Bringing Atmospheric Data Down to Earth | Mapping the Ionosphere with Android Devices

The Ionosphere impacts things you use every day, like GPS, other location-based services, and even radio communications. This episode of Field Notes will discuss what the Ionosphere is, why it matters so much for navigation, and how Google is crowdsourcing measurements from Android phones to map it accurately on a global scale. You’ll hear from: Dr. Jade Morton, Professor of Aerospace Engineering Sciences, University of Colorado, Boulder Brian Williams, PhD, Senior Staff Engineer, Google Research Resources: Learn more about mapping the ionosphere → https://goo.gle/3UIqAjy Watch more Field Notes → https://goo.gle/FieldNotes Subscribe to the Google Research Channel → https://goo.gle/GoogleResearch How can Android devices be used to map the Ionosphere? This research project delves into how Android phones are being utilized as a scientific instrument to create more accurate and detailed maps of the Ionosphere, a critical part of Earth's upper atmosphere. Changing concentrations of charged particles that make up the ionosphere affect the transmission of radio waves that enable radio communications, including GPS systems. That’s why accurately mapping the ionosphere is so crucial for industries that rely on GPS, such as aviation, emergency response, and agriculture. Privacy protections ensure that no individual device can be identified. Our ionosphere maps are created using aggregated, de-identified measurements of the radio signals between satellites and the receivers in Android devices. These measurements come from a subset of Android devices that already have location and relevant settings enabled and that are using satellite signals to determine location.You can read more about how Android uses this data in our privacy policy (https://goo.gle/location-data). While scientific monitoring stations provide more precise ionosphere measurements than what we get from phones, combining measurements from many phones over a large area reduces the noise and can extend coverage to locations with few or no monitoring stations. The enhanced ability to map the ionosphere could lead to improved GPS accuracy, as well as a more comprehensive understanding of the ionosphere's structure and behavior. What are the benefits? We are actively working to translate these technological improvements into better location accuracy. Our goal is for Android users to be equipped with even better location-based services for navigation and maps, ride-sharing, and other apps that benefit from precision location. The impact of this research extends beyond personal device use; better understanding the ionosphere can shed light on and perhaps help better predict space weather events, such as solar storms, helping to prevent disruption to our critical global communication systems and unlock opportunities in emergency response, aviation, and agriculture. Overall, this research highlights the growing role of Android technology in advancing our understanding of the Ionosphere and enhancing the performance of GPS and other location-based services.
