According to Zhao Junsuo, similar to the “Android” concept in the mobile phone system, it has a good openness and is equipped with a special integrated platform for development, operation and maintenance, which can be quickly iterated and continuously evolved, thereby continuously improving the intelligence level of satellites in orbit.

This system greatly reduces the “threshold” for satellite applications to be uploaded to space for testing: satellite applications only need to be uploaded to the system, and the satellite attitude can be automatically adjusted according to the shooting task, and the image data can be processed in real time on-orbit using artificial intelligence technology , automatically select the ground station and establish a connection to download the ground at the first time. Therefore, the difficulty of ground missions on the D star of “Tianzhi II” will be greatly reduced, and the timeliness of information will also be greatly improved.

According to reports, after the “Tianzhi-2” D star enters orbit, it will carry out a new generation of intelligent satellite architecture and space-based intelligent software stack verification tests in orbit for the first time to evaluate the in-orbit application efficiency of multi-party algorithms and models.
