The KT-520M is a rugged GPS tracker designed for long-term, low-maintenance deployment and is Green-Gps compatible for seamless integration into your tracking and fleet workflows. Combining LTE‑M cellular connectivity with Kineis satellite fallback, the KT-520M delivers reliable location reporting and telemetry for vehicles and mobile assets that move between urban coverage and remote areas. Its maintenance‑free SAFT 17Ah battery and power‑efficient firmware make it an ideal choice for installations where long battery life and uninterrupted tracking matter.
The KT-520M pairs native GNSS positioning and a 3‑axis accelerometer with BLE for local configuration and OTA firmware updates, allowing fast setup and lifecycle management through Green-Gps. Use Green-Gps to view location history, motion/tamper events, battery state, and to combine KT-520M telemetry with additional vehicle data sources for advanced fleet management, anti-theft workflows, and operational reporting.
Key Highlights
- Green-Gps compatible: Integrates location and telemetry into Green-Gps dashboards and alerts for centralized fleet management.
- Dual-mode connectivity: LTE‑M primary with Kineis satellite fallback keeps assets visible across mixed-coverage areas.
- Long-life, maintenance-free power: SAFT 17Ah non-rechargeable battery with an estimated ~5 years life at 20 messages/day.
- Accurate GNSS positioning plus motion detection from a built-in 3‑axis accelerometer for tamper and movement events.
- Local setup and OTA: BLE enables configurable periodic reporting and firmware updates locally; LTE‑M supports remote OTA.
- Rugged environmental rating: IP69K ingress protection and wide operating temperature range for demanding vehicle and asset use.
- Compact, lightweight form factor suited for covert or permanent vehicle and equipment installations.
How It Works with Green-Gps
When integrated with Green-Gps, the KT-520M supplies GNSS coordinates, motion/tamper events, and battery state so you can monitor assets in near-real-time where cellular connectivity exists, and maintain continuity via satellite when it does not. Green-Gps ingests the device’s telemetry to trigger alerts, build reports, and correlate location data with other operational signals in your fleet or asset-management workflow.
- Real-time location and GNSS telemetry updates (near‑real-time on LTE‑M; periodic updates on satellite fallback).
- Motion and tamper events from the built‑in 3‑axis accelerometer for anti-theft and movement detection.
- Battery level and power-state reporting so Green-Gps can notify on declining energy and plan maintenance.
- Automatic satellite fallback: KT-520M sends location via the Kineis network when LTE‑M coverage is unavailable, preserving historical traces and alerts.
- BLE for local configuration and OTA; LTE‑M remote firmware updates for fleet-scale device management.
- When paired in Green-Gps with vehicle telemetry or third‑party sensors, you can correlate KT-520M location with ignition, fuel monitoring, or immobilizer events managed by other integrated systems.

Use Cases
- Fleet management for mixed-coverage routes — maintain consistent tracking and history as vehicles move between city LTE‑M and remote regions with satellite fallback.
- Anti-theft monitoring — use accelerometer-triggered alerts in Green-Gps to detect unauthorized movement or tampering and respond quickly.
- Long-term asset deployment — ideal for equipment or trailers that require multi-year, low-maintenance tracking without battery swaps.
- Remote equipment tracking — assets operating off-grid or in areas with intermittent cellular service remain visible through Kineis satellite messages.
- Telemetry aggregation — combine KT-520M GNSS and motion data with Green-Gps-managed vehicle telemetry (fuel, ignition, immobilizer signals) supplied by other integrated systems.
Why Choose This Tracker with Green-Gps
The KT-520M is built for reliability and minimal upkeep: long-life battery chemistry, a rugged IP69K enclosure, and dual-mode connectivity reduce downtime and site visits. Using the KT-520M with Green-Gps gives fleet managers and operations teams a single pane for GPS tracker data, motion and tamper events, and battery health metrics. Green-Gps’s alerting and reporting tools make it straightforward to create anti-theft workflows, map asset movement, and synthesize GNSS telemetry with other vehicle data sources such as fuel monitoring, ignition state, or immobilizer events when those signals are available through integrated systems. For organizations that need durable, Green-Gps compatible tracking with satellite fallback, the KT-520M offers a practical balance of longevity, ruggedness, and connectivity continuity.
