TopNTP

TopNTP is an application designed to enhance GPS performance on Android devices. This tool is particularly beneficial for users who rely on accurate location data and want to optimize their GPS settings. TopNTP provides features that include the installation of a customized gps.conf file, which is essential for managing GPS configurations effectively.

The app allows users to choose from various profiles, with a recommendation to utilize the default Google profile. This flexibility empowers users to tailor the GPS settings according to their specific needs and preferences. Customization options enable adjustments to the chosen profile, ensuring that users can achieve the best possible GPS performance based on their requirements.

One of the significant aspects of TopNTP is its provision of aGPS almanacs, specifically maintained for devices utilizing Qualcomm or similar chipsets. The almanac data is updated every 30 minutes and is delivered through a content delivery system. This feature is particularly valuable for users who require up-to-date satellite information to enhance their GPS accuracy and speed.

Additionally, TopNTP includes a dedicated NTP server pool maintained by Derek Gordon. While there is a common misconception that the closest server is always the best option, the app promotes Derek Gordon's server as the preferred choice due to its superior data quality and frequent updates. Users can benefit from this optimized server configuration to improve their GPS functionality.

The app incorporates a system for donations to support the maintenance of the server. Contributions made through the app are divided between Derek Gordon and Zatta, both of whom are active members of the XDA developer community. This funding model allows users to contribute to the app’s development while enjoying enhanced features and reduced waiting times for installing patches.

TopNTP operates on a star rating system to manage waiting times for patch installations. Users who donate can earn stars, where each star reduces the waiting time before a patch can be applied. For instance, users without stars must wait 20 seconds, while those with three stars or who have become premium users can install immediately. Becoming a premium user is available at a cost, offering a discount compared to the highest star rating.

For ASUS users, TopNTP is designed to work efficiently with specific files, such as the gpsconfig.xml file typically found in the /system/etc/gps directory. The application modifies this file and makes a backup during its first run, which is crucial for restoring settings if needed. It's important for users to retain this backup, as it is only created during the initial setup or when the app is updated.

Users need to be aware that the app requires root access and is compatible with Android 4 and above. Changes in Android operating systems, particularly from version 4.4 onwards, have affected the ability of the app to mount the /system partition in read-write mode for some devices. This limitation necessitates manual adjustments before installing the custom gps.conf file, which can be inconvenient for some users.

TopNTP also addresses ROM updates, as the patches applied by the app are located on the /system partition. This means that users will need to reapply the patch after updating their ROM. However, for those utilizing Cyanogenmod-based ROMs with addon.d support, a script will be placed in the addon.d directory to preserve the patch during updates. Users have the option to disable this feature in the app's settings if they choose.

The app's user interface is designed to be straightforward and user-friendly, allowing users to navigate through its features without difficulty. The ability to choose and customize profiles adds a layer of functionality that enhances user experience while ensuring that GPS settings can be optimized according to individual preferences.

For anyone looking to enhance their GPS capabilities, downloading TopNTP can provide significant advantages. The combination of aGPS almanacs, a dedicated NTP server, and customizable GPS settings contributes to a more reliable and accurate GPS performance on Android devices. With its focus on user support through donations and an active community, TopNTP stands out as a valuable tool for Android users who require precise location data.
