ISRO’s navigation satellite NVS-03 to be launched today:During 1999 Kargil War, US did not help India, so India built its own indigenous GPS

ISRO is set to launch its navigation satellite NVS-03 tonight at 11:51 p.m. The satellite will be launched under the NavIC mission aboard a GSLV-F18 rocket from Sriharikota in Andhra Pradesh.NavIC stands for Navigation with Indian Constellation. It is India’s own regional satellite navigation system, developed by ISRO. The need to develop NavIC was felt after the Kargil war in 1999. At the time, India had sought location-related information on the military area from the US GPS, but the US refused. India then developed its own indigenous GPS. Question: What is the NVS-03 satellite? Answer: NVS-03 is the third satellite in India’s second-generation NavIC satellite series. It has been developed to strengthen NavIC services and add new technological features. Question: How many NavIC satellites have been launched so far? Answer: According to information available as of 30 October, 11 satellites have been launched for NavIC. One launch was unsuccessful, while one satellite was unable to provide navigation services due to a technical problem. NVS-03 is scheduled to be launched on the night of 30 October. Question: What is special about NVS-03? Answer: It uses indigenous atomic clock technology. It will be capable of providing services on the L1, L5 and S bands. The addition of the L1 band could help increase the number of devices that support NavIC. Question: How will NavIC benefit ordinary people? Question: Will NavIC replace GPS? Answer: No. GPS works across the world, while NavIC is limited to an area extending up to 1,500 km around India. Both systems can work together. NavIC is not intended to replace GPS, but to reduce India’s dependence on foreign systems. Question: Will NavIC work on every mobile phone? Answer: No. The mobile phone must have hardware support for NavIC and the relevant frequency bands. This feature is not available on all smartphones. Mobile phones that support NavIC can use its signals along with GPS.
