Quectel Releases New Dual-Band GNSS Module LC79D

Quectel Wireless Solutions, a global supplier of cellular and GNSS positioning modules, announced that it has launched a compact dual-band GNSS module LC79D with support of L1 and L5 bands for satellites designed to greatly improve positioning accuracy. LC79D was recently showcased at MWC Shanghai 2019, June 26-28.

Featuring concurrent multi-constellation GNSS receivers on dual GNSS bands, the new module can work on L1 and L5 bands for GPS, Galileo and QZSS satellites; the L1 band for GLONASS and BeiDou satellites,  as well as the L5 band for NavIC, formerly known as the IRNSS satellite. Compared with the GNSS modules working on L1 band only, LC79D can generally increase the number of visible satellites, significantly improving positioning drifting when driving in rough urban canyons and enhance positioning accuracy, according to the company.

Embedded with LNA and multi-tone active interference, the module owns higher sensitivity and reliable anti-jamming capability, ensuring exceptional acquisition and tracking performance even in weak signal areas. Multiple communication interfaces including UART and SPI are said to simplify customer designs and accelerate time-to-market for customers’ products at reduced costs. With a small dimension of 10.1mm×9.7mm×2.4mm, it fully meets requirements of size sensitive applications. Compact design, low power consumption and high performance make it optimal for vehicle, people and asset tracking as well as sharing economy applications.

“The launch of LC79D shows Quectel’s global leading position to provide positioning modules for applications requiring higher accuracy and reliability, especially in rough environments with weak signals,” said Wang Min, automotive and GNSS product director at Quectel. “LC79D gives customers high-level integration and flexibility to realize precise positioning in real time.”

Quectel products have been widely applied in IoT/M2M fields including smart payment, telematics and transport, smart energy, smart city, security, wireless gateway, industry, healthcare, agriculture and environment monitoring.
