Deep space detecting is the important subject for future space development. Teleoperation is the significant domain and indispensably essential technology of deep space detecting. The interactive mode of teleoperation is investigated, and the telecontrol and telemetry interactive process of typical deep space teleoperation closed-loop system is presented. Based on the direct control mode of teleoperation, the parameter of loop time delay is analyzed, and then the engineering calculation methods of loop time delay components are given. A modified way is proposed on dealing with the time of judging telemetry. The the-ory analysis indicates that the method can greatly improve continuous instruction efficiency,maximize sys-tem resource and decrease mission performance time.
