Naraespace announced on the 23rd that its methane monitoring satellite 'NarSha' was officially listed on the 'Greenhouse Gas Satellite Missions Portal' under the Committee on Earth Observation Satellites (CEOS).
Narsha is a constellation of 25kg-class small satellites, developed to meet the growing demand for methane monitoring by providing repeated observations over a wide area. This satellite model will also be used in two methane monitoring satellites being developed as part of the Gyeonggi Climate Satellite Project.
With this listing, Narsha joins the world's leading greenhouse gas observation satellite missions on the official CEOS portal. This portal also includes climate observation satellites from various governments, including NASA's OCO-2 and JAXA's GOSAT-2.
Founded in 1984, CEOS is an international satellite consortium comprised of approximately 60 organizations worldwide, including the European Space Agency. It spearheads the standardization and shared use of satellite data and operates an international cooperation system to address the climate crisis.
Most greenhouse gas observation satellites listed on the CEOS portal are government-led projects. Narasa Space is the first Korean private company to register a methane monitoring satellite. Notably, Narsha passed CEOS's preliminary review and was listed despite being a "planned mission" satellite that had not yet been launched. This is interpreted as meaning that it met international standards in terms of technical feasibility and data transparency.
Through this listing, Narsha's mission design, observation plan, and data utilization methods will be made public through CEOS. The data produced will be utilized in various climate response projects, including establishing carbon neutrality policies and monitoring implementation of the Paris Agreement.
Professor Jeong Su-jong of Seoul National University, who advised on the CEOS registration process, evaluated the significance of the official incorporation of a Korean private greenhouse gas satellite into the global monitoring system.
Kim Geuk-nam, head of the system integration team at Naraspace, said that the hyperspectral payload, micro-satellite system, methane production algorithm, and data utilization method were evaluated as being in line with the purpose of responding to the climate crisis.
