GSAT-6


Indian Space Research Organization (ISRO) has successfully positioned India’s latest communication satellite GSAT-6 into its orbital slot. It was positioned in its orbital slot 83 Degree east after carrying out four drift arresting maneuvers. It has been collocated with other four communication satellites INSAT-4A, IRNSS1C, GSAT 12 and GSAT 10. About GSAT-6 satellite GSAT-6 satellite was carrying S-Band and C-Band transponders meant for public and strategic purposes. It weighs 2117 kg and has mission life of nine years. The satellite is having S-Band Unfurlable Antenna (UFA) of 6 m diameter. This is the largest antenna ever made by ISRO for a satellite. This antenna is utilized for five spot beams over the Indian mainland to exploit the frequency reuse scheme and to increase frequency spectrum utilization efficiency in India. GSAT-6 is the 25th geostationary communication satellite of India and 12th in the GSAT series. Application: It will provide S-band multimedia communication and broadcasting services across the country. C-Band is for strategic purpose and it will provide national security and law enforcement agencies a secured satellite telephony services. Background ISRO had successfully launched GSAT-6 from an indigenous cryogenic engine GSLV-D6 rocket from Sriharikota on 27 August 2015. ISRO had performed successive orbit raising operation of the satellite and had deployed the UFA successfully after the launch.

South Asian Association on Regional Cooperation


Disaster Mitigation conference of member counties of South Asian Association on Regional Cooperation (SAARC) has begun in New Delhi on 3 September 2015. The two day conference seeks to chalk out and undertake various joint efforts on various issues related to disaster mapping and mitigation in the member nations. Key facts The conference is being held by keeping in mind the prevalent geo-climatic conditions as well as increased frequency of natural disaster and calamities in the SAARC region. It is also being held in the wake of the recent Nepal earthquake (April 2015). It calls for enhanced levels of preparedness and risk resilience amongst member countries. It also seeks collaborative action amongst member countries to deal jointly and individually in disaster situations and ensure minimal loss of lives and property. South Asian Annual Disaster Management Exercise (SAADMEx) India has taken the lead to begin SAADMEx, a simulation exercises on disaster management in the region. In this regard, India has requested all SAARC countries to participate in this exercise. SAADMEx aims at augmenting current levels of individual and joint preparedness of member countries in the rescue, relief and response operations during disaster situations. The exercise will be conducted in two phases. First phase is the current coordination conference which will discuss the requirements and modalities of the main exercise. Second phase will cover the main exercise which will be held from November 23-26, 2015 in New Delhi. Three components of second phase of SAADMEx are Table Top Exercise (TTx) Field Training Exercise (FTx) and After Action Review (AAR).
