Abstract:

A remote communication system based on Beidou short message(Sms) is designed due to data transmission problems for some field spectral observation instrument working in remote areas. Through the cooperation of the circuit board, Beidou terminal and indoor data-center software, the system can implemented remote communication function. Supported by the system instrument can work without people, which avoids frequent access to the experimental field and remove manual measurement error. The data retransmission function designed in the system can solve the problem of Beidou packet loss. At present, the system has been applied to the automated-testsite-radiometer which had worked in Dunhuang Radiometric Calibration Field, and it showed that all performance meet the requirements. In addition, the system can also be useful for other equipments which need telecommunication.

Key words: Beidou short message, field spectral observation instrument, unattended work, Beidou packet loss
