There are many types of operating systems for GSM GPS Tracker . Some have more features than others. Some may be simple embedded systems while others are sophisticated operating systems such as Microsoft’s CE 5.0. Let us start with a discussion of a unique Russian GPS device and then proceed to talk about the file systems and operating system on it. The Glonass GPS Navigator Explay GN-510 is a device that is available to Americans through online auction sites such as eBay. The battery life is reported to be about 3.5 h. Many GPS devices in the United States such as the Garmin Nuvi 1300 have a battery life of 4 h. The device comes with a battery, has a charger, and can be powered through a USB cable.

The operating system is the interface between the human and the GPS device. It is a program that runs on the device and provides a layer of abstraction so the user can operate the hardware easily by pointing and clicking with a graphical user interface. The operating system frees the user from learning about complex hardware codes and dealing with the Personal GPS Homing Device at the microprocessor level. The customized version of the CE 5.0 system allows the user to navigate a series of screens to collect or give information to the GPS device. One of the screens gives the user a map and tells which Glonass and GPS satellites are accessible at that location and then gives a longitude and latitude. It also gives the time, date, real-time speed, average speed, and altitude. The interaction can be done by touch screen for simple options such as clear all. The operating system for this device is broken up into six large areas such as video, music, ebooks and photo, system, navigation, and GPS information.

Since there are videos, photos, ebooks, and documents, just about any type of digital 
evidence could exist on this device. One has to understand what the device is capable of using or storing before one can fully investigate it. The operating system can use a variety of file formats that include AsF, AVI, WMV, MP3, WAV, JPEG, BMP, PNG, and TXT. This is not surprising since this device uses Windows CE 5.0 which is found on many American mobile devices. Some GPS devices sold in America such as the Tom Tom XL support approximately 56 languages and 35 different voices with both male and female voices. The Glonass GPS Navigator Explay GN-510 operating system is reported to operate in three different languages. 

There have been devices available on eBay for some time that allow a person to track the location of another elderly person, dog, car, or valuable object. One device is called “Real-Time Spy Mini GSM GPRS Vehicle GPS Tracking Device.” This type of device needs a cell phone SIM and then one sends it a text message to activate it. The person with the receiver can connect to a PC and see on a map where the device is at any time and where it has been. This type of device can help to locate a person with Alzheimer’s disease who may have wandered from home. However, it may be used by a possessive person who is stalking a lover and an investigation of a computer or GPS device may be needed if there is a complaint.
