随着通信技术的迅速发展，为适应社会的需求，满足用户的需要，必须提高软件开发水平，近些年随着嵌入式操作系统的兴起，嵌入式终端与GPS的结合更加完善了GPS的可视性、功能性和操作性，使GPS的泛用性得到增强，用户的数量增多使功能需求越来越复杂，其中就有部分用户对时间精度要求较高，需要专门的语句格式来解析，这也是GPZDA得到应用并推广的原因之一。-With the rapid development of communications technology in order to meet the needs of the community to meet the needs of users, the need to improve the level of software development in recent years with the rise of embedded operating systems, embedded terminal and GPS combined with more sophisticated GPS can be visual, functional and operational, the pan with the GPS-enhanced increase in the number of users to make more and more complex functional requirements, there is some time accuracy are higher, you need a special statement format to resolve This is also GPZDA application and promotion of one of the reasons.
