November 29: PSLV 43 HysIS and 30 customer satellites
- ISRO Polar Satellite Launch Vehicle (PSLV-C43) on Thursday successfully launched 31 satellites from Satish Dhawan Space Centre (SDSC) in Sriharikota.
- The PSLV-C43 lifted off at 9:57:30 (IST) from the First Launch Pad and injected India’s Hyper-Spectral Imaging Satellite (HysIS) into the 645 km sun-synchronous polar orbit, 17 minutes and 19 seconds after the lift-off.
- Later, 30 foreign satellites were injected into their intended orbit after restarting the vehicles fourth stage engines twice.
- HysIS is an earth observation satellite built around ISRO’s Mini Satellite-2 (IMS-2) bus weighing about 380kg. The mission life of the satellite is five years.
- The primary goal of HysIS is to study the earth’s surface in both the visible, near infrared and shortwave infrared regions of the electromagnetic spectrum. Data from the satellite will be used for a wide range of applications including agriculture, forestry, soil/geological environments, coastal zones and inland waters, etc.
- HysIS had the company of one micro and 29 nano-satellites from eight countries, including Australia (1), Canada (1), Columbia (1), Finland (1), Malaysia (1), Netherlands (1), Spain (1) and USA (23). The total weight of these satellites was about 261.50 kg. Satellites from Australia, Columbia, Malaysia and Spain were flown aboard PSLV for the first time. These foreign satellites launched are part of commercial arrangements between Antrix Corporation Limited and customers.
November 14: GSLV MKIII –D2 launches GSAT29
- India’s GSAT-29 communication satellite was successfully launched by the second developmental flight of Geosynchronous Satellite Launch Vehicle MarkIII (GSLV MkIII-D2) on Wednesday from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.
- GSAT-29 is a multiband, multi-beam communication satellite, intended to serve as test bed for several new and critical technologies. Its Ku-band and Ka-band payloads are configured to cater to the communication requirements of users including those from remote areas especially from Jammu & Kashmir and North-Eastern regions of India.
September 16: PSLV- C42 launches 2 foreign satellite
- PSLV-C42 of ISRO successfully launched two satellites — NovaSAR and S1-4 — from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota here.
- The satellites belong to UK-based Surrey Satellite Technology Limited (SSTL), which has a contract with Antrix Corporation Ltd, the commercial arm of ISRO.
- NovaSAR carries S-band Synthetic Aperture Radar (SAR) and an Automatic Identification Receiver payloads. The satellite applications include forestry mapping, land use and ice cover monitoring, flood and disaster monitoring and maritime missions. It will be operated from SSTL’s Spacecraft Operations Centre in Guildford, UK.
- S1-4 is a high resolution earth observation satellite meant for surveying resources, environment monitoring, urban management and disaster monitoring.
April 12: PSLV-C41 launches IRNSS-1I
- In its forty third flight, ISRO’s PSLV-C41 successfully launched the 1425 kg IRNSS-1I Navigation Satellite from Satish Dhawan Space Centre SHAR, Sriharikota.
- IRNSS-1I is the latest member of the ‘Navigation with Indian Constellation (NavIC)’ system. NavIC, also known as Indian Regional Navigation Satellite System (IRNSS), is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland.
March 29: GSLV launches GSAT-6A Satellite
- India’s Geosynchronous Satellite Launch Vehicle (GSLV-F08) successfully launched GSAT-6A Satellite into Geosynchronous Transfer Orbit (GTO).
- Today’s launch of GSLV was its twelfth and took place from the Second Launch Pad at Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, the spaceport of India.
- GSAT-6A is a communication satellite built by ISRO to provide mobile communication services through multi beam coverage. For this, it is equipped with S and C band transponders.
January 12: PSLV launches 31 Satellites in a Single Flight
- ISRO’s Polar Satellite Launch Vehicle, in its forty second flight, successfully launched the 710 kg Cartosat-2 Series Remote Sensing Satellite for earth observation along with 30 co-passenger satellites from Satish Dhawan Space Centre SHAR, Sriharikota. This flight is designated as PSLV-C40.
- Microsat is a small satellite in the 100 kg class that derives its heritage from IMS-1 bus. This is a technology demonstrator and the fore runner for future satellites of this series.
- Indian Nano Satellite-1C is another Indian co-passenger payload of PSLV-C40. It is the third satellite in the Indian Nanosatellite series. The first two satellites of this series were carried as co-passenger payloads by PSLV-C37 in February 2017. INS-1C will be carrying Miniature Multispectral Technology Demonstration (MMX-TD) Payload from Space Applications Centre (SAC). Data sent by this camera can be utilised for topographical mapping, vegetation monitoring, aerosol scattering studies and cloud studies.
- The 11 kg INS-1C and and the 100 kg class Microsat, the two Indian co-passenger satellites of Cartosat-2, are also being monitored and controlled from ISTRAC, Bengaluru. The 28 international customer satellites belong to Canada, Finland, France, Republic of Korea, UK and the USA.
