Scientists who measure the \u00a0position of the Earth\u00a0 in the universe with \u00a0millimeter precision\u00a0 have been grappling with a growing problem over the years. The \u00a0exponential increase in wireless traffic\u00a0\u2014from WiFi connections to satellite Internet and mobile data networks\u2014is interfering with astronomical observations<\/a> that are vital for accurately locating our planet in the cosmos. This issue is not just a quirky anomaly; without precise measurements, everyday services like \u00a0GPS\u00a0, online banking, and global supply chains could face significant disruptions.<\/p>\n <\/p>\n To ensure that \u00a0satellites function correctly\u00a0, we need to know their exact positions at all times. This task hinges on geodesy<\/a>, a science that establishes precise reference frameworks utilizing \u00a0astronomical objects\u00a0 as anchor points. The most stable and distant reference points we know of are \u00a0supermassive black holes\u00a0 located in the centers of distant galaxies. As these black holes consume stars and gas, they emit radiation jets that radio telescopes can detect through a technique known as \u00a0very long base interferometry\u00a0.<\/p>\n <\/p>\n Radiotelescopes require specific frequencies from the radioelectric spectrum<\/a> to capture weak signals from deep space effectively. For decades, this ‘traffic’ was scarce, allowing scientists to utilize bands not exclusively reserved for astronomy. However, this situation has changed drastically. With six generations of mobile telecommunications, the rise of powerful WiFi networks, and a growing number of satellites beaming the Internet directly to Earth, the spectrum is now saturated. Terrestrial signals have become so intense that they obstruct geodesic observatories, rendering them unable to ‘see’ through the noise.<\/p>\n <\/p>\n The “global geodetic supply chain<\/a>” underpins modern technological infrastructure. Without precise measurements of the Earth’s position, satellite navigation systems would lose accuracy, electrical networks might go offline, and international trade could face severe disruption. Hence, the importance of radio telescopes and other technologies designed for precise measurements cannot be overstated; their continued functionality is pivotal for the work of geodesists and the service of modern society.<\/p>\n <\/p>\n Geodesists are advocating for the release of more frequencies dedicated to astronomy<\/a> within the radio spectrum. Achieving this requires international treaties to be revised during global conferences. Ideas such as establishing \u00a0radio-silence zones\u00a0 around key telescopes, as well as agreements with satellite operators to minimize emissions, are being explored. A well-known example is the community of Green Bank<\/a>, which prohibits mobile networks due to existing civil and military radio needs.<\/p>\n <\/p>\n Any viable solution must be global, given that geodetic measurements rely on interconnected telescopes situated across all \u00a0continents\u00a0. However, the initial step toward finding a resolution is cultivating awareness of this pressing issue.<\/p>\n <\/p>\nGeodesy: The Science of Earth Positioning<\/h2>\n
