Navtelekom - SMART S-2421

The SMART S-2421 is a compact GLONASS/GPS vehicle tracker designed for dependable telematics and Green-Gps compatible deployments. Combining integrated GNSS and GSM antennas with a built-in rechargeable battery and hardened power protection, the S-2421 delivers continuous real-time tracking and robust telemetry for fleet management, anti-theft monitoring, and remote diagnostics.

Designed to integrate with platforms such as Green-Gps, the SMART S-2421 provides the essential inputs, outputs, and sensor connectivity that modern GPS tracker installations require. With Bluetooth 4.0, a 1-Wire interface and configurable I/O lines, this device supports flexible vehicle telemetry — from ignition detection and immobilizer control to fuel monitoring when paired with the appropriate sensors.

Key Highlights

• Green-Gps compatible GPS tracker for reliable real-time tracking and centralized fleet management.
• Integrated GLONASS/GPS and GSM antennas for simpler installation and consistent signal reception.
• Built-in 380 mAh rechargeable battery ensures operation through short power outages and supports anti-theft alerts.
• Robust automotive-grade power line protection rated up to 200 V to withstand transient voltages.
• Bluetooth 4.0 and 1-Wire interface enable connection to external sensors and BLE modules for expanded telemetry (temperature, fuel sensors, beacons).
• Three universal inputs and two configurable outputs provide flexible ignition detection and immobilizer or accessory control.
• Compatible with local and remote configuration tools (NTC Configurator and DRC remote device management) for firmware management and centralized administration.

How It Works with Green-Gps

When integrated with Green-Gps, the SMART S-2421 streams location and vehicle telemetry to the platform so operators can view real-time positions, create alerts, and generate reports. Green-Gps reads GNSS fixes, cellular signal and power status, and the device’s input/output events to build actionable fleet insights. The S-2421’s sensor interfaces (1-Wire and Bluetooth) expand telemetry capabilities, enabling Green-Gps to ingest additional data points from external modules.

• Real-time location and telemetry updates (GNSS position, time, and movement).
• Configurable event reporting for inputs and outputs — use inputs for ignition detection and outputs for immobilizer or remote control.
• Support for 1-Wire sensors and Bluetooth sensors so Green-Gps can display temperature, door/movement, or fuel-sensor readings when those sensors are attached.
• Device health telemetry including battery backup status and power-line event reporting for proactive maintenance.
• Support for remote firmware updates and centralized management via manufacturer tools, enabling coordinated device maintenance alongside Green-Gps fleet workflows.

Technical Overview

Use Cases

• Fleet management: real-time tracking, route monitoring, and basic telemetry reporting for midsize vehicle fleets.
• Anti-theft and immobilization: detect unauthorized movement and use configurable outputs to trigger immobilizer circuits or warnings.
• Remote diagnostics and maintenance: monitor device health and power events to reduce downtime and schedule maintenance.
• Sensor-enabled telemetry: attach 1-Wire or Bluetooth sensors to monitor fuel level, temperature, or cargo conditions and feed data into Green-Gps dashboards.

Why Choose This Tracker with Green-Gps

The SMART S-2421 balances reliability and flexibility for Green-Gps compatible deployments. Its integrated GNSS/GSM antennas simplify installation while the internal battery and robust power protection increase uptime and resilience in vehicle environments. For operators focused on fleet management and anti-theft protection, the S-2421 supplies the core telemetry, configurable I/O and sensor connectivity needed to capture ignition events, control immobilizers, and extend telemetry through Bluetooth sensors or 1-Wire devices.

Beyond hardware, the device’s compatibility with NTC Configurator and the DRC remote device management system lets teams standardize configuration and deploy firmware updates at scale — an important complement to Green-Gps’s real-time tracking, reporting and alerting capabilities. If you need a compact, Green-Gps compatible GPS tracker that supports vehicle telemetry, anti-theft workflows, and external sensors, the SMART S-2421 is a practical choice backed by manufacturer documentation and centralized management tools.
