According to reports, my country's first remote sensing satellite designed specifically to obtain ocean salinity information, the Ocean Salinity Detection Satellite (also known as Haiyang 4-01), has successfully completed all on-orbit test missions and has reached the standard of being delivered to users and used for a long time. As an important part of the national civil space infrastructure, the satellite was successfully launched on November 14, 2024.
Since the satellite was successfully put into orbit, it has undergone rigorous assessments at multiple key stages, including platform working status setting, payload startup testing, satellite-ground link establishment, and business function verification. After a series of tests, all functions and performance of the satellite have met or exceeded the design index requirements.
The successful launch of the ocean salinity detection satellite not only improves my country's existing ocean satellite observation system, but also fills my country's gaps in the field of spaceborne ocean salinity detection. It can be called an important milestone in the development of my country's ocean satellites.
In the future, this satellite will shoulder the important task of providing global high-precision ocean salinity data for the fields of marine environmental protection, disaster prevention and mitigation, and global climate change research, and provide solid technical support for the implementation of my country's maritime power strategy.
In addition, the satellite also has the function of soil moisture measurement, which can meet the application needs of users in multiple industries such as drought monitoring, agricultural area environmental monitoring, and numerical weather forecasting, demonstrating its broad application prospects and practical value.
