The Indian Space Research Organisation (ISRO) is in the headlines again. Today ISRO has achieved a great feat in the satellite launch system. ISRO successfully launched cartosat-2 series satellite along with 19 other foreign satellites from Sriharikota, Andhra Pradesh, today at 9:25 am. The co-passenger satellites were from Indonesia(1), USA(13) Canada (2) and Germany(1). Apart from these foreign satellites, 2 co-passengers were from Indian Universities.
Cartosat-2 – The Primary Satellite
The Cartosat-2 series satellite is the primary satellite carried by PSLV-C 34. It is similar to the earlier Cartosat 2, 2A and 2B. After its injection into the 505 Km Polar Sun Synchronous orbit by PSLV-C34, the satellite will be brought to operational configuration following which it will begin to provide regular remote sensing services using panchromatic and multispectral cameras.
The imagery sent by the satellite will be useful in cartographic applications, utility management like road network monitoring, water distribution and creation of land use maps. The satellite has a mass of 727.5 Kg and is powered by solar arrays generating 986 watts and two Li- Ion batteries. The design life of the satellite is 5 years.
LAPAN – A3 is a 120 Kg Indonesian microsatellite for Earth observation for land use, Natural Resource and environment monitoring.
BIROS is a small scientific satellite from the German Aerospace Center. The main objective is the remote sensing of high temperature events.
The satellite’s main objective is the study of Automatic Identification System (AIS) from low-earth orbit.
Dove Satellites (USA)
The Planet Labs’ Dove Satellites are Earth imaging satellites. A total of 12 Dove Satellites were carried in this mission inside the 3 QuadPack dispensers.
An Earth Observation Satellite meant to study the concentration of greenhouse gases (carbon dioxide and methane)
The imaging satellite that will be able to capture sub meter resolution imagery and HD video.
Besides these international satellites, PSLV-C34 also carried two University satellites, 1 Kg SWAYAM from College of Engineering, Pune and 1.5 kg SATHYABAMASAT from SATHYABAMA University, Chennai.
The total weight of all the satellites is 1,288 Kg. This is the 35th consecutive successful launch of ISRO. The PSLV-C34 launch of 20 satellites has made a significant impact on ISRO’s ability to launch multiple satellites in a single launch.
