Building on the success of FP6 projects (in particular the GREAT project), the GRAMMAR project seeks to address the mass market receiver by extending the current state-of-the-art technologies for the mass market segment.
The GRAMMAR project specifically addressing the following gaps, which have been identified as obstacles for producing high-quality mass market receivers:
- No economic solutions for accurate dual-frequency RF and baseband hardware;
- No existing GPS/GALILEO receiver solutions;
- Poor robustness and location availability in indoor and urban environments.
The goals of GRAMMAR are:
- The development of a hardware prototype for a mass market receiver using a single chip dual frequency receiver and an FPGA based baseband allowing rapid prototyping of advanced algorithms and techniques.
- The identification, evaluation and simulation of enhanced algorithm concepts for next generation mass market receivers.
The project will develop functional prototypes of the receiver and its components, enabling practical testing and demonstration upon completion of the project.
The project generated European competence in GNSS receiver technology by initiating R&D activities leading to cooperation between industry, research organisations and universities.
The project is a follow-up of the GREAT project (FP6). GRAMMAR focussed on the development of:
- multiple-frequency single chip GNSS radio front ends, designed to address the future plurality of advanced mass-market applications;
- baseband prototyping, implementing advanced features not yet available in mass market receivers;
- prototyping advanced algorithms to determine their suitability for mass market receivers;
- simulations, addressing algorithms and techniques for future receivers. Examples are: complexity reduced multipath mitigation and also non-line-of-sight detection and mitigation;
- suitability of inexpensive sensors and/or assistance from existing wireless networks for improved indoor and urban position solution robustness and availability.
Pursuing the effort generated in FP6 (project GREAT) in preparing the Galileo market by introducing Galileo technologies at an early stage, especially in the mass market receiver area. Furthermore, ensure a competitive advantage for European players in the area of Galileo receiver and core technologies.
