We introduce an application framework that enables easy implementation of applications that process GNSS Receiver External Interface Specification (GREIS)-formatted GNSS measurement data. The framework utilizes anti-aging techniques such as automatic code generation, documentation renewal, building, and component testing, which makes this framework effectively an always-up-to-date (“evergreen”) software. We also include an example case of the framework: a simple data inspection software for measurement data produced by Javad receivers, and compatible receivers, and data acquisition software with real-time telemetry. The framework is written in C++ and is available online.

GREIS格式的GNSS数据处理框架

我们介绍了一个应用程序框架，该框架可轻松实现处理GNSS接收器外部接口规范（GREIS）格式的GNSS测量数据的应用程序。该框架利用了抗老化技术，例如自动代码生成，文档更新，构建和组件测试，这使该框架有效地成为了始终最新（“常绿”）的软件。我们还包括该框架的一个示例：一个简单的数据检查软件，用于测量Javad接收器和兼容接收器产生的测量数据，以及带有实时遥测的数据采集软件。该框架是用C ++编写的，可在线获得。
