The availability of additional data within
the composite systems can also be used
to support optional means to provide
additional security mitigation techniques in a
cost-effective manner. The threats are
analyzed at signal level, at message content
level (for ADS-B and for WAM content level)
and also at GPS signal level.
Performance based surveillance
This is applied to the provision of air traffic
services and determines the minimum
operational, safety and performance
requirements for a Generic Surveillance
System supporting ATC services. Surveillance
performance depends on the performance of
independent systems including aircraft subsystems
and ground sub-systems. The
definition of an end-to-end surveillance
performance standard is therefore necessary.
The design of surveillance systems that
account for ground and airborne sub-system
requirements is different from a performance
based navigation approach, which considers
airborne-based systems only. The Required
Surveillance Performance (RSP) specification
links ATC surveillance services, airspace
types and separation minima with the
respective ATC surveillance data provision
requirements as applicable to a range of
typical ATC sector types within the airspace.
It is essential that the surveillance data
output from new and emerging surveillance
techniques and technologies can be
seamlessly integrated into the ATM
infrastructure. This implies among other
things a trustworthy and accurate
performance monitoring.
In this context, INDRA developed in
SESAR2020, Surveillance Performance
Monitoring (SPM) tools to enable the
harmonised performance monitoring of
surveillance systems. SPM tools seek to
identify degradation trends early, by using
both off-line and in continuous quasi
real-time processes, demonstrating the
correct functioning of the ATM surveillance
function at the individual sensor level or at
ATC end-to-end level.
Integrated video surveillance
Video surveillance is an enabler for both air
and ground detection of targets. With the use
of UHD/4K cameras for ultra-low sensitivity
and colour night-vision, video augmentation
provides a flexible and redundant
architecture for surveillance. These kind of
sensors can be easily integrated with other
complete solutions such as ADS-B and
multilateration or can be used with partial
measurements of other sensors to enhance
system performances, opening the field to
new ATM applications. Examples of this are
remote towers for both single and multiremote
tower operation, contingency towers
and as a global ATM contingency strategy for
Route, Approach and tower systems.
In airport upgrades, they can complement
the existing tower without the need of
auxiliary towers. Temporary mobile towers,
the evolution of the conventional tower to the
digital tower, introducing new functions and
concepts such as intelligent binoculars,
augmented reality, track object detection”,
“head-up display of integrated ATM /
A-SMGCS data and intelligent gap-filling,
replacing current CCTV systems used in
complex airports are other application fields
for this technology.
INDRA’s spirit is based on innovation and
the company continuously works to
development new ideas and concepts for a
range of ATM solutions in which the
company is an industry leader. These ideas
are at the service of the customers and evolve
the ATM world. Customers and INDRA are
creating skies together. v
