当您打开GPS和GPS通知的一些应用程序时,GPS状态信息会显示"SAT" ,"SIG" 和"TTF" 信息(我知道的最后一个),但是含义是什么意思前两个和它们旁边显示的数字/符号(如无限)的含义是什么?
更新: Android GPS状态的示例:
SAT 0/2 | SIG 19/∞ | TTF 27s
最后一个意思是"它需要27秒(到目前为止)来获取GPS信号" 。我不知道前两个和所有这些数字。

When you turn on GPS and some app subscribes for GPS notifications, GPS status info shows up with "SAT", "SIG" and "TTF" info (the last one I know, Time To Fix) but what is the meaning of the first two and what is the meaning of the numbers/symbols (like infinity) shown up next to them?
Update: example of the Android GPS status:
SAT 0/2 | SIG 19/xe2x88x9e | TTF 27s
The last one means "it took 27s (so far) to acquire GPS signal". I don't know about the first two ones and all those numbers.
Android开发人员定义了标准参数 gps状态要被应用程序使用。
应用程序明显可以提供超过最小信息,如 GPS状态& Toolbox ,其帮助页 和Android文档放在一起帮助解密。
SAT 0/2
卫星数量:GPS在使用中[+ Glonass在使用中] /总可见。所以你的手机可以检测到2个卫星,但没有人被用来得到修复(室内或尚未获得修复?)。这可能对应于文档中的 getMaxSatellites
。
SIG 19/∞
平均信噪比(0-40db)。这对应于 getsnr
在文档中。第二个值是 d iluity o < /强> f p 再验值 。你肯定是在室内或修理刚刚开始,所以没有修复位置的错误是 ∞
。链接Wiki表示应该丢弃具有值&gt的读数。
TTF 27s
是 getTimeToFirstFix
,因为自GPS引擎最近的最新重启以来接收第一个修复所需的时间。
Android developers defines the standard parameters GPS Status to be used by apps.
Apps can obviously provide more than the minimum information, as in the case of GPS Status & Toolbox, whose help page and Android documentation put together help decipher.
SAT 0/2
Number of satellites: GPS in use [+ GLONASS in use] / Total visible. So your phone could detect 2 Satellites but none were used to get a fix (indoors or yet to acquire fix?). This likely corresponds to getMaxSatellites
in the documentation.
SIG 19/xe2x88x9e
Average signal to noise ratio (0-40dB). This corresponds to getsnr
in the documentation. The second value is the Dilution of Precision value . You were surely indoors or fix just started, so without fix the error of the position is xe2x88x9e
. Linked wiki says readings having value >20 should be discarded.
TTF 27s
is getTimeToFirstFix
meaning the time required to receive the first fix since the most recent restart of the GPS engine.
