Design of GNC Module Test System Based on POP Technology
Abstract：The highly reliable POP process GNC module innovatively adopts a frameless structure, takes three-dimensional interconnection as the level planning criterion, integrates information processing components and a variety of sensors, realizes three-dimensional interconnection through three-dimensional stacking, and forms a guidance and navigation communication module with an orthogonal three-dimensional structure and multiple external interfaces. Due to its high integration and miniaturization characteristics, it greatly increases the difficulty of testing. The master-slave collaborative system design method is adopted to construct a new test system for miniaturized aerospace electronic products. The hardware part of the test system adopts a generalized and standardized design to realize the test of the product under special environmental conditions; the software architecture adopts hierarchical Component-based design combines unit testing and special testing to implement independent testing of product functions and performance. The actual application meets the test requirements for GNC products. The test system has complete functions and simple operation, which is conducive to overall maintenance and system-level debugging, and is a huge improvement in the testability and calculability of GNC modules.
