Single-frequency L5 PPP-RTK with GPS, IRNSS, QZSS and Galileo

Abstract

The concept of PPP-RTK is to achieve integer ambiguity resolution (IAR) at a single GNSS user by providing network-derived satellite phase biases (SPBs) in addition to the standard precise point positioning (PPP) corrections. These corrections enable recovering integerness of user ambiguities, thereby recovering the full capability of the precise carrier-phase observations. This contribution analyzes the capability of single-receiver positioning with IAR using new L5/E5a-frequency observations from GPS, the European Galileo, the Japanese quasi-zenith satellite system (QZSS) and the Indian regional navigation satellite system (IRNSS). In the absence of network products for new systems, especi..
