Car trackers use satellite positioning systems to determine vehicle location. They transmit this data through cellular networks.

These devices record detailed trip information and store historical data for later analysis.

GPS and GLONASS Technology

Car trackers rely on satellite networks to pinpoint vehicle locations accurately. GPS uses signals from at least four satellites to calculate coordinates.

Many trackers also use GLONASS, Russia's satellite navigation system. This dual-system approach improves accuracy, especially where GPS coverage is weak.

The tracker's receiver processes signals from several satellites. Each satellite sends timing and orbital data, and the device calculates distance based on signal travel time.

Signal accuracy factors:

  • Number of visible satellites
  • Atmospheric conditions
  • Physical obstructions
  • Antenna quality

Tall buildings in cities can block satellite signals. GLONASS compatibility helps maintain tracking accuracy by providing more satellite options.

Real-Time Tracking Explained

Real-time tracking gives location updates within seconds of vehicle movement. The GPS tracker captures position data and sends it through cellular networks to monitoring platforms.

Data is sent at set intervals, usually every 10-60 seconds. Some trackers change the update frequency based on speed or movement.

The tracker uses a cellular modem to connect to mobile networks. 4G LTE connectivity ensures reliable data transmission where there is cell coverage.

Users access live location data through smartphone apps or web platforms. These show current position, speed, direction, and movement status on maps.

Emergency situations can trigger instant alerts. Rapid acceleration, impacts, or unauthorized movement send immediate notifications to contacts.

Trip History and Data Storage

Car trackers keep records of vehicle activity over time. Trip history includes departure times, destinations, routes, speeds, and total distance.

Most devices store data locally for 30-90 days before overwriting old information. Cloud-based systems can keep historical data longer if you subscribe.

Typical stored data includes:

  • Start and end locations
  • Route paths and stops
  • Maximum and average speeds
  • Engine on/off times
  • Idle duration

Fleet managers and parents use trip history to analyze driving patterns. Insurance companies may offer discounts based on driving data.

The tracker's memory determines storage limits. Regular syncing with cloud servers backs up information and prevents data loss if the device is damaged or removed.

Types of Trackers in Cars
