    Pecora 21/ISRSE 38 Organized Special Presentation (SP) Sessions When submitting an abstract for a proposed special session, please include the session ID (e.g. SP1, SP2) as a Keyword. SP1 Open Data Cube: A new data technology for enhancing the use of satellite data to address sustainable development goals Brian Killough, NASA The Open Data Cube (ODC), created and facilitated by the Committee on Earth Observation Satellites (CEOS), is an open source software architecture that allows analysis-ready satellite data to be packaged in "cubes" to minimize data preparation complexity and take advantage of modern computing for increased value and impact of Earth observation data. This session will summarize the ODC progress, discuss the advancements of country-based implementation and present the status of several new open source ODC applications and their potential to address society and the UN Sustainable Development Goals. SP2 An overview of the current Analysis Ready Data products, tools, applications and impacts Andreia Siqueira, Geoscience Australia Public and private agencies have been committed to address the big data challenge by producing Analysis Ready Data products (ARD) for their users. The ARD products are enabling users to get first hand satellite data that are ready to use for a wide range of applications, including time-series analysis and the way forward to multi-sensor interoperability. The Analysis Ready Data session has as its main objective to present the current state of knowledge on global efforts towards producing Analysis Ready Data (ARD). It is expected that topics across the maturity of ARD products, including validation and calibration, the overall CEOS Analysis Ready Data for Land (CARD4L) framework as well as the Product Family Specifications (PFS) and the Product Alignment Assessment process (PAA) will be presented and discussed.

    International Journal of Advanced Science and Technology Vol. 29, No. 6s, (2020), pp. 232-236 An Analytical Search for Efficient Microcontroller-On Board Computer for Veltech-NanoSat 1Prabhu Kumar Surarapu, 2Tumuluri Sree Sravya, 3D.Ruthra Prabha 1Assistant professor, 2,3UG student Department of ECE Veltech Rangarajan Dr.Sagunthala R&D Institute of Science and Technology, Chennai Abstract On Board Computer (OBC) isthe heart of the satellites and particularly, It is the main subsystem in the Nano satellite.OBC is responsible for communication, data storage and functional control between all subsystems in the satellite. Right Choice of micro controller is very important task since complete monitoring of the subsystems depends on the OBC. The probability of the success of the satellite mission depends on the reliability of microcontroller and components. In this paper we have listed down, compared and analysed the microcontrollers that were used earlier in nanosatellites and pico satellites like PRATHAM, JUGNU, SATYABAMASAT, ICUBESAT,STUDSAT and SWAYAM. Key words--- On Board Computer (OBC), Microcontroller, VeltechNanoSat, Nano satellite I. INTRODUCTION Veltech-NanoSat, the first satellite initiative of Veltech group of institutions, Chennai, Tamilnadu,India, is in the process of development at Veltech Rangarajan Dr.Sagunthala R&D Institute of Science and Technology under guidance of Indian Space Research Organisation (ISRO) . This project was initiated with the purpose enabling the students and faculty who are involved with design, analysis and testing. The important mission of this nano satellite is to monitor the agricultural fields, land sliding, forest fire, flow and quantity of water. Like other satellites Veltech-NanoSat has also various subsystems which include Payload, Power, Communication, Attitude control, Structure, Mechanisms, Thermal and On Board Computer (OBC).

  • ISRO Launches EMISAT Satellite
    ISRO Launches EMISAT Satellite drishtiias.com/printpdf/isro-launches-emisat-satellite The Indian Space Research Organisation (ISRO) has launched the EMISAT satellite on onboard the PSLV-C45 from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The Polar Satellite Launch Vehicle (PSLV) was also carrying 28 international nanosatellites — 24 from the US, two from Lithuania and one each from Spain and Switzerland. The flight of PSLV was also the longest mission of the PSLV, lasting around three hours. EMISAT Satellite The EMISAT satellite is aimed at electromagnetic spectrum measurement. It is an electronic intelligence satellite for the Defence Research and Development Organisation (DRDO). About Satellite Mass: 436 kg Manufacturer: ISRO Orbit Type: Sun-synchronous Polar orbit(SSPO) Altitude: About 753 km. Polar Orbit A polar orbit travels north-south over the poles and takes approximately 90 minutes for a full revolution. These orbits have an inclination near 90 degrees. This allows the satellite to see virtually every part of the Earth as the Earth rotates underneath it. An orbit is called sun-synchronous when the angle between the line joining the center of the Earth and the satellite and the Sun is constant throughout the orbit.] Purpose of Satellite 1/2 EMISAT is an all weather and all terrain condition satellite, which will allow it to work through clouds, rain, forest and coastal areas. EMISAT is an ELINT (Electronic Intelligence) satellite, which means it will have a radar to measure the electromagnetic spectrum - so as to intercept and analyze radar signals, find their location, identify the hostile radars based on their radio frequency (RF) signature.
