| Abstract: | Introduction] Ultra-short baseline positioning is an important underwater acoustic positioning method, the paper mainly solves the disadvantages that remote positioning of ultra-short baseline positioning spread fast and is not high accurate. Method] The paper introduced the principle of ultra-short baseline positioning system, analyzed the various factors which cause ultra-short baseline positioning error, and aimed at these factors, proposed the corresponding processing strategy. Result] Combined with practical application of Hainan Island Power Grid Interconnection Project submarine cable testing, validated the effectiveness that processing strategy of ultra-short baseline positioning overcome the disadvantages remote positioning of ultra-short baseline positioning spread fast and is not high accurate. Conclusion] Hainan Island Power Grid Interconnection Project submarine cable testing in practical application proves that the processing strategy in high accurate positioning at the bottom of sea direct at the disadvantages remote positioning of ultra-short baseline positioning spread fast and have low accuracy is effective. |
