|Abstract:||Over the last years Precise Point Positioning (PPP) has been receiving more attention as it provides a cheaper and simpler way than the differential techniques like Real Time Kinematic (RTK) to achieve decimeter precision levels for mobile users and even centimeter precision for static users. Nowadays, PPP techniques are mainly based in professional receivers with dual-frequency capability and high accuracy orbit and clock products in open sky scenarios. The high accuracy orbit and clock products are calculated by using independent ground networks that are not part of the GNSS systems. Those products are disseminated via communications links (e.g. GEO satellite) and cannot be obtained from the GNSS navigation message. Currently, the different GNSS systems are improving their satellite navigation message ODTS (Orbit Determination and Time Synchronization) accuracy with the years. In this paper we see firstly how much the GNSS ranging accuracy (mainly driven by the ODTS error) shall be improved in the GNSS systems in order to take advantage of PPP techniques, and secondly we analyze the performances, main drivers and limitations for mass-market (single-frequency) and professional users (dual-frequency) in challenging scenarios (sub-urban and urban).|
