Satellite Programme: Indian National Satellite - 3
Programme details
Programme description
Series of six operational satellites in geostationary orbit, only three (INSAT-3 A, D. D-prime) equipped with meteorological instruments.
Developed and operated by ISRO for the Indian Meteorological Department (IMD).
3-axis stabilised platforms.
The design life time of the satellites is 7 years.
The primary position of the flight units with meteorological instrument is 83°E.
The replacement policy is based on placing further satellites on 93.5°E and 74°E.
Data circulation
CDAS (Command and Data Acquisition Station) for real-time acquisition of the full information through different streams for different instruments.
MDD (Meteorological Data Dissemination) for selected data through a communication satellite (INSAT-3C).
CWDS (Cyclone Warning Dissemination System), activated during the cyclone season, for selected data through a communication satellite (INSAT-3C).
HRIT (High Rate Information Transmission) (with INSAT-3D) for near-real time broadcasting of full resolution images and data.
LRIT (Low Rate Information Transmission) (with INSAT-3D) for broadcasting of image frames and other data.
DCS (Data Collection Service) to relay messages from self-timed DCP (Data Collection Platform).
SASAR (Satellite Aided Search And Rescue) to relay emergency signals to Local User Terminals (LUT).
