Indian Space Research Organization (ISRO) will launch its next satellite on August 31.
ISRO said it would put into orbit the IRNSS-1H satellite at 18:59 hours on Thursday, Aug. 31, 2017, using the rocket PSLV-C39 from Sriharikota. The payload would augment the capacity of India’s seven-satellite ‘NavIC’ constellation or the GPS equivalent in space.
The NavIC constellation consists of 3 IRNSS satellites located in suitable orbital slots in the geostationary orbit and the remaining 4 in geosynchronous orbits with the required inclination and equatorial crossings in two different planes. Configured identially, all the seven satellites are equipped with I-1K Bus to be compatible on-board the ISRO workhorse PSLV vehicle.
The first satellite in the series, IRNSS-1A developed a technical snag earlier, as its rubidium atomic clock failed in space, requiring the current satellite, which will take over the mantle of the first payload in the series.
IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. An Extended Service Area lies between primary service area and area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East.
IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) which is provided to all the users and Restricted Service (RS), which is an encrypted service provided only to the authorised users. The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area.
Some applications of IRNSS:
- Terrestrial, Aerial and Marine Navigation
- Disaster Management
- Vehicle tracking and fleet management
- Integration with mobile phones
- Precise Timing
- Mapping and Geodetic data capture
- Terrestrial navigation aid for hikers and travellers
- Visual and voice navigation for drivers
