我国正在加紧建设区域性GPS导航增强系统.利用 “北斗一号”的卫星导航增强系统是我国计划研制和建设的广域差分GPS系统.利用增强系统的地面设施,对卫星进行监测管理的目的,利用它的通信链路实现卫星和地面段的通信.
我国目前拥有若干个分布全国的GPS跟踪站和人卫激光观测站,经过适当的改造即可执行对我国新一代导航卫星的监测任务.利用人卫观测的高精度特点,完成对我国的导航卫星的高精度定轨,为进一步的导航定位服务创造条件.
由此可见,我国有大量的地面基础设施,经过适当的改造即可为我国的新一代导航定位系统提供地面控制中心站和卫星的监测跟踪站,导航信息的注入站等,为卫星导航系统的建设节省了大量的开支.改造工作要进行严密的统筹规划,必须要考虑到地理的分布和各种不同类型地面站的数量等因素,使其在新系统中承担不同的职责,达到对原有地面设施的最优利用和完成新系统的最优设计.
3．与国外系统兼容,增强我国系统的可靠性与抗干扰性
为了抓住卫星导航系统所拥有的巨大商机,夺回国内市场,进一步参与国际竞争与合作,我国第二代卫星导航系统应该与国际导航系统兼容.
要做到与国外系统的兼容性,主要通过对GPS/GLANASS/Galileo三个系统和我国的卫星导航定位系统的卫星坐标系统、卫星钟时间标准、接收机信号及导航电文格式的研究,制定组合后卫星导航系统的响应信号通讯标准和数据格式标准,达到与国际同步,多星座组合导航坐标框架及时间系统标准及格式.
国家安全、信息战争、航天安全、海洋安全、抗灾救灾、交通安全、紧急救援、突发事故处理、探险等等与国民经济和社会发展许多领域紧密关联的事务,对卫星定位系统的可靠性和抗干扰性要求最高,必需保证在任何时候不受国外敌对势力干扰,且导航系统在空间覆盖和时间连续性两方面都是无缝连接的.
为此,需要采取相应对策：①导航卫星地面跟踪站的跟踪方式采用两种或两种以上,如增加具有抗电子干扰功能的卫星激光测距跟踪方式；②建立能同时跟踪多种导航卫星系统的卫星地面跟踪站网络,并建立星基增强系统,实现信息服务自动化；③开发能接收和处理多种导航卫星信号的多星融合接收设备及硬软件系统,提高定位导航的可靠性.
三、对发展我国民用全球定位系统的建议
我国自主的卫星导航系统的发展,必须立足于我国的基本国情,目标是要建成一个具有世界先进水平的区域（或全球）卫星导航定位系统,以满足高技术条件下局部战争对导航定位的需要,逐步建成一个战术性能良好,运行稳定可靠,于未来军事斗争任务和武器装备发展相适应,完全自主的卫星导航定位系统.该系统应是一个全天候、连续、三维、被动式的高精度全球导航定位和定时系统,支持陆地,海洋和空中用户导航定位的需要,同时能做到与GPS/GLONASS/ GALILEO系统兼容.
1．完全自主,适合中国国情
导航卫星系统必须具有自主的控制能力,不能把未来高技术战争的保障手段掌握在别人手中.系统的建设和发展必须符合中国国情,即要与国防和国民经济建设的需要相适应,又要与技术,经济承受能力相适应.
