Method for processing positioning data of marine rescue position indicating terminal

The invention discloses a sea rescue position indicating terminal positioning data processing method, and belongs to the technical field of data processing, and the method comprises the steps: analyzing Beidou message data, and obtaining the current latitude and longitude positioning data, UTC time and an effective flag bit of a person falling into water; designing an effective positioning data identification algorithm, and judging whether the positioning data is effective positioning data; designing a key effective positioning data identification algorithm, and obtaining key effective positioning data; positioning data identification and storage in a single communication period are completed, a positioning data compression algorithm is designed, and current effective positioning data and key effective positioning data are fused and transmitted to a back-end server, so that a rescue team can more accurately predict the position of a person falling into water and carry out rescue.
