摘要
应用PXI总线、扩频通信、软件无线电等技术,设计并开发了一种小卫星扩频应答机模拟器,可作为真实应答机的替代产品参与卫星初样产品桌面联试、与地面站对接等试验;同时基于PXI总线的灵活架构以及模块化设计思路,可实现快速升级,为新算法提供通用验证平台;采用成熟的地面测试设备以及星上产品与该系统进行联试,验证了该应答机模拟器调制、解调等信号处理功能的正确性和有效性。
A small satellite spread transponder Simulator, which is capable to replace the true transponder to join the subsystem test or check the compatibility of ground station TT^C （Telemetry Tracking Command） SCOE （Specific Check Out Equipment）, has been devel- oped. Technologies such as PXI bus, spread communication, software radio have been applied in the development process. It will be fast to update this simulator or convenient to provide a common platform for the new algorithm based on flexible architecture of PXI and modular ization design. The modulation and demodulation function has been verified by communicating with the on--board equipment and ground test equipment.
