Update Reason: Tender issue
Currently carrier phase positioning techniques assume the utilization of a professional receiver, whose main advantages are the reduced multipath impact and the dual frequency tracking capability. Furthermore, professional receivers have limited capability to track non-line of sight satellites, especially in challenging environments (like urban ones).Most of the GNSS users are nowadays exploiting mass market receivers. Those receivers are characterized by single frequency use (but for the future it could be also dual frequency) a high robustness signal tracking, and low C/No acquisition and tracking thresholds. Those capabilities increase dramatically the satellites availability in challenging environments (e.g. urban environments and urban canyons). However, tracking noise is typically higher, mainly because they are more sensitive to multipath than the professional receivers. The main carrier-phase based techniques are Precision Point Positioning (PPP)and Real Time Kinetic (RTK/WRTK).PPP is in principle a worldwide service while RTK/WRTK is a local/wide area service. Those techniques are normally based in professional receivers. The task included in this activity are firstly to do an assessment of the current PPP and RTK/WRTK state of the art algorithms performance when using mass-market receivers in challenging environments (e.g. urban).Secondly to improve those algorithms. Then, to defined a proof of concept (PoC) with a commercial chipset to test the most important aspects of the improved PPP algorithms and characterize its performance (accuracy and convergence time) in selected and agreed representative scenarios. The conclusions of the PoC shall be used for iterating the algorithms in order to improve them further. Finally, a set of recommendations, algorithms and PoC results shall be provided. Procurement Policy: C(1) = Activity restricted to non-prime contractors (incl. SMEs).
