Embry-Riddle Aeronautical University Showcase

The Embry-Riddle Coastline Dataset (ER-Coast) is designed for maritime machine learning research, including sensor fusion. ER-Coast introduces a diverse set of data using multiple sensing modalities. These include three LiDAR, three 8-megapixel color cameras, one 5.4-megapixel high dynamic range camera, two long-wave infrared cameras, and a GPS/IMU inertial navigation system. The captured data includes coastal waterways in the state of Florida during the day and at night. There are 36 separate sequences split across 4 days of collections, totaling over 5 hours of calibrated and timestamped data. A subset of this raw data has been annotated for the tasks of LiDAR semantic segmentation, image semantic segmentation, and image object detection. Intrinsic and extrinsic calibrations are available in the dissertation of https://commons.erau.edu/edt/741/, and the original calibration data has also been provided for users to generate their own calibrations. A paper with a focused discussion of ER-COAST will be released at a later date.

The repository includes TEC data, MAGIC-GEMINI modeled electron densities, and simulated TEC along real LOSs on 27th May 2017 at 19:30 UT. Description of data and simulation output is found in ReadMe.txt

System for Rapid Analysis of Ionospheric Dynamics based on GNSS TEC Signals (S-RAID) performs downloading, parsing, and processing of Global Navigation Satellite System (GNSS) signal measurements and their geometry of observations, calculation of slant and vertical total electron contents (sTEC and vTEC) and subsequent visualization for selected band-passes of fluctuations with periods shorter than two hours. In a routine operation, the System processes 15/30 sec GNSS signal measurements over Continental United States (CONUS) from ~2700 stations. Raw GNSS signal measurements are collected from public archives, including The Crustal Dynamics Data Information System (CDDIS), EarthScope/UNAVCO, National Oceanic and Atmospheric Administration (NOAA), and Scripps Institution of Oceanography's Orbit and Permanent Array Center (SOPAC). The System is oriented towards rapid access to GNSS sTEC/vTEC data for the investigation of traveling ionospheric disturbances (TIDs) of various nature, from large scale TIDs to irregularities of ~10s of km and minutes of periods, in particular those driven by atmospheric acoustic and gravity wave dynamics. The details of data processing methodology are provided the section Steps to Reproduce below, and in (2) and Supporting Information to it. Currently, this archive provides an access to high-resolution visualization of processed vTEC mapped over CONUS for years 01/2017-12/2024. The structure of the archive: /YYYY/MM/DD/animation.mp4, where YYYY - year, MM - month, DD - day of month, animation.mp4 - temporally evolving visualization of processed vTEC (see Steps to Reproduce for the details of data processing methodology).

Explosions along orbits of L1 Lyapunov family. The folder includes the initial conditions of the orbits studied and separated mat files for each explosion. In addition, a JSON file is saved including all the information of the explosions in case of computing simulations outside Matlab. Explosions' files include the state vectors of the fragments for discrete time steps over two years of evolution and classify debris whether fragments escape the system, impact the Earth or the Moon, or continue orbiting throughout the region.
