EPO Tools Free

This tool is for Mediatek SoC based devices that use EPO files for AGPS functionality.

Currently support for MT6589/MT6592 is tested but it should work for any other Mediatek devices which use EPO files.

What makes this app different? Currently this is the only application that will automatically download the EPO files for you on a schedule in the background.

Use this application at your own risk! I recommend making full backups before using.

This application enables you to automatically download the EPO files on a daily, weekly or monthly basis if you would like to do so without any interaction required.

It has a One-Click feature(OK it's 2 clicks :D ) that enables you to quickly get some of the optimal settings for your device in your region.

A backup of your original gps.conf and build.prop files are made with automatic restore.

Requires:

*Mediatek device using EPO files

*Minimum Android version Ice Cream Sandwich

*Root access (Ideally with SuperSU, may work with others)

*Internet access

What are EPO files?

AGPS enabled GPS module can start-up faster, perform faster TTFF (time to first fix), and obtain faster positioning information under weak signal environments.

On average, using AGPS cuts the GPS module "cold-start" time by half, and "warm-start" down to one second.

When GPS receiver is powered on for the first time, almanac and ephemeris data from the satellites must be transmitted continuously for 40 seconds without interruption to the GPS receiver for normal operation.

By uploading pre-calculated almanac and ephemeris data in proprietary "EPO (Extended Prediction Orbit)" data format to the GPS module, the waiting time for the initial data transmission from the satellites is now significantly shortened. The EPO data contains predicted ephemeris data for 7/14/30 days and need to be re-downloaded once it expires.

What are NTP servers?

NTP servers provide your mobile with a very accurate time reference that help ensure a fast GPS lock.

As standard most Mediatek phones use a Chinese server for this and so a connection from anywhere else in the world is likely to be very slow. With this app you can set the NTP servers to ones that are closer to your own location.

How this app works:

*The application can download the files on-demand or on a daily, weekly or monthly schedule.

*Download is done from a more stable location for the EPO files than the FTP location that Mediatek previously used.

*The files are downloaded to a temporary location in the application folder and then moved to /data/misc

*To automate downloads, select your required frequency, switch the toggle to "ON" and save.

*An unobtrusive flash message will display briefly "EPO Updated" when the files have been updated at the scheduled time.

What One-Click does:

*Backs up your original config files.

*Updates your EPO files.

*Deletes your mtkgps.dat file for regeneration.

*Updates your gps.conf file with NTP time servers appropriate for your region.

*Injects a line into your build.prop which puts the Dalvik VM in a mode which enhances the accuracy of the GPS.

Added monthly and weekly scheduling of download.

Disabled monitor service when scheduling is not used.

Added gps.conf time server tweaks.

Feature requests welcome.

是什么让这个程序有什么不同？目前，这是将自动为您下载在后台调度的EPO文件的唯一应用程序。

使用此应用程序需要您自担风险！我建议在使用前进行完全备份。

此应用程序可以自动下载每天，每周或每月的EPO的文件，如果你想这样做，而不需要任何的互动。

它具有一键功能（OK这是2点击：D），使您能够快速得到一些优化设置您在您所在地区的设备。

你原来gps.conf和build.prop文件的备份都是用自动恢复。

要求：

*使用EPO文件联发科设备

*最小Android版本的冰淇淋三明治

* Root权限（理想情况下与SuperSU，可能会与他人合作）

*互联网接入

什么是EPO文件？

启用AGPS GPS模块可以启动速度更快，执行速度更快TTFF（首次定位时间），并获得在弱信号环境中更快地定位信息。

平均而言，使用AGPS切GPS模块“冷启动”时间的一半，与“热启动”下调至一秒。

当GPS接收器上电的第一次，从卫星历书和星历数据，必须连续进行40秒钟，而不会中断进行正常操作的全球定位系统接收器传送。

通过上载在专有的“促红细胞生成素（扩展预测轨道）”的数据格式，以GPS模块预先计算历书和星历数据，等待时间，用于从卫星的初始数据传输现在显著缩短。欧洲专利局的数据中包含的预测星历数据，30年7月14日天，需要重新下载一次，到期。

什么是NTP服务器？

NTP服务器提供你的手机有一个非常准确的时间参考，帮助确保快速GPS锁定。

作为标准的联发科大部分手机使用中国服务器这一点，所以从其他地方在世界上的连接可能会非常缓慢。有了这个程序，你可以设置NTP服务器那些更接近自己的位置。

如何应用程序的工作原理：

*该应用程序可以下载点播或每天，每周或每月的日程中的文件。

*下载是由更稳定的位置的EPO文件比联发科先前使用的FTP位置完成。

*文件被下载到应用程序文件夹中的临时位置，然后转移到/数据/杂项

*要自动下载，选择您需要的频率，开关切换到“ON”和保存。

*将显示一个不显眼的闪光消息短暂“EPO更新”时，这些文件已被更新在预定的时间。

什么一键的作用：

*备份你原来的配置文件。

*更新您的EPO文件。

*删除再生的mtkgps.dat文件。

*更新与NTP时间服务器适用于您所在地区的gps.conf文件。

*注入一个线到build.prop这使Dalvik虚拟机的模式这增强了全球定位系统的准确度。

下载添加每月和每周调度。

当不使用禁用调度监控服务。

添加gps.conf时间服务器调整。

功能要求的欢迎。</div> <div class="show-more-end">
