INTEROPERABILITY
- Products
Capacities and Technology - Defense
The demand for NEC compatible systems comes from
the Defense and Security sectors, in operational scenarios such as
the following:
| 1. |
Crisis
situation management: |
| |
| a. |
Natural
disasters. |
| b. |
Fire extinction. |
| c. |
Terrorist attack. |
| d. |
Civil cooperation. |
| e. |
etc. |
|
| 2. |
2.
Military operations: |
| |
| f. |
In
peace-keeping. |
| g. |
Confrontation in
urban environments. |
| h. |
etc. |
|
This type of scenario calls for cooperation
between different forces and official bodies, both civil and military,
normally in an environment of coalition at international level. This
type of scenario calls for a change in the concept of instructions:
it requires leaving behind the concept of Task Managed Operations
(TMO in the NATO and EU terminology), and a change to Effect Based
Operations (EBO).
The EBO procedure concept has led to the development of the concept
of Network Based Operations (NBO).
An NBO scenario is underpinned by networks or information meshes,
which make interoperability possible between the systems and their
management. The objective is to manage to integrate the three main
elements defined in any operation in several interlinking networks:
| - |
Sensors. |
| - |
Monitoring and control
systems (information systems). |
| - |
Actuators (e.g., fire
extinction systems, sanitary transport means or weapons systems). |
The objective is for the information
to flow from the sensors to the actuators, with as little delay as
possible.
In this scenario, the information is not derived from one single point,
but rather from hundreds or thousands of independent information transmitters
and receivers: aerial photographs, site position data, vehicles or
encampments, situation forecasts, etc.. All this data is sent and
received in real time, and the applications can filter them depending
on the need for such information, in order to make coordinated actions.
Under EBO operations, since the end of the ‘90’s, development
has been underway in the engineering concept of NETWORKED SYSTEMS
(NEC, Network Enabled Capability, in Europe, or NCW, Network Centric
Warfare, in the U.S.A.), where the engineering is focused not on the
single, independent system but rather on the SYSTEM OF SYSTEMS, where
the engineering should be centered on solving the following challenges:
| - |
Share
the data and information between systems and physical heterogeneous
communications networks, with as little delay as possible
while optimizing the bandwidth available to the maximum. |
| - |
Availability of a real,
clear and concise image of the situation of the operations
environment (Situational Awareness Picture, SSA, or Common
Operating Picture, COP), with which the operation managers
can take decisions or execute appropriate actions, by optimizing
the use of the actuators to the maximum. |
| - |
Allow for collaborative
work among all the nodes in the system. |
| - |
Be able to synchronize
all actions in “quasi” real time. |
In short, the trend in the sectors
of Security and Defense is towards standardizing the NEC standard
systems, thus putting in place the NBO operation doctrine.
All this has entailed a notable investment effort for Nextel Engineering
in order to be able to adapt to this new reality. This investment
has been focused on two main aspects:
| 1. |
Training
at methodological level in order to be capable of managing
and developing the Systems of Systems (the NEC systems), not
individual systems. |
| 2. |
Training at technological
level in order to equip us with the required technologies
for integrating the NEC systems. In this new scenario, priority
must be given to excellence in the global system, as opposed
to that of independent systems. |
Middleware Technologies
Nextel Engineering has communications logic middleware,
based on the publication/subscription paradigm, compatible with the
most recent standards (SOA, DDS, HLA, etc.) optimized for use on “Network
Centric” systems.
In a NEC environment, the heterogeneity of the systems imposes encapsuling
information flows and the very transport and distribution of data
in a single component. This component is termed Middleware NEC or,
commercially, NCWare, which makes it possible to abstract communications
between the diverse systems, standardizing the interface and making
the applications in the physical communication architecture independent.
