The Aldenhoven Testing Center is covered by six terrestrial transmitting antennas, so-called pseudolites, with a simulated signal from the Galileo system. This means that application systems can already be developed and tested.

Receiver data can be visualized online and recorded for offline analysis. Recorded receiver data can furthermore be played back.

[Schema: automotiveGATE]

Suitable Galileo receivers are required to use the system. GPS and EGNOS signals as well as the augmentation data of the local reference station can also be received and used. For the positioning modes, a distinction can be made between the base as standalone and the assisted mode using the correction data of the reference station. The latter has an accuracy of approx. 0.4 m.
