Autonomous driving relies on extremely precise and reliable positioning – otherwise, it becomes dangerous
Complex traffic situations during merging and overtaking require the driver to pay extremely close attention, as carelessness during these maneuvers can quickly lead to accidents. Autonomous assistance systems can help to counteract this problem. The Precise and Robust Positioning for Automated Road Transports (PRoPART) project uses all the benefits of satellite signals as well as other navigation solutions, such as radar and cameras in the vehicle, to provide the vehicle with the highly accurate positioning in the decimeter range that it needs for these situations.
However, the satellite connection may be interrupted as the vehicle passes through tunnels or under bridges, and satellite signals can also be subject to interference or even spoofing. In these cases, the driver must take the wheel once again – before things become dangerous.
Our GOOSE GNSS receiver is able to bridge short signal interruptions so that the driver does not need to intervene even in situations such as these. GOOSE is already using the Open Service Navigation Message Authentication (OSNMA) service provided by the Galileo satellite navigation system, which is officially available from 2020 onward. This service transmits Galileo satellite signals with a form of encryption that makes it much more difficult to fake a position. With the help of GOOSE technology, we can therefore make complex traffic situations a manageable exercise for autonomous driving systems.
