A nano satellite remote-measuring and remote-controlling method capable of switching communication path relates to a satellite remote-measuring and remote-controlling processing method. Without increasing the cost and the complexity of the satellite, the ground also can remotely measure and control the satellite when a malfunction occurs on an on-board computer. In this method, through detecting whether the updating frequency and the communication of remote-measuring data sent by the on-board computer of a satellite system is normal or not, a ground tracking telemetry control station judges whether a malfunction occurs on the on-board computer or not; when a malfunction occurs, the ground tracking telemetry control station directly communicates with a plurality of sub-systems of the satellite through a measuring and controlling sub-system. The method provided by this invention is applicable to the remote-measuring and remote-controlling data transmission of the nano satellite.
