Ongoing Projects

GreeCom is the enabler of the Hellenic government satellite communications infrastructure that connects the country’s decision centres and authorities with voice and data services, with the goal of seamless and uninterrupted service even in times of crisis. In this context, there is a clear requirement for secure, resilient and reliable satellite communications.

The SMART project targets the design, development, integration and operational verification of a holistic user and resource communication service manager platform. The SMART solution is envisioned as a web application tool, which enhances GreeCom resilience, performance and security with the following functionalities:

  • Data network management and provisioning.

The system provides the basic set of services of an application-specific customer management platform. The specific module provides the service provisioning choices and packages, handles the demand requests, retains service profiles and health status, keeps the analytical history of the user, or administrator requests and responses, keeps service/user statistics and finally has the ability to generate relevant reports.

  • Bandwidth/Capacity resource planning and allocation.

The specific SMART module handles bandwidth requests, i.e., the user requests contiguous spectrum segments and provides information about the equipment and intended use. The SMART platform will have the exact view of the available and occupied resources. The overall managed bandwidth will be divided into two allocation pools: the fixed and the dynamic pool. The fixed pool includes long term leases – where the service provider has limited automated reconfiguration capabilities. On the other hand, the dynamic pool will be managed with real-time frequency planning and assignment, i.e., each request will be authenticated, examined and verified in respect to the available user equipment and based on usage history, and finally, a properly selected spectrum segment will be dynamically allocated to the user.

  • Spectrum and resource analysis using the Software Defined Radio (SDR) paradigm.

An SDR is a radio system that uses generic and simplified RF hardware, while the communication components that synthesize or analyse in the waveform are implemented exclusively on software – executed on embedded system and/or a conventional computer. In the SMART, SDR is used to implement a radio resource monitoring tool, in a time-frequency grid, that uses detection algorithms in order to: identify transmissions; classify them as licensed or unlicensed transmissions and estimate some signal features; and finally identify bandwidth segmentation, as well as monitor the resource utilization.

  • Optimized resource scheduling and allocation.

This component evolves the SMART platform from a management software to an automated and optimized resource allocation engine. In this context, the user requests dedicated throughput instead of specific spectrum segment. The system, in real-time will estimate the performance and select the optimal bandwidth allocation strategy that covers the user requirements and optimizes the overall system spectrum efficiency.

  • Automated ground segment control and monitoring

This element of SMART project will close the loop of automation and hereby create an agile and resilient system. The results of the optimized resource scheduling and allocation will be translated into a setting of the according ground station equipment. The equipment will be monitored and remotely controlled in order to adjust the device settings as it is required for a dynamic reallocation of resources.

  • A study on the definition of use cases addressed by a future Greecom network expansion and the technical requirements for the expansion will run in parallel to the SMART project objectives.

Following the increasing demand for satellite communication and earth observation capabilities the interest in Low Earth Orbit solutions has increased. Being able to utilize its own constellation of LEO satellites Greece can acquire a significant advantage, as it becomes independent of acquiring such data from third party providers, as well as enabling the ability of using a specialized payload, designed from the ground up to serve the type of observations needed in the needed satellite overpass frequency.

The SMART platform will provide proper interfaces towards users as well as third party applications – in order to provide extendable and scalable features.

The SMART platform is expected to have major impact into the GreeCom ecosystem since:

