Real-Time Tracking and Monitoring Also Reduces Fuel and
    Maintenance Costs for Large Sugar Cane and Grain Harvesting
                             Operators

MCLEAN, Va. and CURITIBA, Brazil, Sept. 22, 2010 (GLOBE NEWSWIRE) --
NRG Telecom and Iridium (Nasdaq:IRDM) announce that Enalta, a provider
of technology solutions focused on the agricultural sector, has
equipped asset tracking devices with the Iridium-based Quake Global
9612 modem. Multiple agricultural customers, including Abengoa
Bioenergia, Delarco Agricola and Cosan, are utilizing this solution in
their sugar cane and grain harvesting machines.

The integration of the Iridium-based technology enables real-time data
transmission that improves complete operational management and
productivity, as well as reduces fuel and maintenance costs for large
sugar cane and grain harvesters.

"The Iridium-based Quake Global 9612 modem provided to Enalta by NRG
Telecom, an Iridium value added reseller, offers customers a
low-latency data communications solution for tracking field activities
in areas where there is no other reliable communications coverage
available," said Bernardo Rosenmann, CEO, NRG Telecom. "Enalta
customers on average are improving efficiencies by approximately 10
percent and reducing fuel and maintenance costs by about five percent."

The automated Enalta solution equips the harvesting machines with
work-event detector sensors and on-board wireless GPS technology that
monitors their speed, engine temperature, oil pressure and battery
tension. More specific sensors monitor the heater, radiator and brakes.

The sensors rely on Iridium's satellite network to transmit short burst
data (SBD) messages from the harvesting machines to monitoring stations
at pre-configured intervals in real-time. As a result, the need for
maintenance is reduced and the number of hours these machines can be
available is increased an average of 10 percent. In addition, the
sensors can detect or anticipate an issue on a machine from the middle
of the field, resulting in solving potential problems before they
occur.

"With the Iridium-based tracking devices, we receive the machine data
in real time, allowing us the ability to collect, manage and analyze
complex information quickly and easily," said Renato Delarco, CEO of
Delarco Agricola, one of the sugar cane harvesting companies currently
using the Iridium-based equipment. "Being alerted immediately of any
irregularities in equipment assists in avoiding work stoppages and
allows preventive measures to be taken, ensuring production
efficiency."

"This service is ideally suited for equipment monitoring in the
agricultural sector," said Greg Ewert, executive vice president, global
distribution channels, Iridium. "Iridium's SBD service provides a
reliable, robust and cost-effective solution that enables these
companies to remain fully operational throughout their peak harvesting
seasons."
