Instantaneous real-time kinematic (RTK) techniques are one approach to achieving high-accuracy positioning. The object of this paper is show the advantage adding velocity information instantaneous RTK In paper, from Doppler frequency measurements used help resolve integer ambiguities in LAMBDA method. urban areas, pseudorange can suffer significant errors due strong multipath, despite use advanced multipath-mitigation techniques. However, do not deteriorate as much pseudoranges, because multipath error on only range several centimeters. Our proposed method has been tested by both static and moving users sub-urban environments. Single-epoch ambiguity fixing performance was improved compared conventional resolution without information.
