IRNSS – India’s own GPS – seventh and last of its spacecraft gets placed in orbit

7th IRNSS navsat to be launched next week

India’s own Regional Navigation Satellite System, the IRNSS, is all set to be completed in space next week when the seventh and last of its spacecraft gets placed in orbit.

IRNSS-1G will be launched on April 28
IRNSS will be to the subcontinent what the U.S. Global Positioning System, GPS, is to its users worldwide, but with far greater precision and in Indian control, according to ISRO.
It will drive both everyday uses as a 24/7 standard service for air, sea, ship transport and will also be used for missile-related applications as an encrypted and restricted service.
IRNSS-1G is slated to be launched from the PSLV-C33 from Sriharikota and will be the 35th PSLV flight in the last two decades.
An ISRO official said over the next three to six months, all the IRNSS satellites in the fleet would be stabilised as a constellation, their signals and performance verified and later put to use.
The fleet has two spare satellites ready in case of an emergency, a full-fledged ground control centre in Bengaluru and tracking stations across the country.
The constellation has been in the making since July 2013 when the IRNSS-1A was launched.

Environment Ministry notifies revised standards for Common Effluent Treatment Plants

Environment Ministry notifies revised standards for Common Effluent Treatment Plants (CETPs) Across industrial clusters-PIB CETP • The concept of common effluent treatment plant has been accepted as a solution for collecting, conveying, treating, and disposing of the effluents from the industrial estates. • The effluent include industrial wastewaters and domestic sewage generated from the estate. • This CETP concept helps small and medium scale industries to dispose of their effluents. Otherwise it may not be economical for these industries to treat their wastewaters or there may be space constraints. • Some of these industries may require to give preliminary treatment (for removal of solids) so that the receiving sewers can be maintained free flowing. • It may be required to correct pH or removal of specific pollutant before the industry discharges in CETP. CETP • CETP is designed on the basis of: – Quality and flow rate of the wastewa...
