摘要

软件无线电(SDR)技术应用于全球导航卫星信号(GNSS)的接收,可以实现具有高灵活性的定位设备。其优点是双重的:GNSS SDR接收机不仅可以在其使用寿命期间轻松更新,而且它还成为信号处理和信号质量监测创新算法原型设计的杰出工具。这些方面是由位于都灵的NavSAS团队开发的NGene全软件接收器实现的关键驱动因素。本文举例说明了SDR在GNSS接收机领域所带来的一些机遇。

Software Defined Radio technology for GNSS receivers
The Software Defined Radio (SDR) technology, applied to the reception of Global Navigation Satellite Signals (GNSS), allows the implementation of a positioning device with a high flexibility level. The advantage is twofold: not only the GNSS SDR receiver can be easily updated during its operational life, but it becomes an outstanding tool in prototyping innovative algorithms for signal processing and signal quality monitoring. These aspects have been the key-drivers to the implementation of the NGene fully software receiver, developed by the NavSAS group in Torino. This paper exemplifies some of the opportunities opened by SDR in the field of GNSS receivers.
