Galileo satellites 27-28 were launched at the end of last year and underwent their in-orbit test review at the end of April, held between ESA, satellite manufacturer OHB and navigation payload maker Surrey Satellite Technology Ltd (SSTL). Their key findings included the fact that both satellites’ payloads are performing extremely well – among the best in the entire constellation – and that both satellites entering into service increase the position accuracy and robustness of the overall Galileo system.

A successful system/operations in-orbit test review followed, co-chaired by ESA and EUSPA, the EU Agency for the Space Programme, in overall charge of commissioning, which confirmed the satellites' health.

Now, following a successful test campaign this summer, these two new Galileo satellites have become the first to broadcast an improved navigation message, resulting in three key improvements for Galileo's public Open Service users.
