Low Power Wearable Device with GPS and Indoor Positioning System

Abstract

Until today, positioning system plays an important role in our daily life. As our technology advances, there are many technologies depending on Positioning System. Positioning System not only improving the navigation system that we used on road, but also support games, application, advertisement and so on. Global positioning system, or GPS in short is one of the commonly used positioning systems around the world. However, GPS alone isn't sufficient to carry out positioning system. The aim of this project is to build a low power consumption global positioning system with indoor positioning system. The first part of this project is to build a global positioning system with low power consumption. The GPS module will be powered by a rechargeable battery. Therefore, it is very important to use a low power consumption microcontroller and module to ensure the duration of usage is enough. Second part is to build an indoor positioning system. In order to maintain low power consumption characteristic, only gyroscope sensor and some other low power consumption module to calculate distance traveled, by using approximate calculation, position of the user will be estimated.
