Summary:Receiver clock error is one of the key influencing factors to Global Positioning System (GPS) positioning accuracy. Generally, this error has higher impact on vertical positioning accuracy which is mainly associated to the stability of receiver clocks. In this paper, the vertical error in GPS positioning, which is driven by internal oscillators will be studied and compared to that driven by precise time reference (e.g., a Hydrogen maser). It is noted that vertical errors can be significantly reduced when the GPS receiver clock is steered by a stable time reference (Hydrogen maser). This paper highlights the potential and importance to improve the vertical accuracy by reducing the receiver clock errors.
