Galileo In-Orbit Validation (IOV)

Galileo In-Orbit Validation (IOV) refers to the initial phase where the first Galileo satellites are tested and confirmed to work properly in space. This phase ensures that the satellites' navigation signals are accurate, reliable, and meet performance standards before full deployment. It involves verifying that all systems—like communication, control, and positioning—operate correctly in the space environment. Successful IOV tests are critical to guarantee that the entire Galileo satellite system can provide precise global positioning services for civilians, navigation, and various applications worldwide.
