全球定位系统芯片控制是否受到传感器辅助的影响?
原标题:Is GPS chip control affected by sensor aiding ?

我的结论是,通过两种参数来要求电离层(采矿、采矿)不会改变在我的电话上保持电池动力(Gingerbread),因为卫星icon在一切时间都停留,全球定位系统状态从来不延伸到一些人过去所报告的TEMPORARILY-UNAVAILABLE。

Therefore I farmed out the control of the GPS to a service which had a timing Runnable in order to control the GPS myself. The service is a simple state machine with three states, IDLE, SEEKING and FIXED_AND_SLEEPING. When the machine is SEEKING the GPS is enabled, when it gets a fix of sufficient accuracy, it calls removeUpdates, to turn the GPS off and starts a Runnable which times out after a period set by a parameter in the service Binder interface and switches updates back on again and moves to state SEEKING.

我认为,在控制全球定位系统已经停靠或中断方面,我很不错了,因为根据向机器和航标线传递的论点,icon已经过去和现在都显示出了国家的变化。

然而,我的电话有一个特点是:

Use sensor aiding: "Set to use sensors to enhance pedestrian positioning when the GPS signal is obstructed. There may be variations between the sensor estimates and your actual location"

如果我看上去,那么我就看着原木线激动过去说像有些东西。

[HYPOS] NOMOVE Time 234940, PowerMode 0, Sato WeakSignal 181,全球定位系统Fixtime 0, Car 1, DOE 3

and the GPS icon sometimes turns off when I hadn t told it to. Well of course it s not moving as the phone s on my desk with the USB cable plugged in for capturing the logcat.

www.un.org/Depts/DGACM/index_spanish.htm 我很想知道,这是否是为了要求了解情况?

It never could have determined whether the GPS stayed on or not by using the GPS alone, as the GPS needs to be on to know how far the phone has moved.

www.un.org/Depts/DGACM/index_spanish.htm 如果传感器辅助器的转用,那么气速计能够随着时间的推移进行整合,获得大致的距离观,决定电话的移动不会超过敏度,并且告诉全球定位系统芯片去掉吗?

我试图看到,这将再次回头,但是,一旦我不把“U”带走一条电话,“icon”立即再次敲响。

如果没有信使对此作出明确声明,将不胜感激地收到任何意见或经验。

Just to give a background. Android has many location providers such GPS, GNSS , Network location Provider and Wi-Fi based provider. Most of these are propriety feature of chipset vendors and have there own implementation depending on hardware capability.
Now there is another domain that is called AGPS(assisted-GPS. Since GPS is low power signal in the range of >-120 dbm, we need more computational resource to track the settelite and calculate and estimating the position. Hence you can say GPS to be power hungry. Various techniques are applied to reduce the need of computational resource by aiding GPS. Some of them are cell-ID position, SBAS , XTRA, Sensors, Radio-assisted etc.

我认为,当全球定位系统传感器被转用时,你们的电力消耗是固定的。

通过<代码>requestLocationUpdates (mintime, minDistance)的两种参数将只界定数据更新参数,这些参数将使用你的CPU(不会使用许多权力)。

So, you can t really control your power consumption when your GPS sensor is activated.
