Software development for the determination of instantaneous height of transducer based on the blend of GPS height and heave

In order to improve the accuracy of underwater topographic measurement, the method for the precise determination of instantaneous height of transducer is studied. The software, which is used for implementing the blend of GPS height and heave so as to accurately present instantaneous height of transducer, is developed. The software structure design, key techniques and main function modules including quality control, time synchronization, attitude correction, as well as signal extraction and blend are depicted in detail. Moreover, the software is tested and applied in the actual experiments. The results show that the accuracy and performance of the software are high and can satisfy the actual application.
