Design of Travel Assistance System Based on LBSand SNS

Based on Beidou satellite navigation system and LBS related technologies,a travel assistance system was designed to share personal location and dynamic information around among net friends through mobile phone map and online communication,to make up for the poor interactivity and weak support on team activities of existing GPS- based satellite navigation software. This paper begins with requirements analysis,then proposes the system design and implementation technology,and concludes with the system's strength analysis and application outlook.
