Abstract: With the advance of space technology,network has become a trend for spacecraft. Spacecraft needs not only transfer data to the ground,but also share the information with each other.By building the LEO satellite network,it is easy for spacecraft to transfer and share data.However the network access method is one of challenges of the LEO satellite network.If different access methods are designed for different LEO systems,that will increase the complexity of access methods.A unified access method was proposed by using the area-routing method.It will not only simplify the access method of spacecraft,and the design of satellite network system.In addition,the access method will be independent from the satellite network design.The computer simulation result shows the feasibility of the access method.
