The existence of secular trends between the dynamical system and the adopted system of the Fundamental Catalogue is studied by analyzing planetary observations of different types and by comparing them with a numerical theory constructed for the period 1769-1988. The theory parameters are fitted to ranging data for 1961-1988 for inner planets and to meridian observations of 18th-20th centuries for outer planets. A set of inner planet optical observations, which includes USNO meridian observations, transits through the solar disk, and occultations of fundamental stars are discussed. The time derivative of the gravitational constant G is estimated using radar data, and a new estimate of the relativistic effects in the motion of Mercury is obtained from the same data.
