Rugged DataBridge™ SDR
Case Study
Antarctic Geophysics Research
To study crustal rebound (a lifting of the earth's crust due to melting polar ice caps),
researchers at NASA's Jet Propulsion Laboratory (JPL) use high-precision GPS receivers to
accurately measure small changes in altitude at ground level both at the equator and at the poles.
The receivers provide about 60 MB of solid-state storage, but long-term (one-year) observations
often require 400 MB or more of storage.
The perfect solution.
To survive the harsh Antarctic environment, the researchers needed something better than a laptop or
desktop computer- a rugged, reliable recording device with low power consumption and wide operating
temperature range. DataBridge SDR™, a serial data recorder based on DataBridge technology, was
the perfect solution.
High capacity.
DataBridge SDR's equipped with 2.0 GB hard drives and flash disks ensure storage capacity for five years.
A high-speed SCSI port makes copying data from Antarctic observation stations quick and easy-crucial when
collecting data in the extremes of Antarctica.

A win-win partnership.
Acumen Instruments Corporation™ is working closely with a leading manufacturer of high-end GPS receivers to
bring the benefits of DataBridge technology to its customers. The manufacturer is including the DataBridge
OEM circuit board in its new receiver line, adding long-term recording capabilities and hassle-free network
connectivity for easy data retrieval.
