"Iridium may typically be thought of as a satellite phone in the hands of a first responder," Ewert said. "Increasingly, government customers are seeking Iridium for tracking and redirecting of important assets in an emergency, including critical supplies, vehicles and even personnel. This is done through communications systems based on our data-only transceiver. Many first responders [during Hurricanes Katrina and Rita] were left vulnerable when it came to asset tracking. Supplies sat by the side of the road because communications were hampered with a lack of deployed mobile satellite services. They were unable to redirect supplies as needed. With our solution, they can stay in touch and stay in control."

Ted O'Brien, vice president of market development for the company, said Monday that the systems can be expanded as needed. Satellite telephone handsets are priced at about US$1,500 each, while a fixed base station that can be used in a rescue facility costs about $3,000, including an external antenna. The interoperability platform that allows satellite telephone users to communicate with VHF and UHF radio users -- as well as more than two dozen other systems -- costs about $10,000. Small mobile wireless modems that can be attached to vehicles and supply containers for wireless tracking cost about $500 each if tracking capabilities are to be deployed.

The equipment can be used with solar chargers so it can be recharged when power is out, or vehicle battery charger adapters can be used.

"First responders using Iridium tell us time and again that we're often the only line of communications they have, particularly during and right after a disaster strikes," Ewert said in a statement. "When communications infrastructure goes down, they need to get to the disaster scene and connect back to headquarters to coordinate their rescue and relief mission.... It usually takes several days for first responders to set up more permanent, fixed communications services in a disaster scene. They use Iridium to keep in touch and to coordinate their rescue mission as it unfolds."

Iridium Satellite provides global satellite voice and data communications, using 66 cross-linked satellites, according to the company.
