Advanced Soldier Monitoring and Tracking System Using GPS and GSM Introduction The infantry soldier of tomorrow promises to be one of the most technologically advanced modern warfare has ever seen. Around the world, various research programs. The challenge was to integrate the piecemeal components into a lightweight package that could achieve the desired result without being too bulky and cumbersome or requiring too much power. Communicating with the base station become the fundamental challenges in military operations also the proper navigation between soldier s organizations plays important role for careful planning and co-ordination. So this paper focus on tracking the location of soldier from GPS, which is useful for control room station to know the exact location of soldier and accordingly they will guide them Also High-speed, short soldier wireless communications to relay information on situational awareness, such as Biosensors, GPS navigation, Wireless communication.

Block diagram explanation: Power supply unit: This section needs 2 voltages +12 and +5 Volts, as a working voltages Hence specially designed power supply is constructed to get regulated power supply. Measurement of Respiration & Temperature: Thermistor is used for the measurement of body temperature and respiratory temperature. This Thermister is a passive transducer and its resistance depends on the heat being applied on it. We have arranged the sensor in the potential divider circuit. This sensor exhibits a large change in resistance with a change in body temperature. The respiratory rate is determined by holding the sensor near the nose. The temperature sensor part is attached to the patient whose temperature has to be measured, which changes the values and thus the corresponding change in the temperature is displayed on the monitor graphically. Also all temperature measurements are updated in the patient s database. Here in our project we use bead temperature sensor. Monostable Multivibrators Monostable Multivibrators have only ONE stable state (hence their name: Mono ), and produce a single output pulse when it is triggered externally. Monostable Multivibrators only return back to their first original and stable state after a period of time determined by the time constant of the RC coupled circuit. GPS: We use GPS technology to give accidental information about the vehicle. When traffic accidents occur, the system immediately notifies the location of accident to emergency personnel like ambulance by use of GPS technology
ARM 7: The heart of the system is microcontroller which will access the data. In our project ARM7 is used. The ARM7 which we used for our project is LPC2148 (PHILLIPS) ARM7 is high-performance, low-cost, low power consumption RISC processor. For a variety of areas, such as embedded control, multimedia, DSP and mobile applications, ARM architecture is the first RISC microprocessor designed for low-budget market. The embedded operating system will be subject to certain restrictions. But because of its low price, reliability and other factors, it is widely used in various industrial controllers. Buffer: Buffers do not affect the logical state of a digital signal (i.e. a logic 1 input results in a logic 1 output whereas logic 0 input results in a logic 0 output). Buffers are normally used to provide extra current drive at the output but can also be used to regularize the logic present at an interface. Driver: This section is used to drive the relay where the output is complement of input which is applied to the drive but current will be amplified. Relay: It is an electromagnetic device which is used to drive the load connected across the relay and the o/p of relay can be connected to controller or load for further processing. GSM (Global System for Mobile Communications) GSM (Global System for Mobile Communications, originally Groupe Spécial Mobile), is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by mobile phones. It is the default global standard for mobile communications with over 90% market share, and is available in over 219 countries and territories.
The GSM standard was developed as a replacement for first generation (1G) analog cellular networks, and originally described a digital, circuit-switched network optimized for full duplex voice telephony. This was expanded over time to include data communications, first by circuit-switched transport, then packet data transport via GPRS (General Packet Radio Services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS). Methodology: A robust accurate positioning system with seamless indoor and outdoor coverage is highly needed tool for increasing safety in emergency response and military operation. GPS-based positioning methods mainly used to field rescue. The position and orientation of the rescuer and the trapped is acquired using GPS chip. Using the GPS data of both the units the relative distance, height and orientation between them are calculated from the geometric relationships based on a series of formulas in Geographic Information Science (GIS). Using this technology, we are doing the navigation between two soldiers. The data will be sending wirelessly by RF Transceiver. This device can do accurate coordination via wireless communication, helping soldier for situational awareness. GPS module have serial interface. Receiver information is broadcast via this interface in a special data format. This format standardized by the National Marine Electronics Association (NMEA). Applications: 1. Privacy of telecommunications 2. Home location register 3. Surveillance 4. Military Advantages & Disadvantages: Advantages: 1. We can monitor the health in real- time 2. A sensor network based health monitoring system that is dependable and safe.
3. Automated and continuous monitoring of patients can be reveal problems at an early stage leading to better control. 4. Utilizing medical facilities if only condition very serious. 5. The system has high performance, high reliability and low power consumption. Disadvantages: 1. The temperature dependent and the dynamic characteristics change with different levels of ambient light and temperature level.
