In addition to the legacy GPS and GLONASS, new emerging systems, e.g. European Galileo and Chinese BeiDou became operational for positioning, timing and navigation purposes. The International GNSS Service (IGS) has initiated the Multi-GNSS Experiment for adaptation of new emerging systems. An increasing number of satellites of GNSS and their constant modernization allow conducting precise point positioning (PPP) with four constellations, namely GPS, BeiDou, GLONASS and Galileo. In this paper, the performance of quad-constellation PPP over Turkey is investigated using different observation time (24-, 12-, 6-, 3-, and 1-h) and elevation cutoff angles (7°-15°-30°). Ten consecutive days in 2018 (DOY: 324-333) and six IGS-MGEX stations are chosen within and around Turkey to conduct quad-constellation PPP. The results indicate that quad-constellation PPP increases the horizontal and vertical accuracy compared to the GPS only PPP. As the elevation cutoff angle increases, the accuracy improvements are getting higher compared to the unconstrained environment. The improvements in the vertical component are much higher than the horizontal component for most of the stations. The results also reveal that the number of outliers is significantly low for multi-GNSS PPP compared to the GPS only PPP, especially for short observation time.
