The Application of Multi-source Data Verification and Validation Technology in TT&C System

Abstract

With the development of our country's aerospace industry, the unified TT&C system has been growing by focusing on the direction of automation and intensification, so as to meet the requirements of multi-targets and multi-models. As the recently adopted independent equipment surveillance collects limited information, it is hard to ensure that the status to be monitored in an all-round way and the malfunction to be analyzed at a fast speed. In this document, the whole system data collection function for the TT&C system has been fully utilized to conduct collection and analysis for a large number of real-time dynamic data with wide variety by combination of multi-source data integration theory, and has put the multi-source relationships into place and established the effective verification model, with the inspection of TT&C test, the comprehensive surveillance of the system working status and fast analysis and positioning of malfunction have been realized.
