• GSM is the second digital mobile communication system, and at present it is the mobile communication system that has the largest coverage and owns the most number of users. This time. No matter where you are, you can monitor the position and situation of your own car at any time through the GSM communication system

           By receiving detection messages, this product can detect where your car is at the present moment and report to you the present situation of your car including whether it has been broken into or towed. Through the delicate microphone of the SIMTEX, you can monitor the present situation of your car from a faraway place. You can use the telephone remote control function to set follow-up message report modes which will report the situation of your car to you periodically. By telephone voice or software setting, you can conveniently adjust the systematic functions of the SIMTEX. If any emergency happens, you can press the SOS button to ask for help, immediately make "SOS Alert" calls, or "SOS Alert" short messages, to your family member of friends. You can also turn on the conversation function to talk with them. The stand-by battery will provide power when the power source is abnormal (low voltage or damaged by external force).

 

GPS - Know Your Exact Position Anywhere In The World

GPS [global positioning system] is a worldwide radio-navigation system formed from the constellation of 24 satellites and their ground stations. It is a system mainly used to locate the user’s position at a time. Although GPS was originally intended for military applications, but now it is mainly used in marine, location-based services and terrestrial navigation. GPS can work for 24 hours in any type of weather condition, irrespective of sun and rain. Working of GPS system GPS works in a wonderful way. The GPS satellite circles the earth twice a day in a precise orbit and transmits signal information to earth. GPS receivers take into this information and use “triangulation method” to calculate the user’s exact location. The meaning of “triangulation” is receiving radio signals from a distance. Along with knowing the distance, you also need to know exactly the position of the satellites in space. This is done with the help of high orbits and carefully monitoring the instruments for locating the satellites. Finally you also need to correct any type of delays that the signal can experience as it has to travel for a long distance through the atmosphere.

Importance of GPS system GPS is important as it helps you to figure out where you are and where you are going when you are traveling from one place to another. Navigation and positioning are important but cumbersome activities, which GPS makes it easier. Once GPS locates your position, then it starts tracing other factors like speed, bearing, tracks, trip distance, sunrise/sunset time, distance to destination and several other details. GPS uses “man-made” stars as reference points to calculate positions accurate to a matter of meters. However, with recent forms of GPS you can make measurements much better than centimeter readings. So it is with the aid of GPS that you can give a unique and specified address to every square meter on the planet. You can get GPS services without any subscription fees and set up charges. So these days GPS finds its way into cars, planes, boats, construction equipments, farm machinery, laptop computers and movie making gears.

Modern GPS systems With the world advancing rapidly everyday, there are recently discovered Newer GPS receivers with WAAS [Wide Area Augmentation System] that can improve the quality and accuracy of location of any one at any time. Although no additional equipment is required, yet users get the advantage of Differential GPS [DGPS] to get correct signals within the distance of three to five meters. So use GPS systems to get the maximum benefits of modern technology.
