The invention aims at a problem that the communication rate of each channel of a multi-channel data recording system in the prior art cannot be dynamically configured during use and problems related to the time synchronization mechanism of each channel and a specific navigation and positioning sensor, and relates to a multi-rate multi-channel time synchronization high speed data recording system.The system comprises a data receiving module, a synchronous clock module, a data synchronization module, an electronic hard disk and a data playback module. The rate of each channel can be dynamicallyand independently configured, time synchronization of each channel is realized based on the data receiving module, the synchronous clock module, the data synchronization module and the data playbackmodule, and time synchronization of the data of each channel is realized through the initial global timestamp of each channel data flow without relying on a specific data protocol of the specific navigation and positioning sens
