Tianwen 1 successfully failed: it used the domestically developed Kirin operating system
The tianwen 1 lander, which recently landed on Mars, used China’s homegrown Kirin operating system. During the Chang ‘e-3 mission, the Kylin team faced unprecedented extreme challenges due to the strict requirements on the stability and real-time performance of the operating system. More than 180 problems were documented during the mission. Among these problems, the kylin team is the most headache: the aerospace side proposed that the real-time response accuracy of the operating system is 8 milliseconds, while the real-time accuracy of the general purpose system can reach 20 milliseconds to 30 milliseconds at most. More than 180 problems were eventually resolved before chang ‘e-3 was launched.

Aurora Unified Messaging System UMS new version online! Multidimensional statistical analysis drives operational growth
Operation is a bridge connecting users and products. For all operators, they have a common ultimate goal: to improve transformation, reduce costs and maximize push effects. However, the excellent push operation is not a simple “accumulation” push of multiple message channels, but through the integration of channels, users, content and other aspects, the independent push is integrated into a whole, so as to produce synergistic effect, reduce internal friction, save operating costs, and finally achieve the operation effect of 1+1 > 2. Because of this, unified message push is increasingly favored by enterprises.
Recently, Aurora, a leading developer service provider in China, officially released UMS 2.0, a unified messaging system. The new version adds support for more third-party channels, message sending methods, message sending policies and security auditing mechanisms on the basis of the original intelligent management of multiple message channels. The most important thing is to add more dimensions of statistical analysis to help operators understand the laws and values behind the data, thus boosting the improvement of operation results.
