The project falls under the strategic theme “Technology to Enhance Capability of Next Generation Earth Observation Satellites,” a key focus area aimed at advancing Japan’s capabilities in satellite-based environmental monitoring and data-driven climate action.
This selection marks a significant milestone for the consortium, bringing together expertise from space technology, aviation, engineering, and data science to address one of the most pressing global challenges: the accurate monitoring and analysis of carbon dioxide (CO2) emissions and absorption. By leveraging a combination of satellite constellations, aircraft observations, and ground-based sensing technologies, the project seeks to create a comprehensive and scalable system for tracking greenhouse gas emissions with unprecedented precision.
Project Overview and Strategic Vision
The selected project, titled “Source-Specific CO2 Emission and Uptake Monitoring through Satellite Constellation and Aircraft Observations,” will be led by Axelspace Corporation, a recognized innovator in microsatellite development and Earth observation services. The initiative also includes key contributions from Meisei Electric, known for its advanced sensing technologies; ANA HOLDINGS, which will provide aviation-based observation capabilities; and JIJ Inc., a company specializing in data analytics and optimization technologies.
The project is funded under JAXA’s Space Strategy Fund, a program designed to accelerate the development of cutting-edge space technologies that can contribute to both national priorities and global sustainability goals. The fund supports innovative projects that have the potential to transform how satellite data is collected, analyzed, and utilized across industries.
At its core, the consortium’s vision is to establish a next-generation Earth observation system that integrates multiple layers of data collection. Upon completion, the project aims to deploy a new satellite constellation working in coordination with aircraft-based sensors and ground-based observation systems. This integrated approach will enable simultaneous, multi-point data acquisition across different times of the day—specifically morning, noon, and afternoon—allowing for a more dynamic and granular understanding of CO2 emissions and absorption patterns.
Advancing CO2 Monitoring Capabilities
One of the defining features of this initiative is its focus on source-specific CO2 monitoring. Traditional satellite-based observation systems often provide broad, aggregated data that can be useful for identifying general trends but lack the resolution needed to pinpoint emissions at the sector or source level. This project aims to bridge that gap by enabling detailed analysis of emissions based on specific sectors, time intervals, and geographic locations.
The ability to differentiate between emissions sources—such as industrial facilities, transportation networks, and urban infrastructure—represents a major advancement in environmental monitoring. By combining high-frequency satellite observations with targeted aircraft measurements and ground-based data, the system will generate a comprehensive dataset that can be used to identify emission hotspots, track changes over time, and evaluate the effectiveness of mitigation strategies.
This level of detail is expected to play a crucial role in supporting climate policy and regulatory frameworks. Governments, organizations, and international bodies will be able to rely on objective, transparent, and high-resolution data to assess progress toward greenhouse gas reduction targets and to design more effective policies.
Building an Integrated Observation Ecosystem
The project’s integrated observation model is designed to overcome the limitations of standalone systems. Satellite constellations provide broad coverage but may have limited temporal resolution depending on orbital constraints. Aircraft-based observations, on the other hand, can offer targeted and flexible data collection but are not suitable for continuous global monitoring. Ground-based sensors provide highly accurate local measurements but lack wide-area coverage.
By combining these three observation modalities, the consortium aims to create a synergistic system that leverages the strengths of each platform. Satellites will provide continuous, wide-area monitoring; aircraft will conduct validation and targeted measurements; and ground-based sensors will ensure data accuracy and calibration.
This multi-layered approach is particularly valuable in urban environments, where emissions are highly dynamic and influenced by a variety of factors such as traffic patterns, industrial activity, and energy consumption. The ability to capture data at multiple times of the day will provide insights into diurnal variations in emissions and absorption, offering a more complete picture of carbon dynamics.
Technological Innovation: Compact Spectrometers
A key technological component of the project is the development of a new generation of compact spectrometers. Spectrometers are essential tools for measuring gas concentrations in the atmosphere, as they analyze how different gases absorb light at specific wavelengths. By measuring the degree of light absorption, these instruments can accurately determine the concentration of gases such as CO2.
Conventional high-precision spectrometers used in government-operated satellites are typically large, complex, and expensive. These limitations have restricted their deployment to a small number of high-cost missions, limiting the frequency and coverage of observations.
To address this challenge, the consortium will focus on miniaturizing spectrometer technology while maintaining high levels of accuracy and reliability. The new compact sensors will incorporate advanced detector technologies developed domestically in Japan, enabling significant reductions in size, weight, and cost.
This innovation will make it feasible to deploy spectrometers across a larger number of platforms, including small satellites, aircraft, and ground-based systems. The result will be a more scalable and cost-effective observation network capable of delivering high-resolution data on a global scale.
Development Roadmap and Testing Phases
The project will follow a structured development roadmap that includes design, prototyping, testing, and deployment phases. One of the critical steps in this process will be the validation of the newly developed compact sensors through aircraft-based testing.
These validation tests will allow the consortium to assess the performance of the sensors under real-world conditions, ensuring that they meet the required standards for accuracy and reliability. Aircraft-based observations will also provide an opportunity to compare sensor data with existing measurement systems, helping to refine calibration methods and improve data quality.
Following successful validation, the consortium plans to launch a demonstration satellite equipped with the compact spectrometer. This satellite is expected to be deployed between fiscal years 2030 and 2032. The in-orbit demonstration will serve as a proof of concept, providing valuable data that will inform the design and deployment of the full satellite constellation.
Enabling Global Climate Action
Beyond its technological advancements, the project has significant implications for global climate action. Accurate and transparent data on CO2 emissions and absorption is essential for tracking progress toward international climate goals, such as those outlined in the Paris Agreement.
By providing high-resolution, source-specific data, the system developed under this project could serve as a foundation for an international benchmark for greenhouse gas reductions. Such a benchmark would enable countries and organizations to compare their performance, identify best practices, and implement more effective mitigation strategies.
Moreover, the availability of reliable data could support the development of new economic mechanisms for emissions reduction, such as carbon pricing and emissions trading systems. By linking emissions data to financial incentives, policymakers can encourage more sustainable practices across industries.

The success of this project relies on the combined expertise of its participating organizations. Axelspace brings extensive experience in satellite development and Earth observation services, while Meisei Electric contributes advanced sensing technologies. ANA HOLDINGS provides aviation capabilities that are essential for airborne observations, and JIJ Inc. offers expertise in data analysis and optimization.
This collaborative approach reflects a broader trend in the space industry, where partnerships between private companies, government agencies, and research institutions are driving innovation and accelerating the development of new technologies.
The project is also expected to have a positive impact on Japan’s space industry, تعزيزing its position as a leader in Earth observation and environmental monitoring. By developing cost-effective and scalable technologies, the initiative could open up new opportunities for commercial applications, including environmental consulting, urban planning, and energy management.
As the project moves forward, the consortium will continue to refine its technologies and expand its capabilities. The successful deployment of the demonstration satellite will mark a critical milestone, paving the way for the full-scale implementation of the satellite constellation and integrated observation system.
In the long term, the project has the potential to transform how we monitor and understand carbon emissions on a global scale. By combining cutting-edge technology with a collaborative, multi-platform approach, Axelspace and its partners are helping to build a more transparent and data-driven framework for addressing climate change.
