星基增强系统（SBAS ）中生命安全服务不仅能提高定位精度，也能改善系统完好性，目前在民航系统中已经进行相关的应用研究。RTCA DO 229D文件中规定了SBAS接收机的性能标准，对于安全性要求较高的民航用户根据这个标准制定了相应接收机生产规范和指南。但对于安全性要求较低的用户接收机还没有形成相应的规范。除生命安全服务外，EGNOS自2009年起就提供了开放服务（OS ），接收机制造商也生产了相应的接收机产品，但存在接收机设计欠佳的缺点。主要研究基于开放服务的接收机设计的关键技术，为GNSS接收机制造商如何利用EGNOS广播信息来提高OS的定位精度制定一套明确的标准，同时，也为北斗星基增强系统接收机制造商提供了一定的借鉴意义。

SBAS systems for safety of life (SoL ) applications enhance the accuracy but above all improve the integrity . The related research has applied for the civil aviation at present .The RTCA DO 229D provides the performance stand‐ards of the SBAS receiver .Civil aviation requiring stringent safety formulates the corresponding guidelines of the receiver according to the standards ,but users for lower security requirements has not formed a corresponding receiver standards . Besides the SoL service ,the EGNOS open service (OS) has been available since 2009 .Since then most manufacturers have partially followed the standards for the design of their products ,but some implementations may not be optimal in some cases .According to the key technology analysis based on EGNOS open service receivers ,the objective of this paper is to produce set of clear guidelines for GNSS receiver manufacturers on how to properly make use of the EGNOS broad‐cast messages to improve their positioning accuracy measurements for open service .Meanwhile the receiver manufactur‐ers of BDSBAS have certain reference significance .
