The invention provides a real-time assessment method for test precision of a satellite navigation user device test system. The method includes that test control software is used to configure parameters required by test items, a data simulation module is used to generate a required simulated scene file in an off-line mode by a software mode, during testing, a radio-frequency signal simulation function module generates radio frequency simulation signals required by the testing according to the simulated scene file generated by the data simulation function module, a user testing device receives the radio-frequency signals and acquires test data of the required number of samples, and thereby the on-line real-time statistical assessment is achieved. Accordingly, goals of procedure controlling of the test system, closed-loop adaptive controlling according to the test items and real-time on-line assessment for test results are achieved, and application requirements of the user device for dip tests are met.
Description
technical field [0001] The invention relates to the field of satellite navigation user equipment test systems, mainly based on closed-loop self-adaptive control, and realizes a method for real-time online evaluation of test results. Background technique [0002] The main task of the user equipment test system is to meet the acceptance test of a large number of various types of user equipment. The task focuses on the qualification test for the relevant performance of the user equipment. User equipment test systems are currently not adequate. In response to this situation, it is necessary to upgrade the test process control and result evaluation function modules in the test software of the user equipment test system, so that the test system can realize the control process, perform closed-loop adaptive control according to the needs of test items, and test results online in real time The goal of the evaluation is to meet the application requirements of the user equipment for t...
