Abstract

With the performance improvement of satellite payload, satellite payload data simulators with high-speed and large-capacity are eagerly demanded by ground automatic test system for the testing of satellite data transmission system. Based on the analysis of traditional simulators, a new design with FlexRIO is introduced in this paper. Based on the PXIe architecture, the simulator mainly consists of data source module and data loading module. In-chassis high-speed data storage board is used as the data source module, which achieves a storage capacity of 2.9TB and is easy to extend. The data loading module is composed of FlexRIO and its adapter, of which the single-channel serial transmission rate is up to 1.2Gbps with TLK2711A as the transmission interface chip. And six channels are supported to work at the same time. Test results show that with high reliability and strong versatility, the simulator has no bit-error in laboratory. Hence, the payload data simulator can be used for satellite test directly, and can provide reference for the design of other high-speed data loaders.

基于FlexRIO的高速卫星载荷数据模拟器设计

随着卫星载荷性能的不断提高，地面自动测试系统迫切需要高速、大容量的卫星载荷数据模拟器，用于卫星数据传输系统的测试。本文在分析传统仿真器的基础上，介绍了一种基于FlexRIO的新型仿真器设计。该模拟器基于PXIe体系结构，主要由数据源模块和数据加载模块组成。数据源模块采用机箱内高速数据存储板，存储容量达到2.9TB，易于扩展。数据加载模块由FlexRIO及其适配器组成，其中单通道串行传输速率高达1.2Gbps，传输接口芯片为TLK2711A。支持6个通道同时工作。实验结果表明，该仿真器可靠性高，通用性强，在实验室中无误码。因此，载荷数据模拟器可直接用于卫星试验，并可为其他高速数据加载器的设计提供参考。
