# What is Telematics?

> Understanding the technology that connects commercial vehicles to the cloud and powers modern fleet operations

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:

    Monitor vehicle locations and movement patterns across your entire fleet.
  </Card>

  <Card icon="clock" title="HOS Compliance">
    Track driver Hours of Service to ensure regulatory compliance and prevent violations.
  </Card>

  <Card icon="gauge-high" title="Vehicle Diagnostics">
    Access engine data, fuel levels, odometer readings, and vehicle health metrics.

  </Card>
</CardGroup>

<Info>
  **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

<Steps>
  <Step title="Data Collection" icon="microchip">
    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.
  </Step>

  <Step title="Data Transmission" icon="signal">
    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.
  </Step>

  <Step title="Data Aggregation" icon="database">
    Catena normalizes and aggregates data from the TSPs, transforming disparate formats into a unified, clean dataset accessible through a single API.
  </Step>

  <Step title="Integration" icon="code">
    Your application connects to Catena's API to access standardized telematics data without building and maintaining dozens of individual TSP integrations.
  </Step>
</Steps>

## Telematics Data You Can Access

Through the Catena API, you can retrieve comprehensive telematics data from connected fleets:

<AccordionGroup>
  <Accordion title="Vehicle Data" icon="truck">
    * Real-time GPS location and speed
    * Odometer readings and engine hours
    * Fuel levels and consumption
    * VIN, make, model, and year
    * Diagnostic trouble codes (DTCs)
  </Accordion>

  <Accordion title="Driver Data" icon="id-card">
    * Driver identification and assignments
    * Hours of Service (HOS) records
    * Duty status and availability
    * Drive time and violations
    * Co-driver information
  </Accordion>

  <Accordion title="Trip Data" icon="route">
    * Trip start and end locations
    * Route tracking and mileage
    * State-by-state distance (IFTA)
    * Idle time and stops
  </Accordion>

  <Accordion title="Fuel Transactions" icon="gas-pump">
    * Purchase location and timestamp
    * Gallons purchased and cost
    * Reconciliation with location data
    * Fraud detection signals
  </Accordion>
</AccordionGroup>

## The Telematics Integration Challenge

Building integrations with telematics providers is complex and resource-intensive:

<Warning>
  **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
</Warning>

**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.
