README <br> <strong>1. Introduction</strong> <br> <br> <strong>1.1</strong> This folder contains time series for the elevation angle obtained from simulations for the following orbit altitudes: <br> 1. 1000 km 2. 1200 km 3. 1400 km 4. 1600 km 5. 1800 km 6. 2000 km <br> <br> <strong>1.2</strong> For each altitude, the following orbit inclinations where considered: <br> 20º, 25º, 30º, ..., 85º <strong>1.3 </strong>The elevation angle time series were observed from 16 Earth Station's, ES's. Those ES's are numbered and located* as follows: <br> 1. ES1 = ( 0º, 276.7121º) 2. ES2 = ( 5º, 276.7121º) 3. ES3 = (10º, 276.7121º) 4. ES4 = (15º, 276.7121º) 5. ES5 = (20º, 276.7121º) 6. ES6 = (25º, 261.7121º) 7. ES1 = (30º, 259.7121º) 8. ES2 = (35º, 259.7121º) 9. ES3 = (40º, 259.7121º) 10. ES4 = (45º, 259.7121º) 11. ES5 = (50º, 259.7121º) 12. ES6 = (55º, 259.7121º) 13. ES7 = (60º, 259.7121º) 14. ES8 = (65º, 259.7121º) 15. ES9 = (70º, 259.7121º) 16. ES10 = (75º, 259.7121º) 17. ES11 = (80º, 259.7121º) 18. ES12 = (85º, 259.7121º) <br> *Location for the ES's is provided in cartesian format: (latitude in deg, longitude in deg) <strong>1.4</strong> The eccentricity for all the simulations correspond to that of a circular orbit. <br> <br> <strong>1.5</strong> For organization convenience, all the time series files are organized within six folders according to their orbit altitudes. <br> <br> <strong>1.6</strong> Files in this folder are provided to facilitate reproduction of our work and to encourage future work based on our proposed methodology and results. <br> <br> <br> <br> <br> <br> <strong>2. General description</strong> <br> <br> <strong>2.1</strong> Time series filenames Each time series is identified with the following character format: <br> "hhhh-ii-ES#.csv". where: hhhh indicates the orbit altitude ii indicates the orbit inclination ES# indicates the ES from which the elevation angle is being observed <br> <br> <strong>2.2</strong> Time series length Elevation angle time series are provided for a simulation period of 180 days. <br> <br> <br> <br> <br> <br> <strong>3. File format</strong> <br> <strong>3.1</strong> Time series are provided using the .csv (comma separated values) file format to facilitate reading through diverse programming tools. <br> <strong>3.2</strong> Each time series is provided as an individual two-column .csv file. The first column contains the time vector and the second contains the corresponding elevation angle vector. <br>
