摘　　要：Several autonomous navigation methods have been studied to reduce reliance on the ground stations.Geomagnetic navigation,gravity gradient navigation,and celestial navigation using optical sensors are typical autonomous navigation methods.Geomagnetic and gravity gradient navigation have low navigation accuracy(1301 m^([1])and 235 m^([2]),respectively)due to the poor accuracy of the geomagnetic and gravity gradient maps.Celestial navigation using refracted stars has the highest accuracy(146 m^([3])),but it is restricted by atmospheric density errors.
