Digital Imagery Workstation Suite (DIWS)
An integral element in the mission planning of the Tomahawk cruise missile,
the Digital Imagery Workstation Suite (DIWS) is a state-of-the-art, stereoscopic,
high-performance imagery processing and exploitation system. Designed to
generate the Digital Scene Matching Area Correlation (DSMAC) reference scenes
used by Tomahawk to achieve it's precision accuracy, DIWS is currently operational
in an ashore configuration at both CMSALANT and CMSAPAC, and will be operational
in an afloat configuration on-board all carriers. It is also scheduled to
go aboard amphibious assault ships (LHAs and LHDs) and in five Rapid Deployment
Suites for contingency operations. Developed for PEO (CU) PMA-281, DIWS
accepts and stores, on-line, large volumes of image data from tactical and
national sources as well as commercial multispectral imaging sources. The
data is rectified "on the fly"and is provided simultaneously to
multiple workstations so that operators experience no data access delays.
DIWS photogrammetrically "ties" several images together to extract
data and information with a high degree of absolute and relative accuracy.
In the Navy's afloat architecture, DIWS functionality has been enhanced
to satisfy the Navy Joint Service Imagery Processing System (JSIPS-N) requirements.
As such, it will serve as the Navy's imagery engine afloat facilitating
a true sensor-to-shooter concept by providing imagery products in near real-time
to support all Navy strike mission planning and rehearsal requirements.
DIWS is currently in production at GDE Systems, Inc.
