GlobalSat - GTR-388C1

The GTR-388C1 from a rugged device family is a compact, Green-Gps compatible GPS tracker engineered for eBikes, motorcycles and small vehicles. Built around 4G LTE (Cat 1) connectivity with automatic fallback to 3G and 2G, the GTR-388C1 delivers reliable real-time tracking and telemetry to the Green-Gps platform, packaged in an IPX7 waterproof enclosure designed for exposed outdoor installations.

With a high-sensitivity GNSS receiver (A-GPS), integrated antennas, an 820 mAh rechargeable backup battery, and firmware updates over-the-air, the GTR-388C1 is optimized for fleet management, anti-theft protection and compact vehicle deployments where concealed mounting, robust sealing and efficient power management matter.

Key Highlights

• Green-Gps compatible for real-time tracking and fleet management via TCP/UDP/HTTP or SMS.
• 4G LTE (Cat 1) with automatic fallback to dual-band UMTS/HSDPA (3G) and dual-band GSM (2G) for wide area coverage.
• High-sensitivity GNSS with A-GPS for fast position fixes and accurate route replay.
• IPX7 waterproof enclosure with waterproof cable connector and thermal solution for exposed vehicle installations.
• Built-in 820 mAh rechargeable backup battery to maintain operation on power loss and support anti-theft scenarios.
• Rich I/O: ACC detection (ignition), multiple digital inputs (including emergency button), one analog input, and a digital output for relay control.
• Lightweight, compact form factor (~66.5 g) with accessory options for flexible mounting and integration.

How It Works with Green-Gps

When installed and configured, the GTR-388C1 streams GNSS location and vehicle telemetry to Green-Gps using standard protocols. Green-Gps ingests position updates and I/O events for live dashboards, geofencing alerts, route replay and scheduled reports—turning device-level signals into actionable fleet intelligence.

• Real-time location and telemetry updates routed to Green-Gps via TCP, UDP, HTTP or SMS.
• Ignition (ACC) detection reports allow Green-Gps to correlate driving time, idling and ignition events for driver and vehicle reporting.
• Motion detection by the built-in G-sensor supports movement alerts and tamper/theft detection workflows.
• Analog input can be integrated for telemetry such as fuel-level sensor readings when connected and calibrated through Green-Gps.
• Digital output can drive an external relay (optional accessory) to implement remote relay control or immobilizer workflows under Green-Gps control.

Technical Overview

Use Cases

• Motorcycle and eBike anti-theft protection with movement alerts, backup battery persistence and remote relay control via Green-Gps-managed workflows.
• Compact fleet management for small vehicles and last-mile delivery with real-time tracking, route replay and ignition-based duty reporting.
• Route replay and monitoring for safety and compliance—store and transmit GNSS fixes to Green-Gps for historical analysis.
• Vehicle diagnostics and telemetry integration when used with optional accessories (relay, OBDII cable) to extend Green-Gps telemetry data.
• Concealed asset tracking for rental fleets and shared micromobility where waterproofing and compact mounting are required.

Why Choose This Tracker with Green-Gps

The GTR-388C1 pairs rugged hardware and focused connectivity with the Green-Gps platform to deliver reliable real-time tracking and actionable telemetry for small vehicles and two-wheel fleets. Its IPX7-rated enclosure and thermal design make it suitable for exposed installations, while the built-in backup battery and efficient power management ensure continuity during power interruptions—critical for effective anti-theft and fleet monitoring. With versatile I/O (ACC detection, emergency input, analog telemetry and relay output) and support for FOTA, the device simplifies installation, maintenance and scalable fleet rollouts on Green-Gps.

Green-Gps's ecosystem also supports additional sensor types and platform features, so fleet managers can combine the GTR-388C1's wired telemetry (ignition, analog fuel sensors, relay-based immobilization) with Green-Gps dashboards and alerts. The result is a compact, dependable GPS tracker that integrates into broader asset management, telemetry and anti-theft strategies without unnecessary complexity.
