摘　　要：为了提高车载惯导试验系统的通用性和易扩展性,使该平台能够对不同型号的惯导系统进行测试,文章设计与研究了一套新型的惯导车载试验系统;文章简要介绍了该系统的构成和硬件结构,根据系统特点选择Windows+RTX作为软件开发平台,阐述了该平台实时性与广泛的用户软件支持兼顾的特点,并根据平台结构将软件设计分为3部分,详细说明了3部分的实现方法;最终通过实例表明,通过这种软件平台搭建的系统与其他平台下系统相比,具有实时性强、算法运行可靠、结构紧凑、用户操作简单的特点。In order to enhance the universal ability and expandability of inertial navigation testing system in vehicle, and inertial naviga tion of different kind could be tested in the same platform, a new inertial navigation testing system is researched and designed, firstly its component and hardware structure is introduced briefly. Then according to the character of this system, Windows＋RTX （Real Time Extension of Windows） is chosen as operating system. This paper described that the chosen operation system has the quality with both real time character and general software support. Software design is divided into 3 parts due to the operating system＇s feature. And each part＇s realization approach is interpreted in detail. Finally, in conjunction with an example, comparing with system under other operating system, it＇s more time critical, more stable when running algorithm, more compact and more user--oriented.
