Secondary Imagery Dissemination System (SIDS)

Primary Purpose To collect, transmit, receive, and exploit

current and achieved imagery products

electronically throughout the MAGTF using

available communications paths. Support

intelligence, weaponeering, and targeting for air

and ground forces. SIDS provides means to

transmit and receive exploited secondary imagery.

Sub-Functions The Man-pack Secondary Imagery Dissemination

System (Man-pack SIDS) consists of one (1)

base-station and three (3) Marine portable

outstations. The system is designed to collect,

process, manipulate and transmit digital imagery

derived from reconnaissance missions. The

outstation's primary components are a digital

camera with three lenses and a hand held

computer. In addition, there is one night vision

device per system, to be used with the camera in

low light situations. The outstation also comes

with cables that attach the camera to the hand

held computer, and the hand held computer to the

encryption device and radio. These cables are

required to transmit and receive the imagery

through the system. The base-station consist of a

lap top computer, removable PCMCIA hard drive

and a thermal printer. It also comes with the

cables required to connect with the encryption

device and radio.

Equipment Requirements SIDS consists of three separate but interoperable

systems: SIDS-E (External Connectivity), SIDS-I

(Internal Connectivity), and SIDS MANPACK. SIDS-E

will provide connectivity between the MAGTF

Command Element (CE) and external imagery

sources. This element will receive images from

external sources, annotate them as appropriate,

and input digitized images into the MAGTF's

internal dissemination system (SIDS-I) for

further use by MAGTF personnel. SIDS-I provides

the principal means by which the MAGTF commander

disseminates both time-sensitive, routine imagery

to subordinate commanders and their staffs. It

will allow G/S-2 personnel to receive, annotate,

store, print, and retransmit imagery to tactical

users. SIDS MANPACK provides small elements

performing intelligence collection missions with

the capability to transmit and receive imagery.

There are two versions of SIDS: Intelligence

Analysis System (IAS) and a man-pack variant.

IAS variant consists of the input/output

peripherals and software to process imagery from

various sources and disseminate imagery to MAGTF

elements or national assets. IAS hosts the

system and will interface with other C4I systems

through resident IAS communication links.

Man-pack SIDS variant is self-contained,

comprised of a base station and three out


Connectivity Requirements High-speed Ethernet connections, SIPRNET, JWICS,

single channel radio and STU-III.

Crypto Requirements Security required in conjunction with the transmission medium used and classification desired.

Normal Locations SIDS systems can be found at regimental/group

intelligence activities and above.

Information Managed SIDS facilitates digitized graphical information,

pictures and scanned/archived images.

Products Created Manipulated (black to white polarization,

zoom-in/zoom-out, rotation) and analyzed

secondary imagery and appended analyst comments.

Graphic reporting applications.

A change to the NITF standard is the JPEG2000

compression algorithm for use in downsizing an

image within the NITF file. JPEG2000 is wavelet

based and greatly enhances compression of images.

Lead Service/Contractor MARCORSYSCOM is the program manager. The Marine

Corps Tactical Systems Support Activity (MCTSSA)

is responsible for software management. Versions

of SIDS exist as all service components.

Current Fielding Status IAS suites reside at or above the regiment and

wing level. SIDS is post milestone III and has

been fielded to AAO units.

Known Problems Interoperability between various SIDS terminals

is problematic. SIDS is constrained to NITF 2.0

or compatible software, by bandwidth and data
