Will DIGIPIN replace PIN codes? India's new digital address system explained- how it works and all you need to know
The Department of Posts has introduced DIGIPIN, a digital addressing system designed to provide accurate location identification. It was developed in collaboration with IIT Hyderabad and the National Remote Sensing Centre of ISRO. DIGIPIN, or Digital Postal Index Number, is a unique 10-digit code that shows the exact location of a property, unlike PIN codes, which cover large areas. This number is an open-source, interoperable, geo-coded, grid-based digital address system. DIGIPIN system divides India into nearly 4m x 4m grids, assigning each grid a distinct 10-character alphanumeric code derived from its latitude and longitude coordinates. DIGIPIN aligns with the vision of the Department of Posts to provide Address-as-a-Service (AaaS), which is a range of services related to address data management to support users, government entities, and private sector organisations, according to an official release on May 27, 2025. To acquire a DIGIPIN, users must visit the 'Know Your DIGIPIN' portal at and locate their residence, and create the code. To accurately determine DIGIPIN, users will require a device with a Global Navigation Satellite System (GNSS) facility to find their exact location as per latitude and longitude. This is converted into a DIGIPIN code. The Department of Post is developing an application for users to access DIGIPIN. Additionally, the programming code for DIGIPIN will be shared in the public domain for fetching and decoding the DIGIPIN. Unlike a traditional postal code or PIN code, which identifies broader areas, a DIGIPIN points to a specific 4m x 4m location. This ensures accurate geolocation, location, according to the Department of Posts. No. According to the Department of Posts, DIGIPIN will not replace traditional addresses; rather, it will provide an extra digital layer of precision without replacing existing postal addresses. DIGIPIN only requires the latitude and longitude of the location, and no personal data is associated with it. The code solely represents a location, and no individual's information is recorded.

Japanese study unveils how earthquakes quietly disrupt satellites and communications
Source: Reuters While earthquakes have been traditionally linked to surface-level destruction, new findings show that their effect goes far beyond the crust of the Earth reaching into the upper atmosphere and even interfering with space-based technologies. In a pioneering piece of research, scientists from Nagoya University have been able to develop the first-ever 3D visualisation of atmospheric disturbances in the ionosphere resulting from a significant earthquake. With data from Japan's extensive network of more than 4,500 Global Navigation Satellite System (GNSS) receivers, the scientists charted the ripple of the 7.5-magnitude Noto Peninsula Earthquake on January 1, 2024. What they found, reported in the journal Earth, Planets and Space , not only deepens the knowledge of earthquakes travelling through the atmosphere but also poses serious issues of satellite vulnerability and communication. 3D imaging reveals how earthquakes disrupt the ionosphere The ionosphere is a highly charged atmosphere of Earth between 60 and 1,000 kilometres high that plays a critical role in global communications by bending and slowing down radio waves from satellites. Earthquakes, as it happens, can perturb this sensitive layer by creating acoustic waves that propagate upward from the surface. To observe these disturbances, scientists tracked delays in GNSS satellite signals induced by changes in the electron density of the ionosphere. By using tomography methods, as in medical CT scans, they imaged the dynamic 3D behaviour of the ionosphere in response to the seismic shockwaves. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo About ten minutes following the earthquake, wave-like ripples that are similar to those patterns created in concentric circles when a stone is thrown into water started to emanate in the ionosphere. These ripples, also referred to as seismo-ionospheric perturbations, showed unexpected tilts in their structures that were not included in previous models. New insights reveal earthquakes don't emit waves from a single source Earlier science reference models had long considered that the waves created by a quake have a single point source. The 3D visualizations presented in this study told a different story. The waves were not coming from one but rather from several rupture points along a 150-kilometre fault. Dr. Weizheng Fu, lead author, said earthquakes release energy not from a point source but evolve gradually along fault lines. The researchers' new model took this dynamic rupture process into account by modeling wave emissions from sections of the fault in time intervals of some 30 seconds. This new method successfully replicated the angled sound wave patterns observed in the ionosphere. This change in comprehension greatly enhances our potential to forecast and make sense of the atmospheric influence of immense seismic occurrences. Study warns of seismic effects on navigation and communication tools The potential of this research extends far beyond scientific understanding. Ionospheric disturbances have the potential to degrade the precision of GPS systems, to slow down satellite communications, and to affect navigation tools—concerns which are of the utmost importance during disaster relief and aviation. Co-author Professor Yuichi Otsuka highlighted the wider technological significance of the research. "By knowing how these waves are created and how they change, we can start to predict and buffer risks in communication systems before and after earthquakes," he explained. In addition to increasing technological resilience, the research also opens the door to better earthquake early warning systems . Historically dependent on ground-based sensors, the systems could be greatly enhanced by the inclusion of atmospheric data, specifically patterns seen in the ionosphere.

Shockwaves in space: Earthquakes found to shake up satellite signals
When the Earth shakes, the impact doesn't stop at the surface. New research reveals that powerful earthquakes can send shockwaves all the way into space, disrupting satellite signals and GPS systems by disturbing the charged upper layers of our atmosphere. Scientists from Nagoya University in Japan have made the first 3D visualisation of how the atmosphere reacted to a powerful 7.5-magnitude earthquake that hit the Noto Peninsula on 1 January 2024. They used data from over 4,500 Global Navigation Satellite System (GNSS) receivers across Japan. Their research, published in the journal Earth, Planets and Space, shows how earthquakes can send complex sound waves into the upper atmosphere, disturbing a layer called the ionosphere. These disturbances can affect satellite communications and GPS signals, and challenge what scientists previously believed about how these waves travel. What is the Ionosphere, and why does it matter? The ionosphere is a part of the atmosphere that lies 60 to 1,000 kilometres above the Earth. It's filled with charged particles and plays an important role in sending radio signals from satellites to the ground. When the earthquake happened, it created sound waves that travelled upward into the ionosphere. These waves changed the amount of charged particles, which slowed down satellite signals. By measuring the delays in these signals, the researchers were able to calculate these changes and use a technique similar to a medical CT scan to build 3D images of the disturbances. Surprising patterns in the sky About 10 minutes after the earthquake, wave-like ripples appeared in the ionosphere, similar to the way water ripples after a stone is dropped in a pond. However, the team noticed something unusual – some of the waves tilted in a strange direction, south of the earthquake's epicentre, and slowly straightened out as they rose higher. Old models, which assumed that these waves came from a single point, couldn't explain this pattern. The breakthrough came when the scientists considered that the earthquake didn't rupture in one spot, but along a 150-kilometre fault line. Dr Weizheng Fu, the lead author, said, 'Earthquakes don't rupture at one point, but spread along faults.' Their updated model showed that the sound waves were created at different places along the fault, around 30 seconds apart. This matched what they observed in the sky. Why does this matter for technology and safety? These atmospheric changes can interfere with GPS systems and satellite signals, which are used in everything from smartphones to aeroplanes. Co-author Professor Yuichi Otsuka said, 'Understanding these patterns can help reduce the risk of technology failures during earthquakes.' The research could also help improve earthquake early warning systems. By watching for these atmospheric waves as well as ground movements, scientists may be able to give faster and more accurate alerts. Looking ahead: Applying the model to other natural disasters The team now plans to use this method to study how volcanic eruptions, tsunamis, and severe weather affect the ionosphere. This could improve how we prepare for disasters and monitor them in real time. By studying how earthquakes leave their mark in the sky, this research helps protect important systems and gives us a better understanding of how Earth and space are connected.
