Captive Trajectory System (CTS) is an advanced test system for predicting the release trajectory of the external storages, which commonly uses the six-degree-of-freedom (6-DOF) series mechanism as the motion mechanism. As the large inertia force and the accumulated joint error, the positioning precision of the series mechanism is not enough. Compared with the series mechanism, the parallel mechanism has the advantages of small inertia force and non-accumulation of joint errors. In this paper, 6-PTRT parallel mechanism is employed as the 6-DOF motion mechanism for the CTS. The ground calibration method of the CTS parallel mechanism is studied in the space-constrained wind tunnel environment:the method of measuring and calculating the position and posture of the moving platform is presented, the calibration model which included the clamped angel repairman of the linear drive platform is established, the structural parameters are identified base on the method of nonlinear least squares. After identification, the position accuracy of the CTS parallel mechanism is better than 0.1 mm and the posture accuracy is better than 0.05°. Finally the CTS parallel mechanism and the regular attack angle mechanism are compared in the wind tunnel test. The wind tunnel test results show that the position and posture accuracy of the CTS mechanism under wind-load meets the requirements of the force wind tunnel test.
