ISRO has successfully launched Its New Remote Sensing Satellite, ‘ RESOURCESAT-2A’, on Wednesday by ISRO’s workhorse Polar Satellite Launch Vehicle from the launch pad at Satish Dhawan Space Centre located at Sriharikota, Andhra Pradesh. RESOURCESAT-2A has been launched with the intentions of Resource Monitoring. This is a follow-on mission to RESOURCESAT-1 and RESOURCESAT-2, which were launched in the year 2003 and year2011 respectively. The main motive of this new launch is to keep going the remote sensing data service to the global users provided by RESOURCESAT-1 and RESOURCESAT-2 by ISRO. ISRO began its 36-hour countdown last night, today said MonoMethyl Hydrazine (MMH) fuel and Mixed Oxides of Nitrogen (MON-3) oxidiser filling operation of the fourth stage (PS4) of PSLV-C36 are completed. PSLV-C36, the 38th flight of PSLV, will place the 1,235kg RESOURSESAT-2A into 817 km polar Sun Synchronous Orbit (SSO).
Information from ISRO, describes that, they have included a high-resolution Linear Imaging Self Scanner (LISS-4) Camera operating in three spectrum bands in near and visible Infrared Region (VNIR), Medium Resolution LISS-3 camera operating three spectral bands in VNIR and another in Short Wave Infrared (SWIR) band and coarse resolution Advanced Wide Field Sensor (AWIFS) camera operating in three spectral bands in VNIR and another in SWIR, with particular spatial resolution. The RESOURSESAT-2A has inbuilt two Solid State Recorders which has 200 Giga Bit each capacity for storing the images captured by its camera and which further can be read out to the ground stations, ISRO added. The weight of the spacecraft is about 1,200kg with a power generation capacity of 1,250 W and a mission life of RESOURCESAT-2A is five years in total.
PSLV-C36, the 38th flight of PSLV, take off at 10:25 hours from the first launch pad at the Satish Dhawan Space Centre in Sriharikota and injected RESOURCESAT-2A into the Orbit in an impeachable flight lasting about 18 minutes. The 1,235kg RESOURCESAT-2A was placed in an 817 km Polar Sun Synchronous Orbit (SSO). The rocket has XL configuration having six additional motors impoverished on to the main rocket. The RESOURCESAT-2A earth observation satellite was the only passenger on the board, with a weight of 1,235 kg. The main reason behind the strategy of not sending any co-passenger on this mission was , the injection altitude is too high for the smaller Nanosat, Microsat and for the Cubesats. The life span of RESOURCESAT-2A is expected to be five years. Launching RESOURCESAT-2A is the ninth successful launch of ISRO, from Satish Dhawan Space Centre, Sriharikota. This entire operation was live telecast on Doordarshan.
ISRO, have made in-house payloads which are there on the board and they are there to test new technologies.To evaluate the performance of the launch operation they have inserted the microelectromechanical sensors. There are numerous new avionics packages on the board, which include an inertial system that is expected to improve the efficiency of future orbital injection operations by ISRO and can also provide an advantage in energy efficiency. This information and the data from this mission will be used in avionics architecture for future ISRO projects.
ISRO has declared it a successful launch of RESOURCESAT-2A by PSLV-C36. The chairman of ISRO A S Kiron Kumar said that this successful launch of RESOURCESAT-2A will provide the continuity to their three tier imaging data, which will be extremely helpful for a variety of applications of Land and Water. “It has been a perfect launch” he added. He also congratulated the entire ISRO team for their extraordinary job they did and putting one more operational satellite into the orbit.
