Abstract
Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is a Chinese mega-science project to build the largest and most sensitive single dish radio telescope in the world. To achieve precise positioning of FAST feed cabin, we need all-weather, large-span and high-precision real-time dynamic measurements. The coarse-adjusting measurement of the FAST feed support, uses RTK (Real Time Kinematic) with the fusion of BDS/GPS/GLONASS. This paper introduces the RTK measurement program of FAST feed support coarse-adjusting system. Combined with the measured data, it indicates the importance of BDS/GPS/GLONASS data fusion. We also use total station to evaluate the accuracy of RTK measurement. The results show that the accuracy of RTK with fusion of BDS/GPS/GLONASS meets the technical requirements, which can guarantee the normal observation and safe operation of FAST.
