ISRO- New success: NovaSAR, S1-4 & PSLV- C42

Sep16, 2018. PSLV-C42 successfully launches two foreign satellite from Satish Dhawan Space Centre (SDSC). The Polar Satellite Launch Vehicle (PSLV) was programmed to put NovaSAR & S1-4 in orbit, that is 583 km above the surface.
NovaSAR has the ability to take pictures of the surface of the Earth in every kind of weather, day or night. The spacecraft will assume a number of roles like forest mapping, land use & ice cover monitoring, flood & disaster monitoring but its designers specifically want to see if it can help monitor suspicious shipping activity.
S1-4 is a high-resolution Optical Earth Observation Satellite, used for surveying resources, environment monitoring, urban management and for the disaster monitoring. This spacecraft will discern objects on the ground as small as 87cm across.
Both S1-4 & NovaSAR were manufactured by Surrey Satellite Technology Limited of Guildford.

UK engineers have long had expertise in space radar but their technology has previously always gone on broader missions, such as those for the European Space Agency. NovaSAR, which has the distinctive shape of a cheese grater, is uniquely British. However, Its radar instrument was developed for SSTL by Airbus in Portsmouth. The mission incorporates low-cost, miniaturised components and will aim to demonstrate a more affordable approach to radar imaging. It will operate in a number of modes for applications that include the detection of oil spills, flood and forestry monitoring, disaster response, and crop assessment. But perhaps its most interesting role will be in maritime observation.

Low-cost was the first priority from the start of this project & ISRO did a great job at launching these 889 kgs payload (Together NovaSAR & S1-4) successfully with the help of its versatile PSLV-C42.
