Project objectives
Create 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)
