The European Union Agency for the Space Programme (EUSPA) has selected GMV to develop a new version of the High Accuracy Data Generator (HADG) as part of Phase 2 of the Galileo High Accuracy Service (HAS) development. 

This service offers free real-time precise positioning corrections to all Galileo system users. The first version of the HADG, also developed by GMV, is currently operational and provides users with the Initial Service (Phase 1) of the HAS. 

The new contract spans up to 45 months and has a budget of up to €12 million. It covers the design, development, deployment, and support to commissioning, along with optional maintenance of an enhanced version of the HADG. This updated version will integrate the functionalities necessary for providing the services outlined in Phase 2 (Full Service) of the HAS deployment. 

The new version of the HAS data generator seeks to improve the performance level of Service Level 1 (SL1) by deploying a new version of GMV’s magicPPP algorithms for precise corrections calculation and expanding the ground station network. This aims to provide global coverage and enhance the accuracy and availability of the SL1 service. Additionally, it will implement a new Service Level 2 (SL2), a regional service available only in Europe that will transmit atmospheric corrections to reduce the convergence time required to achieve maximum accuracy at the user level. 

Another key feature of the new HADG version is the implementation of a new functionality for the authentication of HAS corrections transmitted through the Galileo constellation, thereby increasing user security and confidence in the service. 

Since 2020, GMV has led the development of the Galileo HAS data generator following the award of the first contract with EUSPA. Since its operational launch in January 2023, the Galileo HAS service has provided accuracy for advanced applications in sectors such as navigation, agriculture, geodesy, and autonomous driving. In the new contract, GMV maintains its role as the main contractor and leader of an industrial consortium that includes atmospheric modelling experts from the Polytechnic University of Catalonia (UPC) and cybersecurity specialists from Sidertia.