  • It develops new capabilities: With the use of efficient management, satellite resource allocation, monitoring and control of satellite communication capabilities, the achievement rate of the Governmental objectives will also increase. The efficient and reliable allocation of satellite resources at a national level is welcome by both military and civilian authorities – especially since it can effectively coordinate their co-existence. Furthermore, it will lead all the involved governmental stakeholders to consider new solutions to exploit the dynamically available satellite resources.
  • It eliminates distrust by governmental authorities. The reluctance of the different Governmental entities to cooperate in shared efforts/resources programs could be overcome through a centralized architecture which will implement joint plans for investment, exploitation and allocation of resources. In this way the fragmentation of efforts could be minimized and goals could be more efficiently be achieved.
  • It plays the role of the driver for future needs. The efficient monitoring of the allocated resources would be the driver of any future needs. The limitations that the current allocations impose to entities’ missions can help identify the requirements for furtherly expanding the current capabilities mitigating the current availability risks
  • It provides an accurate record guiding and harmonizing new investments in the domain. The system keeps accurate history and records of requests, allocations, system exploitation and resource utilization. These reports could guide the actions for any new expenditure for satellite related equipment, either on the ground or in orbit, aligning any capital expenditure with the current national strategy.
  • It creates new opportunities for beyond the national border’s cooperation. At an international level, a resilient, dynamic and, where possible, automated management framework allows two or more countries to use their allocation systems to jointly coordinate and share satellite resources, supporting each other in emergency (or not) situations. Joint resource management could be carried out with the exploitation of the SMART system that utilizes appropriate parameters and criteria based upon the situation in need.
  • It supports the satellite communications as field and solution. Based on the GreeCom experience, the use of satellite resources can be enhanced through efforts mutually conducted by the various Governmental entities. In order to achieve that level of cooperation, technical means are required which will efficiently manage and monitor the satellite resources among the various stakeholders.

The final objective of SMART is the definition of use cases addressed by a future GreeCom expansion and the definition of the related technical requirements. The use case definition will be performed through the determination of users and stakeholders’ needs.  The definition of scenarios of the high-level system architecture, the trade-off of satellite configuration, the spectrum requirements analysis within the limits imposed by the Radio Regulations and the identification of regulatory challenges are the main objectives to be reached towards the future GreeCom expansion design.

The project aims at the development of a new service, a cyber-physical platform that enhances the security over satellite public safety networks utilizing intelligent algorithms for anomaly detection, timely incident identification/notification, and efficient data routing. DEGREES will introduce new services to support crisis management through a communication framework with reinforced security and increased reliability.

The DEGREES platform consists of four main high-level components:

  1. The GreeCom Security Information and Event Management (SIEM)
  2. The GreeCom Cloud
  3. The GreeCom Network orchestrator
  4. Satellite Network

The value of DEGREES solution is highlighted by considering a use case, where a set of satellite-enabled services is offered, i.e.:

  1. Static or mobile (UAV-supported) data/streams from conventional cameras,
  2. Static or mobile (UAV-supported) data/streams from hyperspectral cameras,
  3. Static or mobile (UAV-supported) data/streams from thermal cameras,
  4. Data/measurements from crossing sensors and detectors.
  5. Voice-video communication with the backend.

The set of services is offered for provision of enhanced situational awareness at a challenging and/or remote environment, more specifically for border monitoring and control, management of refugee flows, and respective rescue operations.

The data are gathered from the sources through wired or wireless connections at multiple portable satellite terminals deployed in the region of interest (the area of the incident) and forwarded to the system backend.

However, the described setup exposes a large attack surface to potential malicious users with the objective to undermine its operation or intercept data and communication. It should also be noted that the platform may operate in a hostile environment with many possible enemy actors in its proximity. More specifically, the cyber-attacks may compromise:

  • Availability of the communication paths
  • Integrity of transmitted data
  • Integrity of processed data
  • Confidentiality of transmitted data
  • Assault system non-repudiation

DEGREES has the objective to introduce a service able to support the satellite platform in satisfying the aforementioned security requirements. The DEGREES platform treats three of the call objectives on the GreeCom Ground Segment, namely (and in priority order):

  • Cybersecurity
  • Data routing and communication interface
  • Public safety center for disaster management

Mild cognitive impairment (MCI) is a state of a cognitive performance below of what is expected for an age and an educational level, but above a pathological level. MCI is one of the early symptoms of Alzheimer’s disease characterized by significant memory impairment that does not, however, meet the criteria for dementia. MCI patients may forget important information previously recalled, such as meetings, conversations, or recent events but continue to exhibit normal functional activities. MCI is also linked to the impairment of other aspects of cognitive function, such as attention, language, visual or executive function, including the inability of a person to make the right decisions, judge the time or sequence of steps required to fully execute a complex task.

