Abstract

Global Positioning System (GPS) satellites orbit earth and store positional information that is relayed to receivers on earth. Disruptions in the signal can result in changes in the amplitude and phase of the radio waves. These disruptions can be a result of an atmospheric phenomena known as scintillation, which is caused by plasma particles in the atmosphere interacting with the waves. An accurate position of the receivers is required to analyze the scintillation data and how plasma affects radio signals.

This project calculates and plots definitive location solutions of six ASTRA Connected Autonomous Space Environment Sensor (CASES) receivers in Alaska in the Geographic Coordinate System (latitude- longitude) format. The positions were determined by computing the mean of navigation solution data stored by the receivers. IIT’s Apollo server was used to extract the data files, which stored the navigation solution data in three-dimensional cartesian space, and run the MATLAB computation codes. Latitude- Longitude positions were obtained after converting the position solutions computed in three-dimensional space.
