Satellite orbit and clock products are the key elements for precise point positioning (PPP). Contrary to therelative technique, errors in satellite orbit and clock directly lump to the station coordinates for PPP technique. Currentlyfinal, rapid and ultra-rapid (observed-half and predicted-half) satellite products have been made freely available over theinternet mainly for Global Positioning Service (GPS) satellites. Final and rapid products are used for post-processingapplications. For real-time and near real-time applications, ultra-rapid products with predicted and observed parts can beused. There are several analysis centers that provide the satellite orbit and clock products. In this paper, accuracy andprecision of GPS rapid and ultra-rapid satellite orbit and clock products from two services, International Global NavigationSatellite Service (IGS) and Jet Propulsion Laboratory (JPL), were investigated in the position domain of PPP techniquewhile the final products of these services were taken as the true value. Ten IGS stations around the world were chosen forPPP processes. 24-12-8-4-2 hours of non-overlapping arc-lengths of GPS observations in 31 consecutive days (DOY 1-31of 2018) were processed for each station. The results confirm that the shorter the arc-lengths, the larger the relative errorof rapid and ultra-rapid products due to the similar Gaussian distribution pattern of the orbit errors with respect to the finalproducts. In terms of consistency between the products, Root-Mean-Square-Errors (RMSE) of final-rapid differences ofIGS and JPL are at the millimeter level. Millimeter level accuracy can be obtained using rapid and ultra-rapid products forJPL whereas only rapid products of IGS maintain millimeter accuracy with respect to the final products.
