Abstract [eng] |
Many different positioning systems for ordinary IT users were developed since GPS technology became available not only to US military. Those systems led to new kind of services – location-based services. Some of the widely used positioning systems are analyzed in this work and their main functionality is marked out, positioning technologies compared. Architecture of multi-user positioning system and its main implementations aspects are given. Also there is an analysis of distributed system development and testing issues that may lead to project failure or its cost rising and a software development and testing model suggested. This is a practical model which lets reduce the risk of failure. |