The main objective of this middleware is to allow for interoperability
between systems with heterogeneous interfaces (OMG DDS, OMG CORBA,
IEEE HLA, Web Services (SOAP) and SQL/ODBC/JDBC):
| 1. |
Integration
of the IEEE HLA standard. |
| 2. |
Integration of the OMG
DDS standard. |
| 3. |
Integration
of Relational Databases in the middleware, to enable access
to the middleware information using an SQL interface. In this
manner, it is possible to integrate control and monitoring
systems in the middleware based on relational data models
(e.g., MIP). |
| 4. |
Integration of the OMG
CORBA standard as a logical interface in the middleware for
implementing control and monitoring systems in this type of
distributed item. |
In short, the Middleware technology of Nextel Engineering
makes it possible to have a middleware with the capacity to integrate
practically any type of C3 or simulation system now existing, since
it offers the following types of logical interface for the applications
with which they are to be connected:
| - |
OMG
DDS interface (developed in previous projects). |
| - |
IEEE HLA interface (developed in previous objects). |
| - |
SQL/ODBC/JDBC interface. |
| - |
SOAP interface (developed in previous projects). |
| - |
CORBA interface. |
These interfaces are available in several deployment versions, each
being adapted for different types of HW configurations:
| - |
Hard-RT
version, prepared for operating in built-in systems, based
on deterministic real time operational systems and with operation
frequencies of > 100 Hz. |
| - |
RT version prepared for
operation at frequencies of < 50-60 Hz (valid for simulators,
built-in training, C4ISR, etc.) in PC type computers with
general purpose operational systems, Windows or Linux type
platforms. |
| - |
Mobility version. Prepared
for operation in mobile devices, with CPU restrictions, memory
and network connection with less bandwidth, HMI available,
etc. |
Development of Databases
in real time (in memory)
The use of database managers “in memory” makes it possible
to use relational databases in critical systems, with a performance
far superior to that of the databases in disk. The use of relational
databases in critical systems provides numerous advantages due to
the potential of the SQL interface for consultation and processing
of large volumes of data. These advantages are not always applied
to critical systems due to delays and low performance rates given
by given by traditional databases. Databases in memory make it possible
to improve the current situation.
Development of Technologies
Common Scenario Enabler
Techniques have been developed to make it possible to integrate all
the information from sensors and support systems into the decision
to make a Common Operational Scenario, in real time, able to provide
the same information to all the nodes connected to the middleware.
All the information is available for users on a common GIS system
that will allow for a common geo-referenced view of all the data and
elements of interest. Advanced personalization systems have been developed
on this common scenario, making it possible to define rules and filters
for each user so that each one is only presented with the relevant
information.
Capacities and Technology - Civil

The NEC concept is directly applicable to crisis situation management,
such as natural disasters, fire extinction, terrorist attack, civil
co-operation, etc. In this field, the resources involved will be civil
bodies and companies, but the needs and technology able to respond
to the same does not differ substantially from those applicable to
the field of defense. In fact, in certain types of crisis, the integration
of military resources may be vital, it becoming increasingly necessary
to use inter-operable technologies between the civil and military
fields (the UME is one such example).
Also, current training in crisis situation management is carried out
in exercises using real resources that are very complicated to organize,
with an associated high cost, with limited possibilities both in the
capacity to train and in the review and analysis of how it was carried
out.
The trend now, therefore, is to apply simulation
technologies to cover training needs. Training personnel would use
real control and monitoring tools, which would be fed by data from
a simulated scenario (effects of explosions, radioactive clouds, etc.),
whereas the orders transmitted by personnel would affect the simulation,
via mass behavior models, action models for response units (police,
fire service, medical services, etc.), communications networks, etc.
Along this line, it is essential to achieve the
necessary degree of interoperability between simulation models, between
C2 systems, and between the fields of control and monitoring and simulation.
The technology developed by Nextel Engineering is directly applicable
to Emergency monitoring and control systems since it is here where
NEC concepts are directly applicable:
| - |
It
is essential to cut down the time between detecting the focal
points of fire and their extinction. Here the direct flow
of information between the sensors and the means of extinction
becomes imperative. |
| - |
It is necessary to coordinate
numerous means of detecting, monitoring and controlling as
well as extinction. These means are highly heterogeneous and
may range from UAV’s or satellites as means of detection
to firemen contingents for extinguishing the same. The SINGLE
NETWORK concept of data, where heterogeneous systems inter-communicate
by means of middleware takes on prime importanc. |
| - |
Coordination between all
the resources involved in the operation calls for the availability
of a Common Scenario. The variability in this scenario over
time requires the capacity to be extremely swift in planning
extinction actions. |
| - |
The operation managers
require systems that help them in the decision-making process
and that reduce the overload of information. Help systems
are needed in the decision-making process able to provide
the manager with support in real time. |
| - |
Firefighting is notably
seasonal (in summer), and therefore, it is a fact that the
units are only operative for part of the year. Maintaining
all the resources involved in order and ensure a coordinated
operation requires ongoing training. This can be made more
realistic if it were possible to test out operations in simulated
environments, in a similar manner to how military operations
are simulated. |
