设计和开发了一种用于21英寸水下机器人的声学通信系统，该系统具有在两个频带中以多种数据速率工作的能力。该系统是专门围绕直径21英寸的蓝鳍机器人AUV设计的，尽管它可以适应较小的车辆（12英寸）或类似的自由淹没车辆。该系统包括高频（25 kHz）和中频（3 kHz）调制解调器，支持80 bps至5000 bps以上的数据速率。这两种调制解调器都采用四通道阵列来提高可靠性。高频调制解调器还用于通过使用工作组中所有车辆上的同步时钟的单向行驶时间测量来支持多车辆导航
An acoustic communications system with the capability to operate at multiple data rates in two frequency bands has been designed and developed for use in 21-inch AUVs. The system is specifically designed around the 21-inch diameter Bluefin Robotics AUV, though it could be adapted to smaller vehicles (12-inch), or similar free-flooded vehicles. The system includes both high (25 kHz) and mid-frequency (3 kHz) modems and supports data rates from 80 bps to more than 5000 bps. Both of the modems utilize four-channel arrays to increase reliability. The high-frequency modem is also used to support multi-vehicle navigation via one-way travel time measurements using synchronized clocks on all of the vehicles in a work group
