Sriharikota (Andhra Pradesh). The Indian Space Research Organization (ISRO) on Monday successfully launched the second generation navigation satellite NVS-01 using a Geostationary Satellite Launch Vehicle (GSLV).
NVS-01 will strengthen the country’s regional navigation system and provide accurate and real-time navigation services.The 27.5-hour countdown for the 51.7 meter tall three-stage GSLV rocket lifted off from the second launch pad of the Sriharikota Space Center here, about 130 km from Chennai. Launched when it happens. It took off for the target at 10.42 am in clear sky at the scheduled time.
This second generation navigation satellite series is considered to be an important launch as it will ensure continuity of NAVIC (India’s indigenous navigation system like GPS) services and the satellite will provide real-time position and information over an area of ​​about 1,500 km around India and the mainland. Will provide timely services.
ISRO said that the NavIC has been designed in such a way that with the help of signals, the position of the user can be obtained within a radius of 20 meters and accurate information of time in an interval of 50 nanoseconds. Congratulating the entire team for the “excellent result”, he told the Mission Control Center after the launch, “NVS-01 was precisely placed in its orbit by GSLV. Congratulations to the entire ISRO team for making this mission possible.
Referring to the anomaly that occurred in the launch vehicle’s cryogenic stage in August 2021, he said today’s success comes after the “failure” of GSLV F10. He expressed happiness that “improvements in the cryogenic stage and The lessons learned have really paid off”. He gave the credit of solving the problem to the ‘Failure Analysis Committee’.
Somnath said that NVS-01 is a second generation satellite, which has many additional capabilities. He said that the signals received from it would be more secure and civilian frequency bands have been made available in it. It is one of the five such satellites. 20 minutes after launch, the rocket placed the 2,232 kg NVS-01 navigation satellite into Geostationary Transfer Orbit (GTO) at an altitude of about 251 km. NVS-01 with Carried L1, L5 and S band equipment. The second generation satellite will also have an indigenously developed rubidium atomic clock.
ISRO said this is the first time an indigenously developed rubidium atomic clock was used in Monday’s launch. According to the space agency, scientists earlier used imported rubidium atomic clocks to determine the date and location. Now, the satellite will have a rubidium atomic clock developed by the Space Applications Center in Ahmedabad. It is a critical technology that only a few countries have. ISRO has developed the NAVIC system to meet the requirements of position, navigational and timing information, especially in relation to the civil aviation sector and military requirements. NAVIC was earlier known as Indian Regional Navigation Satellite System (IRNSS).
