The invention discloses a lossless switching method for inter-satellite data of low-orbit satellites, which specifically comprises the following steps that: S1, a user terminal sends a measurement report to a network controller according to the generated measurement report, S2, the network controller executes switching judgment, if switching can be carried out, S3 is executed, and if switching cannot be carried out, S4 is executed, S3, it is judged whether the target satellite resources are allowed to be switched or not, if yes, S5 is executed, and if not, S4 is executed, S4, switching is notcarried out, S4', it is judged whether the user terminal of which the signal stays on the original satellite has a switching continuing demand or not, if so, S1 is executed, and if not, the switchingaction is stopped, S5, the target satellite allocates channel resources to the allowed user terminal, and sends a switching request instruction to the terminal through the service satellite, S6, the terminal receives the switching request and sends switching success information to the target satellite, S7, the network controller immediately releases the temporary storage data and S8, switching iscompleted. The device has the advantages of being simple in structure, smooth in network access and small in loss.
