The invention relates to the field of communication technologies, in particularly to an RTCM message conversion method and an RTCM message conversion device. The RTCM message conversion method comprises the steps of: receiving RTCM messages sent by a reference station to form an RTCM message queue; forming a plurality of continuous bytes in the RTCM message queue into a buffering word; analyzing message information in the buffering word when the buffering word comprises a guide word; acquiring data in the RTCM messages according to the message information; and converting the data in the RTCM messages into target data and sending the target data to a base station. The RTCM message conversion method and the RTCM message conversion device can send all the RTCM messages in the reference station to the base station, thereby the base station can perform precise positioning or other application processing according to differential positioning data in the reference station and overcome the shortcomings of an existing RTCM2.3 protocol.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for converting RTCM text. Background technique [0002] In the system where ships and other means of transport communicate through maritime satellites, it is very necessary to locate ships and other means of transport. Services Version 2.3, RTCM2.3) or the VDM statement in the automatic identification system (Automatic Identification System, AIS) to transmit data, the base station realizes the positioning of the ship by obtaining part of the data in the reference station, but due to the existing agreement It is stipulated that the base station can only receive some sentences of the AIS protocol and RTCM2.3 protocol sent by the reference station, so it is difficult to perform accurate positioning based on the differential positioning data of the reference station. Contents of the invention [0003] In order to solve the incomplete compat...
