<h5>Which satellite has been launched by ISRO?</h5><p>On 29th May 2023, the Indian Space Research Organisation (ISRO) successfully launched the NVS-01 navigation satellite. This satellite was launched from the Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh. The satellite weighs 2,232 kg.</p><p>This satellite will help India's regional navigation system to provide accurate navigation. ISRO head Sreedhara Panicker Somanath said the satellite had been successfully placed in orbit. NVS-01 is the first among a series of five satellites planned to be launched by ISRO.</p><p>The NVS-01 is a part of the Navigation with Indian Constellation (NavIC) satellites designed to improve India's navigation capabilities.</p><div class="raw-html-embed"><figure> <video width="100%" controls=""> <source src="https://firebasestorage.googleapis.com/v0/b/newsahoot.appspot.com/o/isro-successfully-launches-a-new-satellite%2FNVS%2001%20LAunch.mp4?alt=media&amp;token=dfe6705b-82a8-4d6d-b3f9-6bea6c8afc82&amp;_gl=1*1q64ufh*_ga*MTIzNjQ0ODg2NS4xNjgzNzk5MjMy*_ga_CW55HF8NVT*MTY4NTUyODcyMy4xMy4xLjE2ODU1Mjk3MjcuMC4wLjA." type="video/mp4"> </video> <figcaption>Launch video of the NVS-01 satellite.

This service is provided using Global Positioning System (GPS). It is a system for sending signals from satellites to a particular device that can show the location of a person or thing on the Earth's surface. GPS is a free service provided using a network of satellites in orbit.</p><p>The United States government controls these satellites. NavIC has been developed by ISRO. They are a group of satellites placed in orbit that communicate with various ground stations. This helps provide navigation services to both Indian civilians and the military forces.</p><h5>Why was NavIC developed?</h5><p>NavIC is India's GPS replacement. It was developed as the country required better navigation in the aviation sector. NavIC covers India and an area of around 1500 kilometres beyond the Indian border. The signals are intended to give users greater locational accuracy.</p><p>NavIC's use is currently limited. It is used to provide emergency warning alerts to fishermen heading into areas of the sea where network connectivity is unavailable and to track and provide information about natural disasters. Some smartphones have NavIC support, but it will take time to fully enable it across the country for everyone.</p><p>Let’s hope that we can start using Indian developed satellite navigation system soon.</p><h5>How does satellite navigation work?</h5><div class="raw-html-embed"><figure> <iframe width="100%" height="350" src="https://www.youtube.com/embed/RSA3feQ9gKk" title="How does GPS work?" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen=""></iframe><figcaption>A video telling us how GPS works. Video by NASA Space Place.</figcaption></figure></div><p>Satellite navigation systems such as GPS help us determine where we are and how to navigate to various locations. This system has three parts: satellites, a receiver (similar to a GPS device or a smartphone), and specific signals sent out by the satellites.</p><p>These satellites are constantly orbiting the Earth. They have highly accurate clocks attached to them and continuously send out signals. The receiver connects to the GPS device, such as a smartphone and picks up the satellite signals.</p><p>Each satellite sends a signal that shows its location and the time it was sent out. The receiver measures the time it takes for satellite signals to reach it. Once the receiver finds the distance between itself and at least four satellites, it determines its accurate location on Earth. After determining this location, the information is displayed on a map.</p><p>This is how we get to know where we are on a map on our smartphones. Pretty cool, right?
