Development of a GPS-enabled localization device

There exists a dichotomy in the design of modem electronic systems: the simultaneous need to be low power and high performance. This arises largely from their usage in battery-operated portable (wearable) platforms. Accordingly, the goal of low-power design for battery-powered electronics is to extend the battery service life while meeting performance requirements. Designers of portable embedded systems therefore focus on power management methods to increased system performance while reducing operating power consumption. Static and dynamic power management policies, memory management schemes, bus encoding techniques, and hardware design tools are needed to meet these often-conflicting design requirements. The present work was motivated by the need for a low-power device that can be used as an anti-theft alarm system for high-end bikes. The implemented system is a highly low-power object tracking system using GPS and GPRS technologies. The system calculates the position coordinates using GPS technology and sends them to a server through GSM technology. The system can also intelligently detect any motion on the bike and report suspicious activities on the bike. The system operates on very low power and is capable of remaining functional for weeks on a regular battery. The system can switch to an ultra-low power mode in order to extend the battery life for months. This thesis discusses hardware and software techniques for power management system to design a low-power portable embedded system. Also, the designed power management system for this application is described. In the final chapter, development of the proposed device and implementation of the designed power management methods are defined.
