GAWAIN work description:
- Definition of the user requirements
- Develop an End-to-End SW receiver simulator (Virtual Prototype), enabling maximum flexibility in algorithm design for different signal structures.
- Develop new Galileo receiver algorithms (acquisition & tracking), able to work with the new Galileo signal structure (and new GPS-IIF signal structure).
- Develop a baseband (I & Q signals) Galileo/GPS-IIF signal generator (adaptation from existing UMTS signal generator).
- Provide a real implementation of Galileo/GPS-IIF/UMTS signal algorithms on a real signal processing device (Baseband Prototype).
- Validate implemented algorithms using the I&Q baseband signal generator.
- Integrate signal processing device with a suited RHF-front end and antenna to a complete receiver device (Receiver Prototype).
- Add to baseband signal generator an existing RF-front end, generating real RF signals.
- Validate Receiver Prototype using the Galileo/GPS-IIF/UMTS RF-signal generator.
- Integrate receiver board into a complete housing (with power handling, I/F to application device).
- Test the Receiver Prototype in two completely different application test cases (real world application test), requiring also communication capability and using also standardized GIS interfaces (GML, …) for map display.
- The project will conclude with field tests and an evaluation phase (signal acquisition & tracking performance, signal robustness, interoperability, navigation performance, operational characteristics etc.), where also market prospects and the potential of GAWAIN is analyzed.
