Abstract Astronomers adopt a single system of star positions and motions for reduction of other observations. Relative observations of faint minor planets may make a significant contribution to the evaluation of systematic errors in this Fundamental System, and provide means of deriving a position system in ecliptic coordinates. New techniques, such as observations with the Space Telescope, must be evaluated for possible incorporation into a revision of the Fundamental System. A historical summary of the application of minor planet observations to the formation of astronomical coordinate systems is given. Then a project to investigate the systematic accuracy of the Fundamental System is outlined. Of the four observation types considered, ‘crossing point’ observations provide a unique stabilizing influence on any coordinate system incorporating them. Finally, some sources of systematic error and some methods of their treatment are discussed.
