※ 引述《professorK (yo)》之銘言:
: 更準確的GPS(Pixel 5 & 4a 5G)
這個gps更新好像是比較有料的
https://9to5google.com/2020/12/07/pixel-5-gps-improved/
簡要講一下,就是過去GPS在高樓林立的大都會會有問題
因為常常斷斷續續才能連到某一個方向的衛星,或是訊號被建築物反射給影響
一般來說的解決方法是透過計算去算出建築物造成的效應
但是實際上會產生雞生蛋、蛋生雞的問題
也就是"既然gps定位不準確,那要怎樣知道'目前'要對哪些建築物來計算修正定位?"
這次google透過導入現有超過3850座主要城市的3d模型來提供定位修正補償
目前明確列出來有支援的地方大概是這些:
North America: All major cities in USA, Canada, Mexico.
Europe: All major cities. (100%, except Russia & Ukraine)
Asia: All major cities in Japan and Taiwan.
Rest of the world: All major cities in Brazil, Argentina, Australia, New
Zealand, and South Africa.
實際效果怎樣我就不清楚了,看有沒有人有具體的實感?
