摘要： Methods and systems for synchronizing clocks used in underwater devices is described. All clocks have some drift due to frequency accuracy and this disclosure provides a method for periodically synchronizing clocks to an accurate master clock to remove long term drift. A synchronization device can use an accurate clock and hardware to transmit both a sound wave and light pulse at the same point in time. Remote slave clocks can detect the light first, and later the sound, allowing them to calculate the distance the pulse had to travel. The clocks can then synchronize their time to the master clock canceling out any drift. The synchronization device can be packaged in a waterproof housing and can be moved around on a periodic basis between the clock on an underwater robot or any other means.

摘要翻译：描述了用于同步水下设备中使用的时钟的方法和系统。由于频率准确性，所有时钟都有一些漂移，并且本公开提供了一种周期性地将时钟同步到精确主时钟以消除长期漂移的方法。同步设备可以使用精确的时钟和硬件在相同的时间点传输声波和光脉冲。远程从属时钟可以先检测光线，然后再检测声音，从而可以计算出脉冲行进的距离。然后时钟可以将它们的时间与主时钟同步，从而消除任何漂移。同步装置可以封装在防水外壳中，并且可以在水下机器人上的时钟或任何其他装置之间周期性地移动。

摘要： Systems and methods are disclosed allowing for spatially separated nodes to transmit data to a single remote master receiver node in a synchronized way. Slave nodes can send acoustic data so that it travels through water and arrives at the master node exactly timed so that the data bit appears in a predetermined time slot. The next time slot could be a data bit coming from another remote or slave node in another direction and at a different distance. This can be repeated for many nodes and the incoming bits will be received in a time division multiplexed fashion at the receiver or master node. The senders address and bit meaning are implicit due to the time slot in which they arrive. The assumption is that all nodes have accurate synchronized time as well as the ability to accurately estimate sound travel time between itself and any master node.

摘要： A method for determining the position of an underwater device includes placement of a plurality of station keeping devices on or below the surface of the water in known positions. A device to locate is provided for placement below the surface of the water, and the device to locate and the station keeping devices are provided with a synchronized time base and a common acoustic pulse time schedule. Each station keeping device sends an acoustic pulse at a time according to the common acoustic pulse schedule. The device to locate receives pulses sent by the station keeping devices and calculates a distance between itself and each station keeping device based upon the time that the acoustic pulse is sent and the time that the pulse is received. The device to locate then calculates its position based upon the distances between the device to locate and the station keeping devices.
