CON­STEL­LA­TION OF SATEL­LITES

SP's Aviation - - SPACE -

IRNSS-1G is the last of the seven satel­lites con­sti­tut­ing the space seg­ment of the IRNSS. IRNSS-1A, 1B, 1C, ID, IE and 1F, the first six satel­lites of the con­stel­la­tion, were suc­cess­fully launched by PSLV on July 2, 2013, April 4, 2014, Oc­to­ber 16, 2014, March 28, 2015, Jan­uary 20, 2016 and March 10, 2016, re­spec­tively. All the six satel­lites are func­tion­ing sat­is­fac­to­rily from their des­ig­nated or­bital po­si­tions.

IRNSS is an in­de­pen­dent re­gional nav­i­ga­tion satel­lite sys­tem de­signed to pro­vide po­si­tion in­for­ma­tion in the In­dian re­gion and 1,500 km around the In­dian main­land. IRNSS pro­vides two types of ser­vices, namely, Stan­dard Po­si­tion­ing Ser­vices (SPS) — pro­vided to all users and Re­stricted Ser­vices (RS) — pro­vided to au­tho­rised users. A num­ber of ground fa­cil­i­ties re­spon­si­ble for satel­lite rang­ing and mon­i­tor­ing, gen­er­a­tion and trans­mis­sion of nav­i­ga­tion pa­ram­e­ters, etc., have been es­tab­lished in 18 lo­ca­tions across the coun­try.

The Min­is­ter for the De­part­ment of Space, Ji­ten­dra Singh, said that the coun­try also plans to launch a com­mu­ni­ca­tions satel­lite that will pro­vide en­hanced band­width con­nec­tiv­ity to ru­ral ar­eas. The satel­lite will be launched to­wards the end of 2016 or the first quar­ter of 2017. ISRO plans to launch 22 satel­lites in an­other flight of PSLV in­clud­ing 19 satel­lites from four coun­tries: 13 from the US, three from Ger­many, two from Canada and one from In­done­sia.
