Recently 'ISRO System for Safe and Sustainable Space Operations Management' Compiled by (IS4OM) 'Indian Space Situational Assessment Report' (ISSAR) 2023 Has been issued.
Key findings of the report
global perspective
- Space object number trend: This report indicates a steady increase in the number of 'space objects' in space. According to the data received, the maximum number of payloads has been launched into the Earth's orbit in the year 2023.
- This is a sign of improved access to space and increasingly diverse applications of space technology in daily life.
- A total of 3,143 space objects were sent into space with the help of 212 launches and on-orbit in the year 2023, compared to 2,533 space objects through 179 launches in the year 2022.
- Need for Space Traffic Management: The increasing number of active satellites requires STMs to operate in environments.
- There is currently no universally accepted framework available for STM, unlike air and maritime traffic, so various activities between two active satellites are resolved by 'inter-operator' coordination.
indian landscape
- Important points in India's satellite launch: of private and educational institutions from the beginning of Indian space travel till December 31, 2023. Total 127 Indian satellites including satellites have been projected.
- Indian Space Mission: Apart from all these launches, three important Indian space missions (Chandrayaan-2 orbiter, Aditya-L1 and propulsion model of Chandrayaan-3) were also active by the end of the year 2023.
- Launch of Indian satellites: A total of 21 Indian satellites have been re-launched into the atmosphere by the end of 2023. For example, Megha-Tropics-1 was controlled and re-launched through a very challenging medium.
- Rocket: Total from Indian launch vehicles 82 rocket Was placed in orbit by the year 2023.
- ISRO's successful launches: All seven launches of ISRO in the year 2023 were successful.
- These launches include SSLV-D2/EOS7, LVM3-M3/ONEWEB_II, PSLV-C55/TeLEOS-2, GSLV-F12 NVS-01, LVM3-M4/Chandrayaan-3, PSLV-C56/ DS-SAR, and PSLV-C57. /Aditya L-1.
Space Object Proximity Analysis (SOPA) for satellites
- Introduction: ISRO regularly predicts the movements of other space objects for Indian space activities through analysis by the Indian Space Research Centre, IS4OM/ISTRAC.
- Collision Avoidance Maneuvers (Collision Avoidance Manoeuvres- CAM): In case of any critical approach, CAM is used to protect the spacecraft.
- closer approach and The number of CAMs executed by ISRO is also currently the highest. Is.
the way forward
- Development of space sector will be encouraged for sustainable space activities, which requires adopting a holistic approach.
- Unlike terrestrial activities, any activity in space has potentially global and far-reaching effects and Near Earth space is a limited resource which should be used responsibly for social benefit.
