To increase future market opportunities and to differentiate from competitive products in traffic, transport and logistics, the following objectives are pursued:
The localisation precision is increased by combination of several GNSS systems (Galileo, GPS, possibly GLONASS as well) and by use of terrestrial and satellite-based augmentation services (e. g. SAPOS, EGNOS). For this purpose, a Galileo/ GNSS receiver is developed, which receives signals from several GNSS on various frequencies and calculates high precision positioning solutions by optimised sensor fusion algorithms.
The generated positioning signal contains validity information (integrity data). The receiver has to react adequately to an invalid signal. Central services can deliver the average reliability of the signalled position (e. g. from a comprehensive mobile radio network).
By interconnecting several sensors and by additional, externally retreaved information like map data, the availability of the positioning signal is improved even under shadowing effects.
To create a wide functionality with derivative marketing opportunities in traffic, transport and logistics, the four pictured core functions navigation, comunication, information and sensors result for the receiver as expanded Galileo receiver.
The Galileo Online receivers can connect to central services via suitable communication interfaces. From there, they can be monitored and controlled individually or in group. In order to be able to send data between receiver and central services, a suitable, bi-directional data protocol for mobile connections is developed within the project. Central services are basically designed and exemplarily implemented as modular components of background services, applications and customised solutions. The design focuses on the modularity and flexibility of the central services, further important aspects are data storage and data access, as well as the interaction with open and commercial services. The picture below shows a general system image of the mobile Galileo receivers, the communication network and the central services in a service centre.
The blue units represent a system, which demonstrates at the end of the project the exemplarily chosen railway application case. Possible objectives for a market launch, which are not part of this project proposal, are shown in green.
In the course of this proposal, an application szenario is exemplarily implemented to demonstrate the potential of the newly developed Galileo online receiver. The selected szenario is the one of automated shunting in a marshalling yard. At the entry of the marshalling yard, the wagons are equipped with receivers. This allows a high precision positioning of the individual wagons and its transfer to use it in the central services. There, an optimal shunting order is determined by a disposition application based on the positioning data and a predetermined train composition. Using this order, a suitable trajectory for the locomotive can be defined to assemble the freight train.
The application szenario is implemented first on a small scale. For this purpose, it is realised with test vehicles at automotiveGATE, which allows a hight grade of flexibility concerning the setup of different track systems. Afterwards, the algorithms are tested at railGATE in Wildenrath on a real track system. At the Havelländische Eisenbahn‘s marshalling yard Wustermark the positioning solution and the reception quality can be tested in a real marshalling yard under operating conditions.
To obtain project’s objectives, experts of localisation, communication and control are brought together. Each project partner is introduced on the corresponding sub-page.
