GPS Tracking

GPS Coordinate Collection

• FleetTrack uses the GPS sensor of students' smartphones.
• Students travelling on a bus can share their current location.
• The mobile application periodically reads the device's latitude and longitude.
• Each location update contains information such as:
• Latitude
• Longitude
• Timestamp
• Device/user identifier
• Multiple students on the same bus can provide location data.

GPS Data Transmission

• The mobile application sends GPS coordinates to the FleetTrack backend.
• Location data can be transmitted using HTTP or WebSocket.
• The backend receives and validates the location data.
• The server processes location updates from multiple devices.
• The most reliable location data is selected or aggregated for the bus.

GPS Location Display

• The processed bus coordinates are sent to connected students using WebSocket.
• The frontend receives the latest coordinates in real time.
• The bus position is displayed as a marker on an interactive map.
• The marker is updated whenever a new location is received. Students can view the bus's current location and its movement along the route.
