摘要
全球导航卫星系统-声学(GNSS-A)组合水下定位技术广泛应用于海底位移监测和近海勘探。传统的 GNSS-A 定位策略是在 GNSS 定位确定等精度海面换能器位置的假设下进行的,这削弱了单个海底换能器站的定位精度。本文提出了海面换能器对海底转发器的测量和转发器对换能器的测距测量的扩展联合调整(JA)。首先,我们通过声学射线追踪策略完善了换能器到转发器的定时观测方程系统,以减少与声速相关的误差。其次,我们建立了海底大地测量网络(SGN)定位的站间测距扩展 JA 数学模型。最后,在模拟和实际测量数据集中证明了所提方法的有效性。实验结果表明,所提出的方法优于传统的定位方法,尤其是在水平分量方面。
Extended Joint Adjustment of the Transducer and Seafloor Transponder for GNSS-Acoustic Seafloor Geodetic Network Positioning With Interstation Ranging Information
Global navigation satellite system-acoustic (GNSS-A) combined underwater positioning technique is widely applied in seafloor displacement monitoring and offshore exploration. The conventional GNSS-A positioning strategy is under the assumption of equal-precision sea-surface transducer’s positions determined by GNSS positioning, which weakens the positioning accuracy of single seafloor transponder-equipped station. In this article, the extended joint adjustment (JA) of the measurements of the sea-surface transducers to seafloor transponders and ranging measurements of the transponder to transponder is proposed. First, we refine the transducer-to-transponder timing observation equation system by acoustic ray-tracing strategy to reduce the sound-speed-related errors. Second, we establish the mathematical model for extended JA with interstation ranging measurements for seafloor geodetic network (SGN) positioning. Finally, the efficacy of the proposed method is demonstrated both in simulations and in real measurement datasets. The experimental results show that the proposed method outperforms the traditional positioning methods, especially in the horizontal components.
