Abstract:

Deep space exploration relies on the high precision aerospace measurement means.However,the measurement system available in China can not meet the need of deep space exploration.The deep space exploration system in development is provided with VLBI,which has the unique ability of high precision angle measurement.Owing to the long distance between various stations,the VLBI system needs to send the acquired measurement data to related processing centers so as to obtain the measurement results.The data acquisition system,which is a key technology for VLBI measurement,needs to be further studied.

Key words: very long baseline interferometry;data acquisition system;data recording
