GMCA Project

The Galileo Monitoring for Critical Applications (GMCA) project extends the GPS monitoring system (GPMS) designed and developed by DWI International and Integricom with spoofing and interference sensors, as well as extending it to be able to monitor Galileo signals. The project was sponsored by the GSA under the Horizon 2020 programme. In addition to Integricom and DWI, the following partners were involved in the project:

  • Qascom S.r.l (Italy): developed a dedicated spoofing detector
  • Chronos Technology Ltd (UK): developed a dedicated interference detector
  • Spirent Communications Plc (UK): provided system validation services

GMCA OVERVIEW

The aviation community has some confidence now in GPS and EGNOS, backed up by many years of study, data-collection and hands-on experience with these systems. Such confidence in new technologies like Galileo and Galileo-based solutions like Advanced RAIM (ARAIM) has yet to be established. It can be noted that historically this community has been reluctant to accept new technologies and has been slow to adopt them.

To derive full benefits of Galileo for the aviation community as early as possible, it is crucial that the community gains better understanding of what Galileo has to offer while these solutions are being developed. This includes the operational community (Civil Aviation Authorities (CAAs), as well as Air Navigation Service Providers (ANSPs), regulators) which are targeted by our solution.

The GMCA project was an extension of the existing GPMS system. Within the project, Integricom upgraded its Computation Engine with the following capabilities:

  • System suitability for multi-constellation, multi-frequency use.
  • An interference and spoofing module. This module allows interfacing to dedicated interference and spoofing sensors to deliver low-level information on the presence of both interfering signals in the GNSS bands. Within the project, the dedicated interference and spoofing sensors were developed by the partners Qascom and Chronos.
  • Addition of new data formats for multi-constellation multi-frequency use (including a data format for the sensors that were integrated).

DWI has similarly updated the affected components of the system, and has included numerous new display options to present the additional data to the users.
