- Abstract
&Presently many high resolution Satellites from different countries are in use for various applications like mapping, infrastructure planning and development, agriculture assessment, environmental monitoring and other strategic areas. Further many advanced remote sensing satellites are also being developed to meet the ever increasing requirements of Land Information systems (LIS) and Geographical Information Systems (GIS), Navigation and Disaster Management Systems (DMS) requirements. In order to meet these ever increasing vide variety of requirements, conventional single Satellite System may not effectively serve the purpose. Hence a constellation of Satellites with various types of sensors like high resolution electro optical imaging with Panchromatic, Multispectral (MS) and Hyper spectral (HS) and Infrared (IR) bands and Radar Imaging based satellites operating in GEO and LEO Orbits, to provide large amount imageries with best resolution in the centimeter range and with best quality and the maximum coverage of any area over the globe within the shortest possible time of any event or with the maximum frequency of revisit shall meet all the future requirements. The use of small, highly agile platform adoptable to many types of payloads and direct data transmission and dissemination to the actual users via the use of mobile platforms and via the available links is the key driver for the Advanced Remote Sensing Satellites. This series of Satellites will have a design life of more than 10 years taking into account the launch vehicle injection dispersions and multiple satellites launched by the single launch vehicle. These Satellites will have the capabilities like simultaneous real-time imaging, and transmission and onboard storage and transmission at a later time at a reduced data rate meeting the X or Ka Band RF high bit rate Data Transmission system requirements. Many advanced coding, compression and encryption techniques are also applied to meet the various requirements of the users. These Advanced Satellites will be using the state of the art technologies in the key areas that drive the image quality and the geometric accuracy requirements. These satellites constellation will be realizable and operational in 3 to 5 years time frame.
