The International Association of Antarctica Tour Operators (IAATO) has approved a resolution requiring members’ passenger ships to be fitted with satellite tracking devices based on Iridium (Iridium Communications Inc.) (NASDAQ: IRDM). The devices will report ships’ positions at least once per hour when cruising in Antarctic waters. Global Marine Networks (GMN), an Iridium Value-Added Reseller, is supplying its XTracker™ satellite position reporting system for installation on the IAATO vessels. XTracker uses Iridium’s short-burst data (SBD) service to transmit position reports from the ships at sea to a shore-based server, which can be accessed through a secure Internet connection by ship operators, search-and-rescue authorities and other authorized users.
