GPS control for personal use (Conclusion)
In the final part of the article, I will talk about the ViaLatM system and announce the new ViaLatM Lighthouse and Tracker application for Android smartphones.

System development has been underway since August 2014.
The system has Russian and English interfaces.
The system can be used for personal monitoring and monitoring of small car parks.
The system works great on tablets and smartphones even with low resolution screens.
The system supports various personal trackers, telematics devices, applications and protocols.
The only limitation of the free version is that the story is stored for 12 months .

The system has a developed reporting system. Reports can be obtained in the form of graphs and charts. Reports can be created directly in the application window, or in external files. In preferences, the user sets the format of reports generated in external files. Currently available formats are: HTML, RTF, PDF, OpenDocument Text Document, OpenDocument Spreadsheet, MS Excel MS Word 2007, MS Excel 2007, MS PowerPoint 2007, CSV.
A simple and convenient android application for GPS monitoring. Well integrated with ViaLatM service. With it, you can let relatives and friends know where you are right now, keep your family, friends and colleagues informed about the time you arrive at your scheduled meetings. Allows you to save and analyze the history of walks and travels.

To let loved ones know where you are right now, just start the “Beacon”, create a link and send it to the recipients. By default, the location fix mode is set every 15 minutes (this allows you to economically use the battery life of the smartphone). By following the link on the Internet, loved ones will know your current location.
If you want to let your family or friends know about the time of your arrival at the meeting, uncheck “Use only WiFi” in the tracker settings (wifi is usually not available on the way), create a link and send it to the recipients. Launch Tracker. Information about your movement will be transmitted to the server every 5 minutes and available to the recipients - they will know whether you are delayed, or arrive on time.
If you want to save the history of your walk or trip, check the “Use only WiFi” checkbox in the tracker settings (to save mobile Internet traffic). Launch Tracker. After the walk, stop the tracker. Information about your track will be transmitted and available when a WiFi connection is established on the smartphone.
The main tasks in developing the service and application were simplicity and ease of use. The service and applications for it will be actively developed and improved, but these tasks will always be the most important.

Useful features of the system
- Cartography: OpenStreetMap, Yandex People’s, Yandex Satellite, Yandex Traffic, Google Satellite, Google Roads, Bing Roads, MapQuest, OpenCycleMap.
- Geofences: a polygon (a convenient opportunity is to quickly delete the last created point), a rectangle, a circle.
- You can monitor multiple devices at the same time.
- The composition of the information fields that are displayed in a pop-up window (when you click on the tracker icon) can be configured.
- It is possible to quickly (through the tracker icon) go to its information panel.
- Within your account, you can create additional users who can monitor and generate reports, but cannot change information and device settings.
- For any selected tracker, you can create observers (they can only monitor the device). Access for observers can be limited in time. At any time, it can be discontinued.
