Advanced Receiver Terminal for User Services
Background & Objectives
While the Galileo core system is developed in the frame of the ESA IOV phase, supported by the GSTB experimentation test beds, it is necessary to develop the necessary user application-driven user terminals in parallel, ensuring that commercial competitive receivers are available either as products or through applications and services as soon as the Galileo service is available.
The main goal of this project is to implement and test a fully-fledged Galileo/GPS professional type receiver (ARTUS). As Galileo itself, as well as any Galileo signal sources, are not readily available, the second major goal is to design and build a Constellation Signal Simulator (MERLIN). As Galileo introduces new signal structures and becomes a new, innovative technology system, a central focus of the project is to develop corresponding new technologies for the receiver as well as for the signal generator.
The work in this project has been broken down into four interconnected main activities: - Investigation of core technologies - Development of ARTUS receiver prototype - Development of verification signal generator - Validation of the ARTUS prototype (with full receiver chain in real environment with SIS transmission). For further information, please refer to the picture.
The ARTUS project is targeted towards the investigation of relevant core technologies for the professional receiver development. Based on Galileo receiver pre-developments, GPS RTK bread-boarding and on a complete Galileo professional prototype receiver (ARTUS), a receiver will be developed which supports all three Galileo frequencies including EGNOS. A Galileo/GPS signal generator (MERLIN) is being developed for signal validation which the consortium plans to commercialise as an independent product.
