Precise Point Positioning (PPP) has been used in several applications and showed quite high accurate results. Normally, such applications are either in static mode or in a quite stable kinematic mode. In this presentation we will access the results of a PPP experiment accomplished during an aircraft flight, in which the velocity reached up to 700 km/h. The reference trajectory was determined using multi relative positioning, providing precision better than 20 cm. The PPP results from the two flights were compared with the reference trajectory. We will present details of the flights, determination of the reference trajectory and the in-house PPP software developed for such application together with the results. From the results obtained so far, we can conclude that, as expected, the quality deteriorates with the aircraft velocity and that most of time accuracy better than 80 cm was obtained for the height component.
