GNSS modules

GNSS modules connect IoT devices to the Global Navigation Satellite System – a widely deployed and accepted way to determine location precisely without needing to rely on coverage by or the signal strength of cellular networks. It therefore underpins navigation, tracking and tracing of a wide variety of goods and assets and billions of GNSS IoT devices are now deployed worldwide.

However, GNSS applications are not one-size-fits-all and there are some challenges for organizations to find and adapt the right solutions. Where automotive solutions lack a clear view of satellites for instance, caused by dense buildings or bad weather, it can be very challenging for any GNSS module to provide an accurate position – which is compounded by multipath effects prevalent in deep urban canyons. Here, innovations such as dead reckoning can help, which can use information from sensors such as the accelerometer to augment the performance of GNSS positioning. Innovators need to know which approach works best for them – and that is where we can help.

Quectel’s wide range of ultra-compact, low-power GNSS modules cover the full range of requirements in standard precision, high precision, dead reckoning and timing. We can therefore support application scenarios as diverse as ADAS and self-driving to smart agriculture and micromobility. And, with unsurpassed aftermarket support services, the journey with us does not end with a purchase – that’s just the beginning.

To help our customers test their GNSS products, we provide access free of charge to our QGNSS evaluation tool software. QGNSS is compatible with all Quectel GNSS modules and enables real-time display and logging of all GNSS satellite and signal data. It also offers integrated AGNSS, NTRIP and firmware upgrade functions for RTK evaluation and supports NMEA, RTCM and Quectel proprietary streams.
