所述北斗应用软件模块与所述北斗协议栈软件模块之间，采用所述数据链应用软件模块与所述数据链通信管理模块之间的接口协议。可选的，所述数据链应用软件模块与所述数据链通信管理模块之间的接口协议包括Arinc619接口协议。
其中，北斗收发机主要由射频前端、A/D转换器、基带信号处理和导航解算部分组成。射频前端接收卫星的射频信号，经前置放大器发大后，将信号下变频为中频信号，A/D转换器采样中频信号，把模拟信号量化编码为数字信号。
基带数字信号处理部分主要功能为：卫星信号的二维捕获、载波相位和码相位的跟踪，并且测算出伪距，最后导航解算部分采用一定的算法消除模型误差，求解伪距方程，解析出卫星接收机天线的地理位置，从而实现卫星定位。
北斗导航系统是我国自己的导航定位技术，使用安全可靠。除了定位导航和授时外还具有通信功能，这是其它卫星定位系统所没有的。利用这种独特不仅能够进行自导航，而且还能把自己的信息通过短报文方式传输到异地指挥系统或友邻单元。
短报文功能在信息共享以及应付突发灾害方面对用户很有帮助。北斗导航系统工作于L/S波段，大气损耗和雨耗比较小、传输时延小、反映时间短，通信服务覆盖我国全境及周边地区，可做到全域、全时保障。
定位信息通过短报文传输，定位信息传输包含两层含义：一是对于构成了隶属关系的北斗指挥机和终端接收机，终端接收机的定位信息直接由地面定位中心在发送给终端的同时发送给其上级北斗指挥机。
二是利用北斗报文通信信道，通过自己定义的数据格式进行指挥机与用户终端之间、终端用户终端相互之间的定位信息传输。第一种情况的定位数据传输直接由卫星地面定位中心控制，无需用户干预。
短报文通信是北斗一号所独有的功能，可为用户终端与用户终端、用户终端与地面监控中心之间提供双向的报文通信。每个用户终端都有一个唯一的ID号，用以标识用户的合法身份，并采用1户1密的加密方式。
所有报文通信均需经过地面中心转发，其流程如下：短消息发送方将包含消息内容和接收方ID的通信申请信号加密后通过卫星转发到中心站。地面中心站接收到通信申请信号后，将信号解密然后再加密，接着将加密的信号加入出站广播电文中，经卫星广播给用户。接收方用户终端收到出站电文后，解调出出站信号，然后再解密出电文，便完成一次通信。
北斗短报文通信具有以下的特点：
保密性好：可进行信源加密。
覆盖范围大：5颗星工作，覆盖中国全境及周边。
设备要求低：平板天线，发射功率低、设备价格低。
同时兼容导航功能。
主要提供数据通信服务。
使用费用低。
组网方便：以指挥型用户机为核心。
本实施例方法所述的功能如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算设备可读取存储介质中。基于这样的理解，本发明实施例对现有技术做出贡献的部分或者该技术方案的部分可以以软件产品的形式体现出来，该软件产品存储在一个存储介质中，包括若干指令用以使得一台计算设备(可以是个人计算机，服务器，移动计算设备或者网络设备等)执行本发明各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
需要说明的是，上述实施例只是本发明所介绍的优选实施例，本领域技术人员在此基础上，完全可以设计出更多的实施例，因此不在此处赘述。
对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
