Abstract :
The design of an experimental AGPS-based (Assisted Global Positioning System) elderly tracking system is described. The system includes: a wearable AGPS terminal with HSPA two-way communication capability and designed for 10 days of continuous battery operation, a GPS assistance data server with reference GPS stations, location database and server, application server, and Web server and client. Assistance data is retrieved by the wearable AGPS terminal using the SUPL protocol (secured user plane location). This paper describes the design of each component based on key considerations such as accuracy, availability, battery life-time, and user behavior.
