Resilience of Embedded Systems and Communications for Space and Aviation


Space networking

Space networks are currently being designed leveraging the mechanisms available for terrestrial networks. Many are suboptimal, given the challenges of the constellations and in some cases, these mechanisms need to be highly adapted or fully redesigned.

  • R&D of networking technologies in constrained environments
  • Requirements and design specification of intra- and inter-spacecraft communications and operations protocols
  • SW and support tools development for satellite network’s protocols and algorithms
  • Simulation, emulation and prototyping of space networks and assessment of their performance

Cybersecurity engineering for space

Security by design is to break at the same time of building so as to fix and reinforce the weak spots to not simply strengthen a space system, but to embed antifragility into it, in order to withstand a shock and to improve because of it.

  • Threat analysis and risk assessment (TARA) of complex space systems
  • Security requirements specification to fulfil programme cybersecurity objectives
  • Vulnerability analysis to find security weaknesses of space vehicle or ground systems
  • Penetration testing of specific components or entire small satellite vehicle systems

Secure systems design & implementation

The internet increasingly depends on space-enabled services and the operation of space assets increasingly relies on the internet. Traditional IT security expertise alone does not fulfil the needs of space systems and embedded security expertise is needed.

  • Secure boot and OTA updates for security throughout the entire lifetime of the system
  • Security measures for ground-space and space-space communication protocols
  • Fully customized and secure Linux distro for small satellites (e.g. for payload handling)
  • Hardening of real-time OS (e.g. RTEMS and FreeRTOS)

Cybersecurity engineering for aviation

The aviation industry is quickly moving towards digitalization and this rapid development with widespread connectivity capabilities opens the aviation industry to new challenges and vulnerabilities with unprecedented risks.

  • Threat and risk assessment (TARA) of aviation systems in compliance with EUROCAE ED-202 & RTCA DO-326 series standards
  • Aircraft and systems security risk assessments
  • Identification of security controls based on risk assessments' findings
  • Definition of methodologies, procedures, and processes to perform the cybersecurity-related activities

NETWORK as in a group of people sharing the same passion for technology and empowering each other to accomplish new, challenging and profitable endeavours that make a positive difference in society.

how we work

From listening to Sputnik’s tones to the precursor of GPS to accurately know your location with a smartphone nowadays, there was no single eureka moment. Instead, a series of findings from research, translated into the development of a platform to locate military assets on Earth, which evolved through the years. But when that platform was open and anybody could build upon it, the unpredictable power of open innovation became apparent. That is how we consider innovation happens. That is how we work. Chance favours the connected mind.

Open Science

We embrace the idea of open access for science as it positively impacts on how open innovation is produced by encouraging a more dynamic circulation of knowledge. As a science-based start-up we are keen on exploiting openly (not free!) accessible research results to support our customers and partners in creating innovative solutions to their needs.

Open Innovation

A well-functioning ecosystem allows co-creation and is an essential part of our process, in which stakeholders and partners collaborate with us to co-create innovative solutions. Confident in our skills, dedication and passion, we embrace coopetition, as well, as an opportunity to access markets where large firms dominate.

Open to the World

Our collaborators come from different regions of the world and cooperate internationally in research and innovation projects in the space industry with public and private organisations from the United States, the European Union, Brazil, Argentina, among others.

our services

We understand requirements and the business around them, and we provide clear, easily implementable recommendations on architecture, components, modules and interfaces for a system that fit the purpose in a cost-effective way.

By encompassing both tech guru skills and inspiring leadership, we provide instrumental support in the planning, scheduling and management of highly-technical projects in our fields of expertise.

Stemming from our product development experience and the engineering background, we support our customers on the journey from idea to production of space-related telecommunications or navigation product or services.

From concept to prototype to product, we support our customers in specific SW & FW development for communication or operation protocols, embedded security or signal processing for GNSS systems.

Emerging technologies alone cannot be relied upon to deliver a product or service. Our assessments facilitate responsible research and innovation, ensuring optimised design, implementation and use of technologies

We customise our services to support specific needs, such as surveying of state-of-the-art technologies, specifying applications or equipment and supporting on certifications and industry standards.

If security features are a design criterion, system errors and liability risks are reduced. We support our customers on the security-by-design process to make their embedded HW or SW products more resilient.

We provide security testing services for specific sub-systems of more complex systems under the premise that these tests should be performed at the lowest level possible, to verify the defence-in-depth strategy initially planned.
