About this launch
Yaogan 31-04 is a formation-flying triplet of Chinese military satellites in roughly 1,100 km orbits inclined at 63.4°, assessed as a naval electronic-intelligence system. Yaogan is the public designation China gives to its military reconnaissance satellites; official statements describe them only as remote-sensing spacecraft for land survey, crop estimation and disaster monitoring.
