NVS-01

• ISRO has recently launched a new satellite NVS-01.
• NVS-01 is first of the India’s second-generation satellites envisaged for NavIC (Navigation by Indian Constellation) services.
• It is built by ISRO’s UR Rao Satellite Centre in Bengaluru.
• NVS-01, weighing 2,232 kg satellite – heaviest in constellation, was launched using Geosynchronous Satellite Launch Vehicle (GSLV) rocket.
• For the first time, an indigenously developed Rubidium atomic clock is flown in NVS-01 to provide accurate locations.
• It has a mission life of over 12 years, longer than 10-year life of first-generation (existing) satellites.
• This series incorporates L1 band signals additionally which increases interoperability with other satellite-based navigation systems.

ABOUT NAVIC

• NavIC, earlier known as Indian Regional Navigation Satellite System (IRNSS), is designed with constellation of seven satellites.
• Three satellites are placed in geostationary orbit and four satellites are placed in inclined geosynchronous orbit.
• At present, India uses its NavIC series of satellites for civilian (Standard Position Service) and defence navigation (Restricted Service) in the Indian mainland and 1500 kms beyond India’s borders.
• These two services are provided in both L5 and S band.
• The system is used in terrestrial, aerial, marine transportation, location-based services, personal mobility, resource monitoring, surveying and geodesy, scientific research
