Orbital Imaging Corporation, the Earth-imaging subsidiary of Orbital Sciences Corporation, today announced the inauguration of its SeaStar Fisheries Information Service, which offers daily Fish Finding Maps, derived from satellite images of the world's oceans, to high-seas fishing fleets and to other fishing organizations. ORBIMAGE is currently a trial demonstration of its unique service, with full commercial operations set to begin on January 15, 1998.

ORBIMAGE's SeaStar Fisheries Information Service is the first of its kind

in the world. It uses imagery gathered from ORBIMAGE's OrbView-2 satellite to

create Fish Finding Maps that display the ocean's changing surface color.

These subtle variations in ocean color, stretching for hundreds of miles,

indicate the boundary between phytoplankton-rich water and deep, clear-water

areas where surface dwelling fish such as tuna, mackerel, and swordfish

normally feed. Using the daily Fish Finding Map, a fishing vessel's search

time for productive fishing areas is minimized, thereby reducing fleet costs

and improving operating efficiency.

Currently, a fleet of 50 fishing vessels are receiving SeaStar Fish

Finding Maps. Each day, by 6:00 a.m. local time, the Fish Finding Maps are

transmitted directly to the fishing vessels' on-board personal computers via

the INMARSAT global satellite communications network. Using display software

provided by ORBIMAGE, the fishing vessel captain is provided with the most up-

to-date imagery of the Atlantic, Pacific or Indian Oceans. In addition,

ORBIMAGE's oceanographers provide recommendations for the most productive

fishing areas. The maps are also available via facsimile transmission or over the Internet at http://www.orbimage.com.

The OrbView-2 satellite was launched aboard Orbital's Pegasus(R) rocket on

August 1, 1997. Since it was placed into service in mid-August, the

spacecraft has performed a virtually flawless mission. It is providing never-

before-seen color images of the Earth's ocean and land surfaces using the on-

board Sea-viewing Wide Field-of-view Sensor. These images not only have

commercial applications, but are being used by scientific researchers around

the world to study global warming and the Earth's biosphere.

ORBIMAGE is leading Orbital's entry into the expanding market for

satellite-based Earth imaging services. ORBIMAGE will employ a uniquely

integrated global system of imaging satellites, ground stations and Internet-

based sales channels to collect, process and distribute its imagery products.

During the next several years, ORBIMAGE plans to operate a fleet of four

satellites. ORBIMAGE currently operates OrbView-1, a commercial atmospheric

monitoring satellite launched in 1995, and OrbView-2. Initial phases of

construction for OrbView-3A, the third in ORBIMAGE's satellite family, have

already begun, with an expected in-service date of approximately two years

from now. OrbView-3A is designed to provide high-quality one-meter resolution

and hyperspectral digital images of the Earth's land surfaces. OrbView-3B is

another planned high-resolution digital imaging satellite with an in-service

date yet to be determined.
