Abstract—GNSS receiver is one of novel sensors applied to accurate management and control technology for the construction tower crane. Since the low-precision of m-level navigation application based on GNSS pseudo-range observations, it is insatiable to develop requirements of intelligent command for the construction tower crane. To improve the monitoring accuracy for construction tower crane based on GNSS method, a high-precision monitoring approach applied to fixed-point and lofting of hoisting operation by GNSS carrier phase observations is proposed. It is applied to the intelligent command of hoisting operation for the construction tower crane, and a set of GNSS-based fixed-point and lofting of hoisting operation system, named as GNSS_PLS, is designed and developed. The experimental results show that, for 6 minutes (360 epochs) of the monitor station installed on the top of the construction tower crane, the minimum error of North-RMS is 0.009m, the maximum error of North-RMS is 0.015m and the average error of North-RMS is 0.013m; the minimum error of East-RMS is 0.008m, the maximum error of East-RMS is 0.014m and the average value of East-RMS is 0.011m; the minimum error of Up-RMS is 0.021m, the maximum error of Up-RMS is 0.036m and the average value of Up-RMS is 0.030m. The monitoring accuracy of intelligent command of the GNSS_PLS system is obtained to cm-level and the effectiveness and feasibility of the proposed solutions are verified.
