The payload will augment existing GNSS constellations with additional navigation signals from LEO, while relying on GNSS for orbit determination and time synchronization. FLORIAN KUNZI, BENJAMIN BRAUN, MARKUS MARKGRAF, OLIVER MONTENBRUCK, GERMAN AEROSPACE CENTER (DLR) / GERMAN SPACE OPERATIONS

Through a series of four vehicle experiments leveraging low-cost GNSS/IMU sensors, the findings from this research indicate that low-cost HAS PPP solutions can yield results comparable to those obtained using CNES ultra-rapid products at the 68th percentile of errors. DING YI AND SUNIL BIS

Europe’s first satellite-borne rubidium clocks have been in orbit for over a year. There is good news for the building of the Galileo system: the results obtained from GIOVE-A’s first year of operations show performance that is largely in line with the specifications.
