W1919EP 全球卫星导航系统(GNSS)基带验证程序库为 GPS 和北斗 2 卫星导航系统提供了端到端的系统建模和仿真,并为 Galileo 和 GLONASS 系统添加了额外的调制源。此程序库提供 GPS 和北斗 2 发射机和接收机的参考设计,以及包含对流层/电离层/多径效应的卫星信道模型,以便帮助用户仿真受到基带和射频减损影响的接收机性能。程序库还提供完整的多卫星场景文件,用于仿真系统在实际卫星环境(每个接收机的位置、日期、时间和持续时间均已给定)中的系统性能。
与主要用于在研发和制造阶段对成品元器件进行测试的测试与测量应用软件不同,W1919EP SystemVue GNSS 基带验证程序库更适用于早期的研发应用。SystemVue 程序库可帮助系统级架构师、基带算法设计人员和射频元器件设计人员在设计出硬件原型之前先进行早期的设计验证。SystemVue 支持脚本编程,并可链接到其他平台和测试设备,在整个产品生命周期内提供出色的灵活性和一致性。
图 1. W1919 GNSS 程序库针对 GPS 和北斗 2 提供了完整的系统级仿真参考,包括射频、基带算法和场景对位置不确定度的影响。
通过使用 SystemVue GNSS 程序库,用户能够仿真卫星导航系统在单卫星和多卫星信道场景中的性能(包括基带发射/接受算法和射频减损)。
**注:SystemVue 还可以通过定制与 Analytical Graphics, Inc(AGI)的 STK 10.0 惯性建模和地形建模软件集成。关于 SystemVue 和 STK 集成(取决于销售范围和出口限制)的更多信息,请与 Keysight EEsof EDA 咨询服务代表联系。
W1919EP SystemVue GNSS 基带验证程序库可作为选件添加到任何 SystemVue 环境或软件套件中。
