TL;DR: The micro-modem is a compact, low-power, underwater acoustic communications and navigation subsystem which has the capability to perform low-rate frequency-hopping frequency-shift keying, variable rate phase-coherent keying and two different types of long base line navigation, narrow-band and broadband.

TL;DR: The goal of this work is to enable the task of navigating multiple autonomous underwater vehicles (AUVs) over length scales of O(100 km), while maintaining error tolerances commensurate with conventional long-baseline transponder-based navigation systems (i.e., O(1 m), but without the requisite need for deploying, calibrating, and recovering seafloor anchored acoustic transponders.

TL;DR: A series of experiments that utilize autonomous surface craft, equiped with undersea acoustic modems, GPS, and 802.11b wireless Ethernet communications, to acquire data and develop software for cooperative localization of distributed vehicle networks are described.

TL;DR: The goal of this work is to enable the task of navigating multiple autonomous underwater vehicles over length scales of (D(100 km), while maintaining error tolerances commensurate with conventional long-baseline transponder-based navigation systems (O(1 m), but without the requisite need for deploying, calibrating, and recovering seafloor anchored acoustic transponders.

TL;DR: The Compact Control Language (CCL) was developed for use with the WHOI REMUS AUV and is a set of messages that includes commands for AUVs and data messages for typical sensors that allows vehicles developed at different research institutions or commercial companies to work together, thus promoting interoperability.
