The current Earth observation and remote sensing satellites have orbited the Earth in a network like manner, and the amount of data generated has also increased by TB or even PB. Geographic information and satellite remote sensing data are important and non renewable information resources, and many data require rapid processing and permanent storage. Faced with these massive and increasingly increasing amounts of data, how to build a high-performance storage system with large capacity, high stability, and scalability is a key issue that needs to be considered.
Beijing Aerospace Yuxing Technology Co., Ltd. is headquartered in Beijing and has established more than ten branch offices in Xi'an, Zhengzhou, Zhongwei, Qitaihe, Jinghe, South Pacific, Africa, South America and other places. It is the first comprehensive solution provider in China to integrate commercial aerospace testing and operation control technology research and development, aerospace communication product manufacturing, and spacecraft in orbit operation and management services.
At present, a global satellite ground station network and commercial remote sensing satellite calibration field, including more than 60 ground stations, have been established, leading the domestic commercial aerospace measurement and operation control field.
Solution
This time, Yuxing Aerospace has chosen the Xinyun satellite remote sensing geographic mapping image storage solution to provide users with safer and more reliable satellite remote sensing data services, ensuring the security and integrity of data, and further promoting the widespread application and development of satellite remote sensing technology in various fields.
The common application scenario requirements for geographic information and satellite remote sensing data storage are as follows.
a. High speed collection and reading of satellite data
In the face of the challenge of high-speed data acquisition and processing, space satellites have chosen Xinyun storage as their powerful backing. Xinyun Storage, with its single device read bandwidth of up to 8000MB/s and write bandwidth of 3400MB/s, easily meets the stringent requirements of image data storage and data processing high transmission.
Of particular note, Xinyun RDMA's direct and fast read technology achieves direct data transmission between the user layer and hardware by bypassing the kernel and reducing memory copies. This not only significantly improves transmission bandwidth, but also significantly reduces latency, providing a more efficient and reliable solution for space satellite data processing.
In addition, Xinyun Storage's massive storage capacity can support up to 1320TB of storage space on a single machine, and is equipped with 2 SAS expansion interfaces, supporting expansion to 3960TB, fully meeting the growing data storage needs of space satellites.
b. Efficient application of fast copy technology
When space satellites face the challenge of massive image data storage and processing, adopting Xinyun direct connection ultra high speed DAS storage or Xinyun unified storage has become a wise choice.
Xinyun Storage not only provides excellent performance, but also achieves efficient data transfer between central storage and intermediate storage, intermediate storage and target storage through its unique fast copy technology. This technology significantly shortens data transmission time, thereby significantly accelerating the speed of space satellite data processing and effectively optimizing project cycles.
c. Building an efficient data center data center
Space satellites have achieved significant optimization and improvement in data storage and management through the use of Xinyun unified storage or Xinyun distributed storage. This storage solution not only supports centralized data storage, but also allows multiple machines to share and manage data resources uniformly, greatly improving the efficiency and convenience of data processing.
With the rapid growth of space satellite image data, the capacity and performance of Xinyun storage can be linearly expanded, ensuring that the storage system can always cope with the growing storage needs. This flexibility and scalability enable space satellites to efficiently and stably process massive image data, providing strong support for scientific research, monitoring, and decision-making.
Xinyun is a leading manufacturer of domestic enterprise level video, audio and image storage. Xinyun's geographic information and satellite remote sensing data storage solutions are widely used in many industrial customers, such as the Aerospace Academy, Changguang Satellite, Aerospace Hongtu, National Survey and Mapping, Guoyao Xintiandi, Zhongnong Sunshine, Hunan Satellite Guide, and so on.
