GPS软件接收机较之硬件实现的GPS接收机是一个巨大的进步，它充分发挥了软件的灵活性，不仅可以利用软件方法的优越性开发新的导航定位算法，还可以在不改动硬件的条件下进行传统算法的开发和验证，而且GPS软件接收机可以处理各种硬件收集的数据和各种频率的采样信号，便于接收机的升级。-GPS software receiver is the hardware implementation of GPS receiver is a huge progress. It makes full use of the flexibility of the software, not only can use the superiority of the method of software development new navigation and positioning algorithm, can also under the condition without changing the hardware of traditional algorithm development and validation, and GPS software receiver can deal with various hardware to collect the data and frequency of sampling signal and receiver for upgrading.
