Insert the SIM card in the slot of the GSM module. When SW1 is pressed, GSM calls the mobile number already entered in the program code, and the buzzer sounds. The buzzer sound is to alert nearby people. Once the call is established, GPS gets latitude, longitude, and altitude coordinates and thus collects the exact location of the caller. In this project, we are going to understand how a GPS module works, and we will get acquainted with one of the popular GPS receiver module called NEO 6M, this module differs in size from the one used in mobile phones but the working is same. By using the information provided by the GPS receiver module and the Thingspeak IoT platform, we will Circuit diagram of the GPS- and GSM-based vehicle tracking system is shown in Fig. 2. It is built around Arduino Uno board (BOARD1), 16×2 LCD (LCD1), GPS module, GSM module and a potmeter (VR1). Working of the circuit is very simple. To operate the circuit, you need to follow the steps given below: Fig. 2: Circuit diagram of GPS- and GSM-based GPRS is a 2.5G system based on GSM [3]. GSM and SMS (Short Message Service) technology are used for vehicle tracking in [4]- [5] which requires another GSM or cellular phone connected to a PC or In this tutorial we learn How to GPS Module Interfacing with NodeMCU ESP8266. NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term “NodeMCU” by default refers to the firmware rather than the development kits. RTK is short for real time kinematics. A GPS receiver capable of RTK takes in the normal signals from the Global Navigation Satellite Systems along with a correction stream to achieve 1cm positional accuracy. GNSS includes satellites from GPS (USA), GLONASS (Russia), Beidou (China), and Galileo (Europe). On top of these signals an RTK receiver FIGURE 1: As previously mentioned, the M2M Board is built around two controller modules, the LEON-G200 and the NEO-6Q, which are available from u-blox AG. The LEON-G200 is a Quad Band GSM/GPRS data and voice module. Communications to the module are through AT commands. The UART module on the PIC32 device handles the AT commands. The cell phone operating system downloads the GPS almanac data (satellite ephemeris and status information) over the internet via the cell network and loads it into the GPS module much faster than the it would take to download that from the GPS satellites directly at 50 bps (yes, that's 50 bits per second, GPS is rather old tech optimized for The M66’s ultra-compact profile makes it particularly suited to size-sensitive applications, and the module can serve a range of applications such as wearable devices, automotive, PDAs, asset tracking, POS, smart metering and telematics. Size: 17.7mm × 15.8mm × 2.3mm. Communication Interface: UART/USB. LnLWq6.
