Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small dimensions are due to the use, for the first time, of a GSM/GPRS module integrating the GPS receiver. […]

We remake the old device with the cheaper SimCom module SIM900. In the previous post we present the GSM section and now we can present the complete localizator. Introduction This system allows for localization without directly using GPS technology; we are able to […]

Well, here is some news for you: by using cellular network data and properly querying Google, even a simple GSM module is able to determine one’s position, with a fairly acceptable error margin. Although […]

Before doing this, however, we need to know which cell the remote GSM device is connected to, that is, we need information regarding MCC, MNC, LAC, and CID. To […]

Once the two-sided board is ready, be sure you have a very fine-pointed welder of up to 20 watts and a 0.02-inch-diametered (possibly, even smaller) welding thread. First of all, take care of the microcontroller; solder […]
