What is Telematics?
Telematics is the technology that connects vehicles to the cloud—making it possible to collect, transmit, and analyze data from trucks, trailers, and other fleet assets in real time. In the freight industry, telematics powers everything from GPS tracking and engine diagnostics to driver safety monitoring and compliance reporting.
The Bottom Line: Telematics is the digital nervous system behind modern fleet operations, turning vehicles into connected data sources.
Why Telematics Matters
If you operate or integrate with commercial fleets, telematics data is essential for building intelligent logistics solutions:
Without telematics, you’re flying blind. With it, you can automate operations, improve safety, reduce costs, and build smarter products on top of live fleet data.
How Telematics Works
Data Collection
Commercial vehicles are equipped with telematics devices—often Electronic Logging Devices (ELDs)—plugged directly into the vehicle’s diagnostic port. These devices continuously collect data like speed, engine status, GPS location, and driver behavior.
Data Transmission
The collected data is transmitted in real time to a Telematics Service Provider (TSP) such as Samsara, Geotab, Motive, or Verizon Connect via cellular networks.
Telematics Data You Can Access
Through the Catena API, you can retrieve comprehensive telematics data from connected fleets:
Vehicle Data
- Real-time GPS location and speed
- Odometer readings and engine hours
- Fuel levels and consumption
- VIN, make, model, and year
- Diagnostic trouble codes (DTCs)
Driver Data
- Driver identification and assignments
- Hours of Service (HOS) records
- Duty status and availability
- Drive time and violations
- Co-driver information
Trip Data
- Trip start and end locations
- Route tracking and mileage
- State-by-state distance (IFTA)
- Idle time and stops
Fuel Transactions
- Purchase location and timestamp
- Gallons purchased and cost
- Reconciliation with location data
- Fraud detection signals
The Telematics Integration Challenge
Building integrations with telematics providers is complex and resource-intensive:
Common Integration Challenges:
- Each TSP has unique APIs, data formats, and authentication methods
- Maintaining individual integrations requires significant engineering resources
- Data quality and availability varies widely across providers
- Rate limits and API changes require constant monitoring
- Normalizing disparate data schemas is time-consuming and error-prone
Catena solves this by providing a single, unified API that handles all provider integrations, data normalization, and ongoing maintenance—so you can focus on building your product instead of managing integrations.
Catena currently supports 288 ELD providers. See the list.
