ISRO to Launch Navigation Satellite: All You Need To Know | AIB

The Indian space agency ISRO will launch its eighth navigation satellite IRNSS-1H today from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The 29-hour countdown for today’s launch has started on Wednesday at 14:00 hrs IST. 

The satellite, which is intended to be a replacement for IRNSS-1A, after its atomic clocks on board had failed. The atomic clocks are vital for providing exact locational data, and every satellite has three such clocks. IRNSS-1H navigation satellite will be carried by the PSLV-C39 rocket that will lift-off at about 7 pm today.

The launch will open a new episode in the country’s history of space research as, for the first time, the private sector has been actively involved in assembling and testing of a satellite supervised by ISRO.

Indian Regional Navigation Satellite System (IRNSS) is meant to provide accurate real-time positioning and timing services to users in India as well as the region stretching up to 1,500 km from its boundary. It is an independent regional navigation satellite system developed by India on par with US-based GPS.

This system will offer services like terrestrial and marine navigation, disaster management, vehicle tracking and fleet management, navigation aide for hikers and travelers, visual and voice navigation for drivers, was named ‘NavIC’ (Navigation with Indian Constellation) by Prime Minister Narendra Modi.

NavIC is useful for fishermen to reach the potential fishing area. They can also get alert messages about inclement weather conditions, high waves or when they approach international maritime boundary line. These services are provided through a software application on a smartphone. The Indian space agency said NavIC helps drivers to cross distances and also enable transport operators to track their vehicles and it is also useful for search and rescue operations.

NavIC provides two types of services – standard positioning service and restricted service. Standard positioning service is meant for all users and encrypted service which is provided only to authorized users like military and security agencies.
