Big data message transmission method based on Beidou satellite

Abstract

The invention relates to a big data message transmission method based on a Beidou satellite, and the method comprises the following steps: a transmitting end compresses a big data message to obtain a to-be-transmitted big data message; the transmitting end sub-packages the to-be-transmitted big data message according to the maximum data length supported by the Beidou satellite, and adds a packet header for each data packet to obtain to-be-transmitted packet data; the transmitting end and a receiving end uses a retransmission timeout mechanism to transmit all packet data to the receiving end; the receiving end comprises the following steps: the receiving end and the transmitting end use the retransmission timeout mechanism to receive the big data message of the transmitting end; and the receiving end performs interpolation processing on the received big data message to obtain a high-quality big data message. The method is reasonable in design, improves the reliability and quality of Beidou short message transmission, solves the problems that a Beidou satellite communication system is small in transmission data volume and unreliable in transmission, and can be widely applied to the field of maritime satellite communication.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, in particular to a big data message transmission method based on Beidou satellite. Background technique [0002] During sea voyages, seagoing ships usually use satellite communication for data transmission. With the gradual enlargement and control automation of marine ships, the communication between operators on board and land personnel is becoming more and more important. During Beidou satellite communication, short messages are usually used for transmission. In order to convey communication information more clearly and effectively, seagoing ships can use multimedia data transmission means such as voice message / fax message for data transmission. Since the voice / fax message data is generally large, but the short message transmission in Beidou satellite communication has problems such as small data volume and unreliable transmission, so how to send voice / fax information to the d...
