Magnetic field vector is a function of the position where the satellite stays. Thus autonomousnavigation for small satellite can be achieved by measuring the magnetic field vector.
地磁场矢量是卫星所在位置的函数，通过对地磁场的测量，即可实现对近地小卫星的自主导航。

For enhancing the ability of survivability and auto-control, the requirement ofautonomousnavigation is brought forward to the formation flying spacecraft and satellite constellation.
为了提高自主生存与自主管理能力，对各类星座及编队飞行的航天器提出了自主导航与定位要求。

In this paper, making full use of the constraint of constellation structure, an autonomousnavigation method of constellation based on inter-satellite measurement was studied.