Long-term studies show that on a global scale 15-20% of people aged 65 and over may develop MCI. Besides ageing, a wide spectrum of diseases and clinical conditions are related to MCI. In the case of cardiovascular diseases (stroke, heart attack, etc.), in addition to motor deficiency, patients develop cognitive and affective disorders. The relation of MCI to Parkinson’s disease has been similarly examined. Aphasia, a non-amnestic single cognitive domain MCI, does not affect memory and patients still reason as normal but are unable to communicate their thoughts easily.

Given the increase of the proportion of older people in the world population as well as the sharp increase in the survival rate of patients with acute diseases which, however, affect their cognitive functions, the importance of developing MCI prevention and rehabilitation tools is obvious. In recent years the interest in cognitive rehabiliation has led to the discovery of pathogenetic mechanisms of cognitive impairment and the development of new approaches to the recovery of neurons of the brain.

To this end, neuropsychologists are now increasingly using information and communication technologies, including serious games. Digital applications can provide a great alternative with respect to traditional methods, as they allow the patient to practice cognitive functions with rich media, such as sounds and images. A rehabiliation tool capable of managing such types of training material can generate different and operative experiences supporting the recovery process of the patient, while also recommending novel exercises that are difficult to realize with hard copy approaches.

The COGNIPLAT platform is an innovative cognitive impairment rehabilitation tool that is developed for assisting elderly who have MCI but have not yet developed dementia. It is built based on a multi-disciplinary approach combining theories of neuropsychology, cognitive linguistics and speech therapy organized in five domains, one diagnostic and four training domains focused on enhancing cognitive functions through different game exercises. In addition, the platform is designed to automatically adjust the complexity and type of exercises by adapting the cognitive requirements of the games to the characteristics of each patient.

The Platform

The COGNIPLAT platform is an innovative cognitive impairment rehabilitation tool that is developed for assisting elderly who have MCI but have not yet developed dementia. It is built based on a multi-disciplinary approach combining theories of neuropsychology, cognitive linguistics and speech therapy organized in five domains, one diagnostic and four training domains focused on enhancing cognitive functions through different game exercises. In addition, the platform is designed to automatically adjust the complexity and type of exercises by adapting the cognitive requirements of the games to the characteristics of each patient.

The diagnostic domain aims to evaluate, through a specific set of exercises, the degree of impairment of the patient’s cognitive functions in order to determine the difficulty level of the exercises to start.

The remaining areas focus on the reinforcement of different cognitive functions through exercises.

The first cognitive domain is focusing on memory and includes exercises that focus on recalling the position of objects and patterns, a sequence of numbers, elements of associative knowledge etc.

The second cognitive domain focuses on attention with the use of exercises that request, for example, to replace words or phrases with images or image sequences and identifying objects displayed on the screen.

The third cognitive domain focuses on enhancing the perception ability with the use of exercises that require some kind of orientation or determining the location of an object with respect to another.

The fourth cognitive domain focuses on reasoning and problem solving with exercises such as solving arithmetic crosswords and selecting the right pattern to reasonably complete a given sequence.

In addition, the platform includes the implementation of game scenarios based on interactive 3D environments with activities from everyday

Virtualised service platforms and cloud computing hold great promise for delivery of large applications in e-Government. However, to date, the fundamental shared-resource nature of virtualisation technologies has raised legitimate security concerns for Government and other organisations with duties to protect confidential data. The PASSIVE project proposes an improved model of security for such virtualised systems which includes:

  • A policy-based Security architecture, to allow security provisions to be easily specified, and efficiently addressed.
  • Fully virtualised resource access, with fine-grained control over device access, running on an ultra-lightweight Virtual Machine Manager.
  • A lightweight, dynamic system for authentication of hosts and applications in a virtualised environment.

In so doing, PASSIVE will lower the barriers to adoption of virtualised hosting by government users, so that they may achieve the considerable gains in energy efficiency, reduced capital expenditure and flexibility offered by virtualisation.
