HTC 鑽石機裡面內建的GPS接收晶片是什麼的呢?
規格理都沒有寫說...

是SiRF STAR 3嗎?

正相關喔......
不管哪一套軟體,你看Sirf III在定點的航跡是在一區域裡分佈,而不是很穩定
(他特性就是會抓反射波,所以訊號才會強,定位速度快)
不管小弟用哪套軟體搭Sirf III >> 都會漂,就算軟體減少精度,也還是會漂
改用MTK晶片,訊號強,定位時間差不多快,任何軟體都不會漂
MSM7200搭星曆資料,就算訊號不強,定位時間同樣小於30秒,定點一樣不會亂漂

uncle_onion wrote:Yes. The testing supports your argument and give a counter example of what Suaaa claim qualcomm 不會亂漂.
that's what i said: qualcomm is faster than SirfIII
but SirfIII is more stable than qualcomm ( 比較不會飄)
