Towards precise mass-market positioning with Galileo

Future technologies like autonomous cars or augmented reality require low-cost solutions for precise (centimeter/decimeter) GNSS. This talk covers three research areas at ISTA related to achieve this goal. In low-cost applications, there is rarely the place to mount a geodetic antenna and more simpler solutions are sought. Smartphones are a good example. The impact of the antennas on the RTK positioning has been studied and first results are outlined. Galileo will provide on E6 within the next years a PPP-service called HAS (high accuracy service). In order that the correction data can be received interference issues with Amateur radio signals on the same band have to be resolved. Ambiguity resolution is essential to get a precise position. A signal candidate for an upcoming E1-D signal has been investigated. It is based on a multi-carrier signal and the success-rate to correctly resolve the ambiguities has been estimated. The talk ends with concluding remarks what milestones still need to be achieved for centimeter accurate smartphone GNSS and where we are in that process.
