An acoustic link (USBL) transmits basic telemetry and status information between the underwater robots and the surface ship. Due to the low bandwidth of the acoustic link, we are limited in terms of what data is transmitted while the robots are submerged. Once a robot has surfaced as part of its on-deck servicing, the onboard data is transferred off the robot and into the on-ship data center. Data is exchanged between the ship and the cloud-based servers via TCP/IP connection over satellite.
