Quectel Wireless Systems has introduced new technologies aimed at enhancing the accuracy, reliability, and security of its high-precision Global Navigation Satellite System (GNSS) modules, as competition intensifies in the global positioning market.
The Chinese Internet of Things (IoT) solutions provider announced that its LG290P, LG580P, and LG680P modules will support two additional technologies: RTKHOLD, developed in-house, and the Galileo Open Service Navigation Message Authentication (OSNMA) and High Accuracy Service (HAS), both part of the European Union’s Galileo satellite system.
RTKHOLD is designed to maintain centimetre-level positioning accuracy even when correction signals are briefly interrupted. The system models how GNSS errors evolve over time, allowing devices to predict corrections and sustain precision for up to ten minutes without a live data feed. Quectel said this would be particularly beneficial in sectors such as precision agriculture and rural automation, where connectivity dropouts are frequent.
“RTKHOLD ensures that temporary link losses no longer render high-precision applications unusable,” said Windy Fang, Director of GNSS Product Line at Quectel Wireless Systems.
In parallel, Quectel said its modules will adopt Galileo HAS in the fourth quarter of 2025. The free service delivers decimetre-level positioning accuracy directly from satellites, without the need for constant connectivity, a feature expected to appeal to sectors such as transport, rail, and smart agriculture.
The company has also rolled out Galileo OSNMA support for its LC29H module. The authentication service, which became operational in July 2025, uses digital signatures to verify that navigation messages originate from genuine Galileo satellites, protecting against spoofing and other forms of signal manipulation.
Customers can activate OSNMA support through a firmware update, enabling secure and authenticated positioning for applications such as autonomous vehicles, fleet management, and critical infrastructure.
Quectel is showcasing the new technologies at Intergeo 2025 in Frankfurt.
Headquartered in Shanghai, Quectel employs more than 5,800 staff globally and provides a full suite of IoT hardware and services, spanning cellular, satellite, and short-range wireless connectivity.
