摘要：

Using the high-accuracy OEM board, which contains of BDS B1/B2/B3 and GPS L1/L2 frequency, this paper realized the embedded algorithm of RTK of BDS, GPS and BDS + GPS. Both static and ground kinematic tests were carried out to evaluate the precision of the embedded algorithm of RTK from BeiDou, GPS and BDS + GPS. In static mode, the results demonstrated that the accuracy of static zero-baseline was sub-mm for the horizontal component and 1 mm for vertical component using BDS. The proportion of the fix results were higher than 98 %. The accuracy of GPS for 10 km static baseline, whose difference of horizontal component was smaller than 1 cm and the vertical component was smaller than 3 cm, was better than BDS, whose difference for three component was better than 4 cm. The statistics accuracy of GPS for 10 km baseline was better than 4 mm for horizontal component and better than 2 cm for vertical component, and the BDS was better than 1.5 cm for horizontal component and better than 3.5 cm for vertical component. The proportion of the fix results were higher than 95 %. For kinematic baseline, the result of integration positioning was accordant to the real topography, and the standard deviation of adjustment of every epoch was better than 6 mm.
