摘　　要：It is well-known that the integer ambiguities of network real time kinematics （RTK） in GPS can hardly be precisely resolved because of the small change of position dilution of precision （PDOP） within a few observation epochs. In response to this, an integer ambiguities resolution method aided by the high precision quantum ranging is proposed, in which the Householder transformation is employed to preserve the independence of different observations. Consequently, the reliability of the integer ambiguities＇ floating solution is improved mathematical analysis and simulation experiment are conducted to validate the effectiveness of the proposed method.It is well-known that the integer ambiguities of network real time kinematics （RTK） in GPS can hardly be precisely resolved because of the small change of position dilution of precision （PDOP） within a few observation epochs.
