为什么TCXO晶振是导航与高精度定位的刚需器件
打开手机导航,车载定位,无人机飞行,户外测绘,物联网位置上报,我们早已习惯"精准定位,实时跟随"的使用体验.但绝大多数人并不知道:一套导航设备到底准不准,搜星快不快,轨迹飘不飘,断连多不多,核心并不只取决于定位芯片与天线性能,而是由一颗看似微小的时钟器件——TCXO温度补偿石英振荡器决定.在北斗,GPS,GLONASS等GNSS卫星定位系统中,TCXO是整机的频率基准与时间基准核心,被行业称为导航定位设备的"隐形精度标尺".普通有源晶振,无源晶振无法胜任定位场景的严苛要求,只有搭载高精度温补晶振,设备才能实现快速搜星,稳定跟踪,精准解算,长效定位.
