NATO STANAG 7023 Document Information:
Title
Air Reconnaissance Primary Imagery Data Standard
North Atlantic Treaty Organization
Publication Date:
Sep 16, 2004
Scope:
NATO STANAG 7023 establishes a standard data format and a standard
transport architecture for the
transfer of reconnaissance imagery and associated auxiliary data
between reconnaissance Collection
Systems and Exploitation Systems. NATO STANAG 7023 is not a
communications protocol nor is it a
document that will solve implementation issues concerning
communications. The design of any system
for communications robustness must be made in consideration with
STANAGs 7024 and 7085.
Figure 1 illustrates where NATO STANAG 7023 fits into the overall
reconnaissance architecture.
NATO STANAG 7023 works in conjunction with other NATO STANAGs 7085,
7024, 4575, 4545, 4559 and 3377
to complete the interface between the Collection System and the
Exploitation System.
The flow of information begins in the Collection System. The
information is formed into the STANAG
7023 format and then it flows to lower levels of the interface where
it may be transmitted on a
transport medium or saved on a storage medium. When the information
arrives at the Exploitation
System the reverse process occurs.
The following list of top level design aims for NATO STANAG 7023
establish a basis for the design:
• promote interoperability
• handle primary imagery
• handle mission/intelligence data
• work in real time
• minimise platform processing
• assume exploitation of imagery has no prior knowledge of source
• image format does not handicap sensor performance
• digital and analogue versions
• layered/modular architecture
• end-to-end protocol
• self-describing sensor data format
• addressable data files
• multi-sensor/multispectral
• hardware independent
• expandable
NATO STANAG 7023 is a self-describing format. The auxiliary data
defines the format of the image
data. This enables NATO STANAG 7023 to handle any image from any type
of sensor. Figure 3
illustrates this concept.
The remainder of this document will focus on the following areas:
• Data Structure - section 2 describes the methodology with which
the data is formatted.
• Data Content - section 3 identifies and categorises the
reconnaissance data to be
transported from a Collection System to an Exploitation System. In
Annex A, reconnaissance data is
divided into two functional categories:
• sensor data - actual imagery collected from a sensor,
• auxiliary data - information required by an image analyst to
derive intelligence information
from the imagery and the information required by the Exploitation
System to process the raw imagery
data into a form which is useable by the imagery analyst.
• Logical Data Format Encoding - section 4 defines the general
encoding requirements for the
data fields within the header and data files.
• Transport Architecture - section 5 defines the data structures
required for the movement of
imagery and auxiliary data across the transport media. This section of
STANAG 7023 establishes a
standard data format encoding for the transfer of reconnaissance
imagery and associated auxiliary
data between Collection Systems and Exploitation Systems.
• Data Packets - section 6 defines the structure of the data
packet to be put on the transport
medium.
