Abstract:
To solve the problem of low transmission success rate caused by the internal disturbance of 4G and WIFI signals to the downward transmission of Beidou, this paper designs a message transmission project for Automatic Weather Stations (AWSs) based on Beidou to reduce the code error rate by increasing the transmission frequency. It promotes and establishes for the first time the Beidou dualcommander user group for transmitting the messages of AWSs, designs a special encoding format for AWS messages based on the transmission ability of Beidou user machines, and utilizes redundant frequentness to resend the messages that can be repeatedly received for 4 times to guarantee a steady and high transmission success rate. Besides, the AWS messages can be used by forecasters in 1 minute, showing a breakthrough in terms of stability and timeliness.
