Resumen:
Abstract?In order to obtain the highest precision in the absolute position estimation of a GNSS receiver, the Precise Point Positioning (PPP) technique, making use of pseudorangesand carrier-phase measurements, is particularly appropriate. To achieve this, precise data of satellite orbits and clock biases are required. These are provided in several products, characterized by their precision, latency, availability and sampling rate. In this work, a comparison between the application of ultrarapid and real-time products to our own PPP algorithms based on an Extended Kalman Filter scheme is made. The influence of each product on the receiver position estimation is analyzed using GPS measurements of reference stations, comparing their performance for a real-time application.
