Abstract

In this study, a low-cost GPS receiver that combines single-frequency carrier phase was used with the virtual reference stations technique in testing the feasibility study on densified control survey possible. The results of zero baseline test shows that there are approximately 96% achievement less then 1 mm for the baseline length. It is similar to the obtained test results of general dual frequency GPS receiver. The result reveals the stable and reliable quality of observation achievement. During the 1 hour static baseline test, within 7 km range, 72% of baseline reached fixed solutions, which conform to general densified control point survey demand. When collocate with e-GPS system producing Virtual Reference Station (VRS) data under static baseline test, 75% baselines are able to calculate fixed solutions in 10 km range and the maximum error is less than 3 cm. The results of combining VRS improve the baseline distance benefit of about 30%. When integrate the Single Frequency GPS with VRS observation data in 15m dynamic calculation, the obtained result can reach 90% success rate, horizontal positioning standard error of around 1cm.
