The XT21 is a cost-effective GPS tracker designed for remote asset telematics and is fully ALTAGAMA GPS compatible for seamless fleet management and asset monitoring. Built around an integrated GPS engine and LTE cellular connectivity, XT21 delivers dependable real-time tracking and basic telemetry for trailers, portable equipment, and other high-value remote assets where power may be intermittent or minimal.
With two all-purpose digital inputs and one internal analog input to monitor battery voltage, the XT21 provides the essential signals ALTAGAMA GPS needs to detect events, log asset status, and trigger alerts. Its compact, low-power design makes the XT21 an ideal GPS tracker for organizations that need reliable location data, anti-theft alerts, and remote asset health monitoring without complex installation.
Key Highlights
- ALTAGAMA GPS compatible out of the box: plug telemetry into your existing ALTAGAMA GPS dashboard for instant visibility and reporting.
- Real-time tracking over LTE: consistent, low-latency position updates for remote assets where cellular coverage is available.
- Low-power design for intermittent power environments—suitable for trailers, portable equipment, and field assets.
- Two all-purpose digital inputs for event detection (door open, motion, keyed ignition, tamper alerts when wired).
- Internal analog input for direct battery voltage monitoring—track asset power state and receive low-voltage alerts.
- Cost-effective telematics solution focused on essential location and telemetry data without unnecessary complexity.
- Compact form factor tailored to asset installations where space and power are limited.
How It Works with ALTAGAMA GPS
The XT21 sends GPS position and telemetry over LTE to ALTAGAMA GPS, where the device data is unified with other fleet and asset sources. ALTAGAMA GPS ingests the XT21’s location, digital input events, and battery voltage readings to provide live maps, historical playback, alerts, and telematics reports that support operational decisions and anti-theft workflows.
- Real-time location and telemetry updates: position fixes are transmitted via LTE to ALTAGAMA GPS for live monitoring and historical logs.
- Event detection via digital inputs: wire the two all-purpose inputs to sense door open/close, auxiliary alarms, keyed ignition, or simple motion sensors; ALTAGAMA GPS maps these inputs to events and notifications.
- Battery voltage monitoring: the internal analog input continuously reports battery voltage so ALTAGAMA GPS can generate low-battery alerts and uptime analytics.
- Alerting and rules: ALTAGAMA GPS can trigger geofence alerts, inactivity warnings, or tamper notices based on XT21 inputs and location data.
- Integrate with other telematics feeds: combine XT21 location and telemetry with fuel monitoring, BLE sensor streams, or other device data in ALTAGAMA GPS for richer insights.

Why Choose This Tracker with ALTAGAMA GPS
The XT21 offers a practical balance of capability, cost-effectiveness, and straightforward integration with ALTAGAMA GPS. For organizations focused on fleet management, anti-theft protection, or basic telemetry from distributed assets, XT21 supplies the critical data ALTAGAMA GPS needs—real-time location, digital event signals, and battery-voltage telemetry—without excess complexity. This reduces installation time, lowers ongoing costs, and lets operations teams scale monitoring across many remote assets.
Paired with ALTAGAMA GPS’s reporting, geofencing, and alerting, the XT21 becomes a reliable building block in a broader telematics strategy. Whether you need continuous real-time tracking for critical loads, scheduled checks for parked trailers, or low-power monitoring for rarely used equipment, the XT21 provides focused GPS tracking and telemetry that simplify asset management and enhance security.
