Galileo high precision service (HAS), which is available from 2023 year, provides submetric positioning accuracy worldwide, offering a reliable and accurate alternative to traditional GNSS differential corrections (DGNSS) without the need for additional ground infrastructure. Companies are already getting added value from this very specific Galileo service.
Petrobras, world leader in deepwater oil and gas exploration, uses advanced satellite navigation technology to improve the positioning and maintenance of its "floating mining vessels, storage and unloading (FPSO)». The company is modernizing its FPSO positioning systems by integrating Galileo HAS, a step, which significantly increases operational reliability in remote offshore environments.
Task: ensuring reliable positioning of the FPSO beyond the reach of the DGNSS
FPSOs are key assets in offshore energy production, which allows mining, remodel, store and unload hydrocarbons directly into the sea. These vessels are often at a distance of more than 100 km from the coast, beyond the effective range of traditional DGNSS correction services due to spatial decorrelation effects. To maintain accurate positioning and guarantee trouble-free operation, Petrobras plans to upgrade its standard GNSS system - Attitude and Heading Reference Systems (AHRS) receivers with Galileo HAS support.
Decision: implementation of the Galileo HAS service
To achieve this upgrade, Petrobras will cooperate with Mitang, a Brazilian service provider, which will provide to 40 GNSS-HAS receivers with marine antenna, capable of withstanding prolonged exposure to marine environments.
The decision to adopt Galileo HAS was made because of its ability to provide sub-metric accuracy without the need for additional ground infrastructure. Unlike extension services, which have long been available in the northern hemisphere, HAS is the first free and easily accessible high-precision satellite solution for the Southern Hemisphere.
The European Union Agency for Space Programs is responsible for the development and promotion of Galileo HAS (EUSPA). Providing reliable and accurate satellite navigation capabilities, EUSPA supports industries worldwide to achieve greater operational efficiency, safety and stability. The adoption of HAS by Petrobras highlights the global impact of EU space technology on the energy sector.
Strategic cooperation
Looking ahead with the planned deployment of Galileo HAS, Petrobras intends to improve the accuracy and stability of its FPSO positioning systems. This initiative not only strengthens Petrobras' operational capabilities, but also demonstrates the transformative potential of European space technologies in supporting global industries.
