Real- Time CommunicationsIridium Modem

An Iridium Short Burst Data Transceiver operates on the iridium network to provide two way communications with remote stations. Features:

•70% smaller then the Satlink2 Transmitter •70% lighter then the GOES transmitter•50% half the cost of a GOES transmitter•Simple RS-232 interface Data Loggers•Uniform global latency (less than 1 minute) •Coverage in areas not served by cellular•Ideal for Ground Water, 2-way, Flood Warning, Alert applications•Communications costs as less as $22.00 per month

How Sutron Iridium works for USGS?

• Can easily with easily Interface with existing loggers• Provides 2-way Communications capabilities• Higher throughput – allows transmission of camera

images• Low power and lower acquisition costs• Messages transmitted look exactly like GOES msgs to

accommodate existing USGS & USACE LRGS/DECODES ground stations

• Used as redundant/back-up comms for Critical Stations
