This report provides estimates of the positional accuracy for celestial objects which have been obtained at the Experimental Test Site of the Ground-based Electro-optical Deep Space Surveillance GEODSS program. Optical observations made at the ETS have been compared with radar measurements performed by the Millstone Hill Radar. A brief description of the equipment and theoretical basis of the optical data reduction is included too. It appears that optical observations of artificial satellites, with real time reduction, are accurate to approximately 5. Author
