Gosuncn RichLink GD303 LTE Cat.1 OBD Device Now Available!
August 11, 2025 – Gosuncn RichLink has officially launched its latest LTE Cat.1 high-performance OBD device, the GD303! With its outstanding performance, rich functionality, broad application adaptability, and ease of use, the GD303 expands Gosuncn RichLink’s OBD tracker product family and addresses more core needs in digital Fleet Management.
Reliable LTE Cat.1 Connectivity
The GD303 supports LTE Cat.1 cellular technology with 2G fallback, delivering stable and efficient network connections for vehicles worldwide, particularly in regions such as Latin America and the Asia-Pacific. As global operators phase out 2G/3G networks, LTE Cat.1/Cat.1 bis has already captured 50% of global IoT connections and continues to grow rapidly. According to leading consulting firm TSR, by 2030, 76% of aftermarket in-vehicle connections will adopt LTE Cat.1/Cat.1 bis technology, exceeding 35 million connections.
High Performance, Automotive-Grade Quality
Equipped with a high-performance, independent high-precision positioning chip, the GD303 supports GPS, GLONASS, Galileo, and BeiDou for multi-system positioning, offering stronger anti-blocking capability and improved accuracy. Its built-in six-axis sensor enables driver behavior analysis, collision detection, and basic fault alarms, providing valuable data for UBI insurance, fleet management, and more. Powered by a high-performance MCU and automotive-grade components, the device ensures stability and data processing capability under complex operating conditions.
Enhanced Compatibility for More Use Cases
The GD303 supports software-based automatic switching across four CAN channels and is compatible with mainstream vehicle CAN protocols. It meets advanced data acquisition needs such as OEM data reading, fault diagnostics, mileage, fuel level, and seatbelt status. With BLE 5.3 connectivity, it can integrate with external accessories such as wireless sensors (tire pressure, temperature/humidity, Bluetooth tags, etc.), greatly improving data collection flexibility.
The device features an ultra-low-power deep sleep mode with static consumption below 600μA, conserving energy effectively. Its built-in backup battery enables immediate abnormal event reporting when the vehicle loses power or the device is removed, ensuring data security at all times.
Thanks to its robust performance and compatibility, the GD303 is suitable for a wide range of applications, including UBI insurance, shared mobility, and fleet management. In fleet management, it helps operators monitor vehicle status, improve operational efficiency, and reduce fuel and maintenance costs. In shared mobility, it enables precise vehicle status and location tracking. For UBI insurance, driving behavior analysis data provides a solid basis for policy pricing.
Quick Deployment, Secure and Reliable
The GD303 uses a standard OBD-II Type B interface, making it ideal for quick deployment in ride-hailing vehicles, private cars, and commercial fleets—truly plug-and-play with no wiring required. For maintenance, it supports FOTA (firmware over-the-air) updates and OTA parameter configuration, simplifying operations and reducing costs while keeping the device in optimal condition.
Built on Gosuncn RichLink’s self-developed new-generation embedded software architecture, the GD303 supports modular integration for rapid cloud platform connectivity, enabling efficient deployment.
In terms of data security—one of users’ top concerns—the GD303 excels with encrypted data transmission and secure boot mechanisms, providing a robust defense for sensitive information.
The Gosuncn RichLink GD303 LTE Cat.1 High-Performance OBD Device is designed to be the preferred solution in the aftermarket connected vehicle space, offering high performance, fast integration, and easy deployment to meet the core requirements of customers at all levels in digital fleet management, while continuously creating value for users worldwide.
