processor and the Windows 3.11 operating system. All
components are packed in ruggedized cases.
The GFMPL software is loaded via CD-ROM.

GFMPL provides four basic functions:
environmental data assimilation, environmental data
analysis, sensor detection range and coverage
predictions, and data file maintenance. GFMPL will be
discussed in detail in chapter 2 of this module. Keep in
mind that when the classified version of GFMPL is
operating with any of the IMOSS computers, that
computer, as well as any other attached devices or
networks, must be classified at the appropriate level.
When using the IMOSS in a network, you must take
precaution to ensure that classified data is not
inadvertently transmitted or made available to
The purpose of the communications module
(COMM MOD) is to receive alphanumeric weather
data and facsimile broadcast data via the HF receiver or
satellite (fleet environmental broadcast data) using
shipboard communications facilities. The receiver of
the module has the capability to connect to the host
ships antenna system or be deployed independently
with its own antenna. Currently, the communications
sub-system consists of either an IBM 760EL (model
U6F) or an NEC VERSA 2430CD notebook computer.
The system also consists of a Kenwood R-5000 HF
radio receiver or a Drake R8A communications
It also includes a Dymek DA100D
Tuner/Power supply receiving antenna and/or a Dymek
DA 100E all-wave receiving antenna and various
