The Global Navigation Satellite System, such as GPS, experiences failures due to ground based signal interference, or jamming. NASA’s Soil Moisture Active Passive satellite reads in a frequency that records these jamming events, whether intentional or unintentional. Taking data from 5-10 May 2025, I developed a code that converts the data to a map showing high interference regions, compared them to real-world events, and developed a structure to describe these areas when comparing them to each other. Mapping data grouped from 5-7 May and 8-10 May shows connections to real world events, typically military action and potential space weather events. Smaller areas could be the result of unknown events, leading to further research. Refining the structure with more areas of interest improves the accuracy of the information, allowing this tool to become more accessible. Results are a repeatable process to analyze interference events, and can be utilized to measure and record space weather effects on earth.
