Systematic error and random error are main factors affecting the positioning of biorthogonal signal underwater positioning system. Based on the operation theory of USBL, this paper quantitatively analyzes a theoretical analysis and simulation calculations on influence of different error sources on the positioning accuracy and qualitatively analyzes the effectiveness of the towed linear array shape measurement method based on biorthogonal signal through practical experiments. By comparing the measurement effect after correction by using the measurement array with the measurement effect based on the linear array, the effectiveness of the method is verified.

“…Positioning System [1][2][3][4][5] . But the above three positioning systems are too complicated and cost is high.In order to solve the above problems, supported by the National 863 Program, Naval University of Engineering has proposed a new type of underwater navigation system called MOSUNS [6][7]. The MOSUNS are composed of a transmitter and a receiver, the transmitter consists of four transmitting array elements that simultaneously emit a set of mutually orthogonal signals and receive signals using a hydrophone as the receiver.…”

When the transmitter of Multi-Orthogonal Signal Underwater Navigation System(MOSUNS) is installed on a moving platform, the rotation of the platform leads to positioning error. In order to solve this problem, the motion error modeling is carried out in this paper, the relationship platform motion parameters (translation rate, rotation rate, etc.) and the linear velocity difference between each transmitter element and the phase error is deduced, and the relationship between the positioning error of the MOSUNS and the platform motion parameters is further deduced. Based on the motion error modeling of moving platform, a rotation compensation algorithm was proposed to compensate the phase error caused by platform rotation, and then the positioning error was compensated. The motion error modeling is quantified by computer simulation, and the validity of the phase compensation algorithm is verified by simulation.

For the problem of positioning error due to the rotation of the platform when the transmitter of the Multi-orthogonal Signals Underwater Navigation System (MOSUNS) is mounted on a moving platform, this paper performs a motion error modeling. The relationship between the platform motion parameters (translation rate and rotation rate, etc.) and the difference of linear velocity among each transmitting elements and the resulting phase error is derived, and the relationship between MOSUNS positioning error and platform motion parameters is further deduced. Based on the moving platform positioning error model, a motion compensation algorithm is proposed to compensate the phase error caused by the platform rotation, and then compensate the positioning error. The motion error is quantified and analyzed by computer simulation, and the validity of the motion compensation algorithm is verified by simulation.
