ESA expands Galileo satellite constellation to two new satellites

On Sunday, April 28, the Galileo navigation system expanded its constellation by deploying two additional satellites. With this recent expansion, the overall quantity of satellites will reach 30, while Galileo's capabilities will be enhanced in terms of reliability, durability, and accuracy.

Galileo, which has been operational since 2016, is widely acknowledged as the most precise global navigation system. It plays a crucial role in multiple industries, such as rail, maritime, agriculture, financial services, and rescue operations. This satellite navigation system is responsible for 10% of the European Union's annual Gross Domestic Product (GDP).

Under the EU's Galileo programme, the European Space Agency (ESA) and the European industry have successfully developed and tested a total of 38 Galileo satellites since its inception. The satellite constellation consists of four On-Orbit Verification Satellites and 26 Full Operational Capability Satellites, which were deployed in 12 launches.

Recent advancements involve the implementation of novel Public Regulated Service (PRS) signals, a cryptographically protected navigation service tailored explicitly for governmental purposes and delicate applications, augmenting Europe's self-reliance and adaptability in satellite navigation.

The remaining eight First Generation Galileo Satellites are scheduled for imminent launch, preparing for the deployment of the Second Generation fleet in 2026. The G2 fleet will incorporate advancements such as electric propulsion and enhanced navigation antennas, achieved through the collaborative efforts of ESA and European industry partners.
