Abstract：Virtual reference station technique is usually used to compute approximate corrections to the true errors of rover’s position through interpolated algorithms,thus it can achieve the positioning accuracy of centimeterlevel,but ambiguity errors between reference stations is amplified in creating corrections of baselines between reference stations. The influence of double difference errors on VRS observations is different for using different interpolation algorithms. Through the comparison between a linear plane and higher order surface represented by a quadratic function, the conclusion can be drawn that the linear plane interpolation algorithm is fit for creating VRS corrections. Because it can weaken the influence of errors between reference stations on VRS observations, and the impact of network configuration is on the small side.
