| Abstract: |
| According to the demand of high accuracy measurement in range measurement system,a scheme of multi-station time difference positioning on the sea-borne dynamic platform is proposed.Firstly,the principle of multi-station time difference positioning is introduced.Secondly,the measurement error factor and accuracy of each part in multi-station time difference positioning system on the sea are analyzed,and each concerned key technology is in-depth discussed.Finally,the technical specification level of multi-station time difference positioning on the sea-borne dynamic platform is proved through testing data analysis,and the result shows that the performance of multi-station time difference positioning on the sea-borne dynamic platform satisfies the accuracy requirement of range measurement system. |
| Key words: multi-station time difference positioning sea-borne dynamic platform inter-station time synchronizing telemetry signal measurement |
