?GPS Spoofing:

✅GPS spoofing, also known as GPS simulation, refers to the practice of manipulating or tricking a GPS receiver by broadcasting false GPS signals.
✅Essentially, it misleads the GPS receiver into believing it is located somewhere it is not, resulting in the device providing inaccurate location data.
✅This form of cyberattack undermines the reliability of GPS data, which is vital for a variety of applications, from navigation to time synchronization and more.

?How Does GPS Spoofing Work?

✅It exploits the inherent vulnerabilities in the GPS infrastructure – the weak signal strength of GPS satellites.
✅The Global Positioning System (GPS) functions by sending signals from satellites to GPS receivers on Earth.
✅These receivers then calculate their position based on the time it takes for these signals to arrive.
✅However, due to the weak signal strength of the GPS satellites, these signals can be easily overwhelmed by fake signals, resulting in inaccurate location data on the receiving device.
✅Typically, a GPS spoofer begins by acquiring a basic understanding of the victim’s GPS setup, including the types of signals it uses and how they are processed.
✅With that information, the attacker then sends counterfeit GPS signals that mimic the real ones.
✅These fake signals are stronger, causing the receiver to recognize them as authentic signals.
✅As a result, the victim’s GPS receiver ends up processing these counterfeit signals, leading to erroneous location information.

Senior Scientist Rajagopala Chidambaram Passes Away...

Senior scientist and one of the key architects of India’s nuclear programme, Dr. Rajagopala Chidambaram, passed away in the early hours on Saturday at a hospital in Mumbai. He was 88 and had been unwell for several days. Dr. Chidambaram played a pivotal role in shaping India’s nuclear weapons programme. He was instrumental in India’s first nuclear test in 1974, as well as the Pokhran-II tests in 1998, which established India as a nuclear power. He held several key scientific and strategic positions, including Principal Scientific Adviser to the Government of India, Director of the Bhabha Atomic Research Centre, and Chairperson of the Atomic Energy Commission. He was honoured with the Padma Shri in 1975, followed by the Padma Vibhushan in 1999.
Prime Minister Narendra Modi expressed condolences on the demise of Senior Scientist Dr. Rajagopal Chidambaram. In a social media post, Mr. Modi said that the scientist was one of the key architects of India’s nuclear programme. He hailed his contributions in strengthening India’s scientific and strategic capabilities. Mr. Modi also said that he will be remembered with gratitude by the whole nation, and his efforts will inspire generations to come.
