally, the near term and longer-term plans are shown.
