GMV has been awarded a contract for the implementation of the Galileo High Accuracy data generator (HADG), which will be the facility in charge of generating the high-accuracy corrections data to enable the provision of the Galileo High Accuracy Service (HAS).

The contract was awarded by the European Union Agency for the Space Programme (EUSPA).

HADG will ensure the continuous provision of HAS data with a proper rate, accuracy, availability, continuity and latency. The data will encompass orbit and clock corrections, biases, quality indicators and service parameters.

The HADG contract addresses a key infrastructure development of the Galileo program. The Galileo HAS, together with the Open Service Authentication (OSNMA) and the Commercial Authentication Service (CAS), is one of Galileo’s stand-out services, setting it apart from GPS or GLONASS.

The HAS will be an open-access service based on the provision of high-accuracy corrections transmitted in the Galileo E6-B signal (E6, data component), at a rate of 448 bps per Galileo satellite connected to an uplink station. The data retrieved by the user from the different satellites offering the HAS will be reconstructed, allowing the user to achieve an improved positioning performance.

As the project’s leader, GMV will be responsible for core project activities such as the provision of the algorithms for the computation of the high-accuracy corrections, which rely on GMV’s MagicPPP software suite for precise point positioning. GMV is supported by SIDERTIA in the area of cybersecurity.

The specification , design  and development phases have already been completed, and the project is progressing toward qualification of the system that will enable the execution of the necessary validation activities prior to the HAS initial service declaration, which is expected in 2022.

GMV presented the first version of MagicGNSS in 2008.
