extended-HIgh performance MAss market GNSS receiver muLti stAndard readY for mArket (e-HIMALAYA)

The e-HIMALAYA project aims at prototyping innovative GNSS-based core technologies and concepts, with the objective to build key Galileo differentiators in a multi-GNSS hybridized receiver. Several markets are addressed with the main weight put on Mass-Market and transport, which represents the main Galileo receiver market.

The project will develop a list of key features to enable a higher penetration of Galileo compatible receivers on the market, and especially the ASIC developed under Himalaya project. First of all it will develop a high accuracy technology made available even in bad reception conditions, thanks to a robust aided PLL processing tuned for the Galileo pilot channels. It will also address a smart integrity function taking into account the local effects, through an ultra-tight coupling with inertial sensors approach. It also addresses improved performances thanks to an extensive improvement of telecommunication assistance dissemination. In particular, a robust anti spoofing function is also developed, prototyped and demonstrated.

The project will have several impacts:

• The first one is to build a ready to market localization solution based on an efficient use of Galileo.
• The second is to control key market levers technologies, and therefore propose a feedback both on standardization bodies, or future Galileo signal definition, and on the products roadmaps (GNSS ASIC).

Finally, the project will develop an indoor technology that is today seen as a very promising one, blending GNSS measurements and LTE ones.

DLR contributes in e-HIMALAYA to the development of:

• Develop and investigate high precision TDOA estimation algorithms for 3GPP-LTE.
• Reliable detection, estimation, tracking and mitigation of non-line-of-sight (NLOS) signal propagation biases in terrestrial mobile radio TDOA positioning.
• Provide its 3GPP-LTE (OFDM) positioning system for measurements, algorithm verification and prototype integration.
