Problems solved by technology

The existing positioning devices in these fields have the following multiple types: 1, the global satellite positioning system (GPS), but can only be used for object positioning on the water surface; Its fixed depth and fixed area; 3. The seabed-based system is fixed on the seabed and can only function in its fixed area; 4. The platform-based system can only function in the surrounding sea area when using an offshore platform
And because the sound, light, and electrical signals are greatly attenuated in water, the latter three devices are difficult to use in open seas, oceans, or deep seas.

Abstract

The present invention relates to a location coordinate system capable of retaining position stable marine work lifting-sinking compensation in underwater predefined depth and its location method. The system includes pressure sensor and transducer, controller, density change device, quickly in-position and reset device, power supply device and outer shell. The location coordinate system can utilize the control of density change device and quickly in-position and reset device to make it can autonomously drive and rise in the sea-water, and can dynamically be retained in predefined depth, location method is fast in response speed, short in transition time and quick and accurate in location.

Description

1. Technical field: [0001] The invention relates to a positioning coordinate system and a positioning method for marine operation heave compensation capable of maintaining a stable position at a predetermined underwater depth. An innovative technology belonging to underwater submersibles. 2. Background technology: [0002] In marine operations, the positioning coordinate system is often required as a measurement reference. For example, in the field of deep sea mining, the dynamic heave compensation of the mining system needs to obtain the heave motion signal of the mining ship, and the positioning coordinates are required as the measurement reference; in the field of marine environmental monitoring , in order to obtain strict and accurate underwater positioning data, the positioning coordinates are also required to provide a measurement reference. The existing positioning devices in these fields have the following multiple types: 1, the global satellite positioning system (...
