GRAMMAR (Galileo Ready Advanced Mass Market Receiver)

HWPrototype GRAMMAR prototype GNSS receiver

GRAMMAR coordinated by DLR represents a highly innovative approach to developing a prototype GNSS receiver, targeted at mass market applications, with the widest potential exploitation.

Goals

• The development of a hardware prototype for a mass market receiver using a single chip dual frequency receiver and an FPGA based baseband allowing for rapid prototyping of advanced algorithms and techniques.
• The identification, evaluation and simulation of enhanced algorithm concepts for next generation mass market receivers.

Key Issues

Significant effort has been devoted in FP6 to R&D for mass market receiver technologies. The GRAMMAR project will consider and analyze these FP6 achievements and expand and explore on new features for special mass market segments.

The activities will be based on the inputs from the prototyping results of the GREAT project (of which GRAMMAR is a direct continuation) and focus on the development of:

• Multiple-frequency low power single chip GNSS radio front end designed to address the challenge for a plurality of advanced mass-market applications. 
• A baseband prototype implementing advanced features not currently seen in mass market receivers. 
• Prototyping advanced algorithms in FPGA to determine their suitability for mass market receivers. 
• Simulations addressing algorithms and techniques for receivers beyond the current state-of-the-art such as complexity reduced multipath mitigation and non-line-of-sight detection and mitigation. 
• Studying the suitability of inexpensive sensors and/or assistance from existing wireless networks for improved indoor and urban position solution robustness and availability.

HWLTE GRAMMAR prototype LTE receiver

DLR contributes in GRAMMAR to the development of:

• Multipath mitigation algorithms for urban canyon environments.
• LTE-based localization algorithms taking into account non-line-of-sight (NLOS) scenarios.
• An FPGA-based prototype for hybrid LTE/GNSS localization.

Expected Benefits

• Generation of European competence in GNSS receiver technology by initiating R&D activities leading to cooperation between industry, research organisation and universities 
• Pursue the effort generated in FP6 in preparing the Galileo market by introducing at an early stage Galileo technologies, especially in the mass market receiver area 
• Ensure a competitive advantage for European players in the area of Galileo receiver and core technologies
