It is a problem for the entire PL

Scientists who measure the position of the earth in the universe with a millimeter precision have been experiencing a growing problem in their measurements for years. The exponential increase in wireless traffic, which goes from WiFi connections to the Internet by satellite and mobile data network, is interfering with astronomical observations that allow to locate our planet in the cosmos. This is not turkey mucus, because without these measurements, everyday services such as GPS, online banking or global supply chains could collapse.

Black holes measurements. For satellites to work properly, we need to know exactly where they are at every moment. This task depends on Geodesya science that establishes precise reference frameworks using astronomical objects such as anchor points. The most stable and distant we know are the Supermasive black holes located in the distant galaxies center. When stars and gas devour, they emit radiation jets that radio telescopes can detect by means of a technique called Interferometry very long base.

An increasingly saturated network. Radiolescopes need specific frequencies of the Radioelectric spectrum To capture these weak signals from deep space. For decades, this “traffic” was scarce and scientists could use bands not reserved exclusively for astronomy. But the situation has changed dramatically. Six generations of mobile telephony, increasingly powerful wifi networks and thousands of satellites sending the Internet The spectrum has satiated directly to Earth. Terrestrial signals are now so intense that they prevent geodesic observatories “see” through them.

Collapse. The “global geodetic supply chain“Sustains modern technological infrastructure. Without precise measurements of the earth’s position, satellite navigation systems They would lose accuracyelectrical networks could be unconpired and international trade would be compromised. Hence the importance of radio telescopes and the rest of precise measurement technologies can continue to function without problems thanks to the work of geodesists.

Release more frequencies. The geodesists They claim more frequencies Dedicated to astronomy within the radio spectrum, and for this international treaties must be reviewed in world conferences. Solutions such as radio silence areas are also studied around essential telescopes and agreements with satellite operators to prevent their emissions from these instruments. An example is The people of Green Bankwhich prohibits mobile networks because there are civil and military radio.

Any solution must be global, since geodetic measurements require connected telescopes from all continents. The first step, however, is to become aware of the problem.
