Abstract: Context: Meridian transit circle observations of the planets and their satellites are regularly performed for ephemerides improvement. Some were performed at the Bordeaux observatory during the period 1997-2007. Aims: This paper presents these observations and analyses the data to determine the accuracy of the observations, their interest for dynamical purposes and compares them with the dynamical models of the observed objects. Methods: For the determination of the positions of the planets, the observations of their satellites have been used, providing pseudo observations of the planets. The method is tested. Results: The results show the interest of continuing this type of observation. Residuals show what ephemerides have to be improved using the present data.
