U-Space: A Comprehensive Overview of the Infrastructure

Table of Contents

The world of unmanned aircraft systems (UAS) has witnessed numerous breakthroughs in recent years, with the advent of the U-Space taking center stage in this transformation. U-Space is an all-encompassing term referring to a set of new services and protocols designed to support safe, efficient, and secure access to airspace for a large number of drones.

In this blog post, we are going to examine the U-Space infrastructure, the roles of the Common Information Service Provider (CISP), and the U-Space Service Provider (USSP), and an essential feature of the UAS ecosystem – the Network Remote Identification (NRI).

Network Remote Identification (NRI)

An essential component of the U-Space infrastructure is the Network Remote Identification (NRI), which provides critical data about the drone, including its identification, position, altitude, speed, and the position of the control station. The NRI is key to maintaining security, enhancing airspace awareness, and enabling effective traffic management.

The NRI is not merely a tool for authorities; it also provides benefits to the wider community. By making information about drones publicly available, it promotes transparency and public trust in drone operations.

Fundamentally, the NRI provides a mechanism for identifying drones in flight, hence playing a crucial role in deconflicting airspace, preventing unauthorized drone activities, and promoting overall aviation safety.

U-Space Infrastructure

The U-Space is an infrastructure that enables the integration of drones into the broader aviation ecosystem. Its range of services ensures drones can operate safely and effectively in all operating conditions, even in high-density areas.

The U-Space infrastructure comprises various systems and technologies that provide a comprehensive operational and regulatory framework. These include:

  • Surveillance systems: Real-time tracking of drones, other aircraft, and obstacles to maintain situational awareness and prevent collisions.

  • Communication systems: Real-time information exchange between drones, operators, air traffic control, and other relevant entities.

  • Geofencing systems: Enforcement of no-fly zones and other airspace restrictions.

  • Identity management systems: Unique identification and tracking of each drone, primarily facilitated by the NRI.

Common Information Service Provider (CISP)

The Common Information Service Provider (CISP) plays a crucial role in the U-Space structure. It acts as a data exchange platform where real-time and non-real-time aeronautical, airspace, and meteorological data can be shared among authorized stakeholders.

The CISP collects, processes, and disseminates data from multiple sources, such as air traffic control systems, drone operators, meteorological stations, and more. This information enables understanding the environment in which drones operate, contributing to the safety and efficiency of drone operations.

U-Space Service Provider (USSP)

The U-Space Service Provider (USSP) interfaces directly with drone operators and acts as the link between them, the regulatory authorities, and the CISP. Providing U-Space services to drone operators, including flight planning, flight approval, traffic information, and tracking services, the USSP ensures operators adhere to operational and safety requirements of the U-Space.

In essence, while the USSP facilitates drone operations in the U-Space, the CISP provides the necessary data needed for such operations. Together, they ensure a safe, secure, and efficient UAS ecosystem within the U-Space framework.


The U-Space framework, supported by CISP, USSP, and facilitated by NRI, marks a significant milestone in the integration of drones into the wider aviation ecosystem. This interconnected web of systems, services, and technologies is leading us towards an era of safe, secure, and efficient drone operations, ultimately shaping the future of aviation. The role of these components in enabling this shift cannot be overstated. They pave the way for innovative uses of UAS technology, creating opportunities for economic growth, and delivering benefits to society at large.
