GMV supplies a Galileo second-generation RF constellation simulator

The European Space Agency has selected GMV to supply the radio-frequency constellation simulator (RFCS) for the Galileo second generation (G2G) program.

According to GMV, this is the multinational’s largest contract in Portugal.

From Portugal, GMV will lead a consortium to supply an RFCS covering both the first and second Galileo generations. The Galileo first generation (G1G), running since December 2016, consists of space infrastructure (26 satellites to date) and ground infrastructure.

Under the G2G RFCS contract, GMV teams in Portugal and Spain — partnering with Orolia and Tecobit — will develop an RFCS covering both Galileo generations as well as Galileo Open Service and Public Regulated Service (PRS). The RFCS will simulate the progressive deployment of the G2G with its new signals and will be key to supporting development of G2G infrastructure and testing of experimental user receivers.

The G2G aims to phase in new services, improve existing services, and boost system robustness. It also will enhance security while cutting operating and maintenance costs.

The RFCS will cover user characteristics such as dynamic behavior, signal impairments such as multipath and interference but also solution hybridization (for example, inertial sensors) and signal distortions. It will be designed to guarantee flexibility, configurability, modularity and scalability, as well as segregation of need-to-know information. For this purpose, the RFCS will be built with consumer-off-the-shelf products and follow a software-defined radio approach.

The project is closely linked with other PRS activities within GMV, identified as strategic for the maintenance of GMV’s European leadership position in the Galileo program.
