| 摘要: |
| 研制了一种低功耗的定位信标，用于长期服役于水下的海洋仪器回收出水后的定位搜寻工作。信标基于GPS射频组件开发，与仪器固定在一起，待整体浮出水面后，会启动位置信号发送程序，通过电信网络，将该信标的实时位置发送至终端。经测试表明，信标性能可靠，可为海洋仪器的安全工作和顺利回收提供保障。 |

| Abstract: |
| An acoustic release is an oceanographic device for the deployment and subsequent recovery of instrumentation from the sea floor in which recovery is triggered remotely by an acoustic command signal. In this literature, a low-power locator beacon was proposed for searching, locating, and recovering long-range underwater marine instruments. Beacon signals help synchronize, coordinate, and manage electronic resources using miniscule bandwidth. The proposed beacon was designed and developed based on a GPS system and usually fixed with a marine instrument for offshore operation. When the instrument emerges from underwater to the surface, the program for sending the position signal gets activated through the telecommunication network, and the signal of real-time position of the beacon sent to terminals is synchronized with the receiver. The experiment results showed that the beacon had a reliable performance and can guarantee the safe operation and smooth recovery of marine instruments. |
