GreatWill specializes in GPS tracker wholesale and maintains regular stock of market-proven devices. We support OEM, ODM, and customization services for fleet operators, distributors, and resellers.

GTB9 uses a standard 16-pin OBD-II connector and is designed for vehicles with a compatible OBD-II diagnostic port. For imported vehicles and new-energy vehicles, confirm the port type and electrical compatibility for the specific model before deployment.

In open, unobstructed environments, GPS/BeiDou positioning error is within 10 meters. In blind spots such as underground parking or mountainous areas, the device can record data and upload the missing trajectory after the network or positioning signal is restored.

TCP is a connection-oriented protocol designed for reliable transmission. Compared with connectionless protocols such as UDP, it prioritizes delivery integrity and is well suited to positioning data and alarm information that require stable, dependable communication.
