- Abstract
It is mature to measure gravity by using cold atom on ground at present. However, due to the space environment is different from the ground environment, therefore the technology and design concept on the ground can not replicate to space application completely. This paper deduces the dynamic equation of cold atom during on-orbit phase, by combining the measurement principle. The deduced result demonstrates the cold atom can not be used to measure the gravity directly like on the ground. The measurement elements are mainly composed of non-gravitational accelerations、 vibration accelerations and attitude coupled accelerations.
