It’s because technologies like GPS have limitations. For instance, GPS does not provide pointing direction. Satellite signals can be jammed or masked, and it is difficult to get GPS signals underwater.\u003c/p\u003e\n\u003cp\u003eEarth’s magnetic field provides an all-weather referencing system. Magnetic navigation is based on the Earth’s magnetic field and is a safe and reliable form of navigation that can be used in the air, on land and sea and even underwater. Scientists already use observatories, satellites and ship and airborne surveys to keep track of changes in the Earth’s magnetic field for magnetic navigation purposes.\u003c/p\u003e\n\u003cp\u003eHowever there are gaps in the coverage—both in time and space—and scientists are always looking for alternative ways to obtain geomagnetic data.\u003c/p\u003e\n\u003cdiv class=\"image image-right image-right-legacy\"\u003e\n  \u003cimg\n    src=\"https://s3.amazonaws.com/digitalgov/_legacy-img/2015/01/250-x-444-Crowd-Mag-iTunes-app-map.jpg\"\n    alt=\"250-x-444-Crowd-Mag-iTunes-app-map\"/\u003e\u003c/div\u003e\n\n\u003cp\u003eThis is precisely where you, citizen scientist, come in armed with the CrowdMag app on your smartphone.\u003c/p\u003e\n\u003cp\u003eSmartphones have what’s called a magnetometer, which tracks the strength of the earth’s magnetic field at a point in space. It does more, but that’s the unscientific explanation.\u003c/p\u003e\n\u003cp\u003eThrough the CrowdMag app, phones all around the world send magnetometer data to NOAA researchers, who then combine the crowdsourced magnetic data with real-time solar wind data to create near real-time models of Earth’s time changing magnetic field. The data also helps map local magnetic noise sources (think power transformers and iron pipes) to improve accuracy of magnetic navigation systems.\u003c/p\u003e\n\u003cp\u003eCan digital magnetometers built in modern mobile smartphones be used as scientific instruments? That’s what this project will help NOAA scientists explore. So be part of the crowd and download the CrowdMag app. Just open the app and grant permission to share your magnetic data with NOAA, it’s that simple to start using your smartphone in the name of science. Check out the app’s crowdsourced map to see data collected from the phones of citizen scientists like you from around the world.\u003c/p\u003e\n\u003cp\u003eSuccess of this mission ultimately depends on you, and many others just like you.\u003c/p\u003e\n\u003cp\u003eCrowdMag is available \u003ca href=\"https://play.google.com/store/apps/details?id=gov.noaa.ngdc.wmm2\"\u003eon Google Play\u003c/a\u003e for Android devices, and Apple’s \u003ca href=\"https://itunes.apple.com/app/id910578825\"\u003eiTunes store\u003c/a\u003e for iOS devices.
