%X The aim of this paper is to analyze the accuracy of Precise Point Positioning (PPP) technique, of points, using short observation times, performing the comparison with post-processed points (from an adjusted basis).Therefore, the coordinates and the precision of the points were compared, and also were analyzed the precision of the vertices. The points analyzed were collected in the urban area of the municipality of Jaguari/RS. The methodological procedures of this paper are divided into three stages: collection of GNSS data, post-processing and analysis of data. The analysis of the processed data obtained average accuracies of 1 cm, 1 cm and 2 cm, respectively, for E, N and H coordinates. The average accuracies of PPP were 59 cm, 86 cm and 169 cm, respectively, for E, N and H coordinates. The discussions of this paper are of great importance because, consequently, the obtained results suggest that using the PPP technique to obtain point positions with short collection times is problematic, since a minimum observation time is needed to avoid compromising the final quality of results.
