He is serving as the Director of Dhirubhai Ambani Institute of Information and Communication Technology in Gandhinagar,Gujarat,India. Prior to joining DA-IICT,he served as the Director of Indian Institute of Space Science and Technology,Thiruvananthapuram. Dasgupta also served as the Deputy Director,Space Applications Centre,Ahmedabad and the Director of the Development and Educational Communication Unit of Indian Space Research Organisation.
Oceansat-1 or IRS-P4 was the first Indian satellite built primarily for ocean applications. It was a part of the Indian Remote Sensing Programme satellite series. The satellite carried an Ocean Colour Monitor (OCM) and a Multi-frequency Scanning Microwave Radiometer (MSMR) for oceanographic studies. Oceansat-1 thus vastly augment the IRS satellite system of Indian Space Research Organisation (ISRO) comprising four satellites,IRS-1B,IRS-1C,IRS-P3 and IRS-1D and extend remote sensing applications to several newer areas.
The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO to co-develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite. The satellite will be the first radar imaging satellite to use dual frequencies. It will be used for remote sensing,to observe and understand natural processes on Earth. For example,its left-facing instruments will study the Antarctic cryosphere. With a total cost estimated at US$1.5 billion,NISAR is likely to be the world's most expensive Earth-imaging satellite.
Nilamber Pant is an Indian space scientist,a former member of the Space Commission of India and a pioneer of satellite based communication and broadcasting in India. He served at the Satish Dhawan Space Centre and the ISRO Satellite Centre before becoming the vice chairman of the Indian Space Research Organization (ISRO). The Government of India awarded him the fourth highest Indian civilian honour of Padma Shri in 1984.
ScatSat-1 was a satellite providing weather forecasting,cyclone prediction,and tracking services to India. It has been developed by ISRO Satellite Centre,Bangalore whereas its payload was developed by Space Applications Centre,Ahmedabad. The satellite carries a Ku-band scatterometer similar to the Oceansat-2 which became dysfunctional after its life span of four-and-a-half years. India was dependent on NASA's ISS-RapidScat for prediction of cyclone forecasting and weather prediction. The data generated by this mini-satellite are used by National Aeronautics and Space Administration (NASA),European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and National Oceanic and Atmospheric Administration (NOAA).
EOS-04 or Earth Observation Satellite - 04 is an Indian Space Research Organisation Radar Imaging Satellite designed to provide high-quality images under all weather conditions for applications such as Agriculture,Forestry &Plantations,Soil Moisture &Hydrology and Flood mapping. It is a follow on to RISAT-1 satellite with similar configuration. The satellite is developed by the ISRO and it is the sixth in a series of RISAT satellites.
