摘要
长基线水声定位系统中,由于海况影响使得水声定位浮标的姿态及水下单元的位置参数不确定,导致系统误差增加。根据能量守恒定律和几何变换关系,针对定位浮标姿态及水下单元的位置准确性提出了位置参数的修正方法,通过仿真对修正前后的定位精度进行对比,证明方法可行,海试证明可有效提高系统定位精准度。
In the long baseline acoustic positioning system,the system errors are increased besause of the sea conditions influnce lead to the uncertainty for position parameter of underwater unit and posture of the acoustic positioning buoy.According to the law of conservation of energy and the relationship of geometric transformation,a correction method of postiton accuracy for the uncertianty position of underwater unit and posture of positioning buoy is put forward.According to simulation compared the modified precision with the original,it is feasible.The sea test prove this method an improve effectively the system positioning accuracy effectively.
