| Descripción: | Precise Point Positioning (PPP) online was carried out on a set of daily observation files belonging to 13 GNSS stations of continuous operation in Costa Rica, which were adapted to three-time intervals: 24 hours, 6 hours in the morning and 6 hours in the afternoon. The study was conducted between week 1934 and week 1986. The main objective was to determine the influence of the different time intervals on the PPP solutions obtained through the Canadian CSRS-PPP online service and their discrepancies with respect to the coordinates calculated weekly by the Sistema de Referencia Geodésico para las Américas (SIRGAS) and that are currently linked to the ITRF2014/IGb2014 solution. The results showed that the differences in the geocentric components, in addition to the time interval used in the processing, also depend on the geographical location, which represents an element to consider if users contemplate this online service as an option for computation of GNSS observations. |
