中文摘要:
      目前利用泛在无线信号进行定位时所需要的特定辅助信息的数据格式和传输方式还没有出台相关标准,这在某种程度上制约了导航定位产业的发展。针对这一问题,提出了通过对卫星导航定位领域广泛使用的RTCM SC-104和NMEA 0183这两种国际标准格式进行扩展,使其包含泛在无线信号定位相关的辅助信息,并将其通过NTRIP协议进行播发,从而实现辅助信息数据格式和传输方式的标准化。该研究有利于传统高精度GNSS定位和泛在无线信号定位的融合,并为实现泛在(无处不在)的室内外一体化定位提供技术支撑。
English Summary:
      As there is no relevant standards issued on the data format and transmission mode of the special auxiliary information required for wireless signals of opportunity based positioning, the development of navigation and positioning industry has been restricted to some extent. To solve this problem, the expansion of the two widely used international standards named RTCM SC-104 and NMEA 0183 in the field of satellite navigation and positioning is proposed. The expanded standards draft will contain the auxiliary information for ubiquitous wireless signal positioning and would be broadcast via the NTRIP protocol, so as to realize the standardization of auxiliary information data format and transmission mode. This research is conducive to the integration of traditional high-precision GNSS positioning and ubiquitous wireless location, and could also provide technical support for ubiquitous indoor and outdoor integrated positioning.
