增加兩枚傳感器可有效提升GPS汽車定位精度

發(fā)布日期:2022-05-11 點擊率:73

一個來自西班牙的研發(fā)團隊最近發(fā)現(xiàn)了一種大幅度提升車內(nèi)GPS導航精度的方式——只需一些額外的廉價傳感器。
  該團隊表示,通過在汽車導航系統(tǒng)中加入速度傳感器和陀螺儀傳感器,他們就能精確的將這輛汽車定位在2m的范圍內(nèi)。這要遠勝于目前被使用在汽車中的商業(yè)GPS系統(tǒng),其精度最高只能達到15m。
  而這項新技術的好處在于,可以被改裝進任何一輛汽車,成本也不是特別高。新加入的傳感器只會提供準確的速度和方向信息,這些再和GPS數(shù)據(jù)相結合,以形成更加精確的結果。另外,該團隊還計劃將來在智能手機中實驗這項技術。
