And now since a few days, we also have Insat-3C leaving 74.0°E, drifting East 0.5°/day.Insat-4CR still drifting West 0.7°/day, near 61°E now.These slow drift speeds are more typical for relocation than for end-of-life manoevring.After some further reading, I understand Gsat-18 is intended to replace both 3C and 4CR.Gsat-18 is at 74.0°E since 21 Oct 2016. So very recently, services must have switched to Gsat-18.Anyone knows more?Leaves me wondering what the smaller Gsat-14 is doing now, backup capacity?
After INSAT-4CR was moved to a new orbital slot a few months ago, its efficiency has been improved and a little extra capacity created for select use, he said.
INSAT-3C stayed at 93.5°E until July 18, since then the orbit was raised 3 times.Now near 16°E, drifting 3.5° W per day.I think this was the end-of-life manoeuver, can anyone give confirmation?
GOVERNMENT OF INDIA MINISTRY OF SPACE LOK SABHAUNSTARRED QUESTION NO: 1824ANSWERED ON: 26.07.2017Indigenous SatellitesKAPIL MORESHWAR PATILRAOSAHEB PATIL DANVEWill the PRIME MINISTER be pleased to state:(a) the details of satellites being operated by the country at present;(b) whether the Government is seeking foreign aid/cooperation for operating these satellites and if so, the amount of fund spent for operation of foreign satellites each year;(c) the extent to which indigenous satellites are being used; and(d) the modalities worked out by the Government for developing indigenous satellites in the country?ANSWER MINISTER OF STATE IN THE MINISTRY OF PERSONNEL, PG & PENSIONS AND IN THE PRIME MINISTER’S OFFICE(DR. JITENDRA SINGH):(a) At present, there are 42 Indian satellites operational in orbit comprising of:i. Fifteen Communication Satellites namely, INSAT-4A, 4B & 4CR, GSAT-6, 7, 8, 9, 10, 12, 14, 15, 16, 17, 18 & 19. ii. Fourteen Earth Observation Satellites namely, Resourcesat-1, 2 & 2A, RISAT-2, Cartosat-1, Cartosat-2, Cartosat-2 Series (5 Nos.), Oceansat-2, SARAL & SCATSAT-1. iii. Four Meteorological Satellites namely, Kalpana-1, INSAT-3D& 3DR and Megha-Tropiques.iv. Seven Navigational Satellites namely, IRNSS-1A, 1B, 1C, 1D, 1E, 1F & 1G.v. Two Space Science Satellites namely, Mars Orbiter Mission & Astrosat.(b) No, Madam. Government is not seeking any foreign aid/ cooperation for operating these satellites. Indian Space Research Organisation (ISRO) is not operating any foreign satellites.(c) The currently operational indigenous satellites are being utilised to support various applications and services in the area of resource monitoring, weather forecasting, telecommunication, broadcasting, disaster management, location based services, including host of societal applications.(d) ISRO has been developing satellites indigenously since 1975. Except the first generation INSAT satellites, all communication satellites have been built indigenously. All the earth observation, meteorological, navigation and space science satellites have been developed indigenously by ISRO.
