Project objectivesCreate a real-time bus tracking system capable of:
1.Friendly website with database which can update real-time location.
2.A self-powered user station with stable performance.
3.Long distance wireless communication with the radius about 1mile.
4.Compact stable on-bus tracking system with high accuracy(error less than 10m)

Goals
Low•Self-Made Portable GPS device with LCD demonstrating the
location.•Project Website and dynamic database.•Long distance RF communication with specific designed antenna.•Prototype of Wooden user station (maybe holding laptop)
Med •On-camps single bus tracking•Display the location directly to the user station.
High •Whole route multi bus real-time tracking.•Update real-time information to the website
supported by dynamic database.
