Fixed ambiguity Precise Point Positioning (PPP) with FDE RAIM

Abstract

Precise Point Positioning (PPP) has been one of the major research interests in the Global Navigation Satellite System (GNSS) research field in recent years. PPP is a promising method because it can provide centimeter level positioning accuracy by using only one GNSS receiver, without using local reference networks. It is clear that this can provide cost savings compared to the traditional Real Time Kinematic (RTK) method, particularly if high accuracy positioning is required in remote areas.
