"GSLV is live into geo space... Real-time data every 30mins"
The referenced post celebrates a launch milestone but conflates the rocket launch vehicle (GSLV) with its operational geostationary payload (such as INSAT-3DS or INSAT-3DR):
- GSLV (Geosynchronous Satellite Launch Vehicle): An expendable 3-stage rocket with cryogenic upper stage that expends all fuel in ~20 minutes to inject a payload into Geosynchronous Transfer Orbit (GTO). The rocket body does not stream Earth observation photos.
- INSAT-3DS / 3DR Payloads: The actual 2,274 kg meteorological spacecraft that use onboard propulsion to circularize at 35,786 km geostationary orbit. It carries optical & infrared imagers designed specifically to scan the entire visible hemispheric disk every 30 minutes.
- International Context: Continuous 30-min geostationary meteorological scanning has been operated globally for decades by the US (GOES), Europe (Meteosat), Japan (Himawari), and China (FengYun). India joined the dedicated GEO meteorological scanning tier with KALPANA-1 (2002) and INSAT-3A/3D series.
