Multi-GNSS Single Frequency Precise Point Positioning

Single Frequency-Precise Point Positioning (SF-PPP) processing strategy is a hot topic in GNSS context, owing to the advantages of a stand-alone, accurate and cost efficiency positioning. However, the existing SF-PPP methods can be hardly implemented for high-precision applications due to the large error sources that affect accuracy and converge time of PPP solution. For this aim, the paper proposes a SF-PPP approach based on the processing of code and carrier phase measurements from multi-GNSS constellation. The algorithm is tested using a static data collection carried out in an open-sky scenario. Results show a decimeter level accuracy on horizontal and vertical components of the position.
