Description

亚米级高精度定位接收机
技术领域
本实用新型涉及一种可广泛应用于民用领域的高精度定位装置,特别是涉及一种定位误差可控制在亚米级的定位接收机。
背景技术
定位技术经历了从机械、光学、电子、光电一体化以及卫星定位的发展历程,现代定位技术如GPS卫星定位技术,特别是差分GPS定位技术RTK(RealTimeKinematic)由于其高精度定位能力的优点已被广泛应用于生产实践。
基于卫星定位技术的发展所研制的定位接收机具有全天候、多功能、作业效率高、没有误差积累、高度集成和自动化、操作简便、数据处理能力强、容易使用等多方面的优点。尽管目前的定位接收机具有强大的测量功能,但是,实际工作中仍然有一些不尽如人意的地方,如容易产生不期望的干扰误差,包括天线相位中心变化、多径误差、信号干扰和气象因素、轨道误差、电离层误差和对流层误差等。随着市场对于位置准确度的需求日益增加,迫切需要采取各种手段以减少定位接收机的误差,保证高精度测量效果。
实用新型内容
本实用新型着眼于现有技术中定位接收机的定位误差问题,利用有效的技术手段减少了器件之间的相互干扰,从而提高了定位接收机的可靠性,使其定位精度可控制在亚米级别,同时也降低了生产成本和人力成本,有效地提高了生产效率。
一种定位接收机,包括顶盖、天线板、屏蔽罩、数字板以及底座,顶盖与底座之间形成一壳体,天线板、屏蔽罩、数字板均位于壳体内部,其中,屏蔽罩位于天线板与数字板之间并具有与底座相配合的边缘部,使数字板密封于底座内部。
本实用新型可适用于GPS、GLONASS、Beidou等各种定位接收机模式,支持RTCM3.0标准,其定位精度可控制在0.1-0.5m,利用铝合金材质达到了高可靠性,IP67防护等级,可在水下一米深度工作30分钟。
附图说明
图1为本实用新型所涉及定位接收机的结构分解图
具体实施方式
参见图1,该定位接收机包括顶盖1、天线板2、屏蔽罩3、数字板4以及底座5,顶盖1与底座5之间形成一壳体,天线板2、屏蔽罩3、数字板4均位于壳体内部,数字板4通过螺柱固定于底座内部,屏蔽罩3上设有相应的可供螺柱穿过的通孔,屏蔽罩3与数字板4之间间隔一定距离,天线板2位于屏蔽罩3上方,通过螺柱6与屏蔽罩之间间隔一定距离。屏蔽罩3具有与底座相配合的边缘部,使数字板4密封于底座5内,从而避免数字板4对于天线板2的信号干扰,进而保证了天线板2的接收灵敏度。屏蔽罩3可采用铝合金等金属材质。经过实际测量,加设屏蔽罩3之后,该定位接收机可将信噪比提升10dB左右,继而将定位误差减小至亚米级。
