| Sumario: | Bernese GNSS Software (BSW) is a set of post-processing GNSS (Global Navigation Satellite System) packages providing high-performance processing, that provides estimates with high accuracy and flexibility in their applications. One of these features is the automation of scripts that perform Precise Point Positioning (PPP). The purpose of this paper is to analyze the potential of PPP in BSW. To achieve this goal, the coordinates of 90 stations from RBMC (Brazilian Network for Continuous Monitoring of GNSS Systems) were estimated in BSW and in the online IBGE-PPP service, in the current realization of the International GNSS Service, the IGS14, epoch of data. Then, they were compared with the reference coordinates of the stations (SIRGAS2000, epoch 2000.40), in three different ways: 1. Incompatible referential and epochs; 2. Referentials only compatibilization; and 3. Compatible referentials and epochs. The coordinate accuracy was reduced the process of compatibility of referentials. As expected, the predominant factor in the change in planimetric coordinates refers to their temporal evolution. In addition, the planimetric and altimetric accuracy presented descriptive statistics similar to the millimeter level, evidencing the potentiality of BSW in the PPP. |
