Quectel Wireless Solutions has launched a compact dual-band GNSS module, the LC79D, that supports the L1 and L5 bands from navigation satellites to improve positioning accuracy.
Featuring concurrent multi-constellation GNSS receivers on dual GNSS bands, LC79D uses L1 and L5 bands for GPS, Galileo and QZSS satellites, L1 band for GLONASS and BeiDou satellites, and L5 band for IRNSS satellites.
Compared to GNSS modules that use the L1 band only, LC79D can generally increase the number of visible satellites, significantly improve positioning drifting when driving in rough urban canyons and enhance positioning accuracy.
Embedded with a low-noise amplifier (LNA) and multi-tone active interference, the module provides 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 simplify customer designs and accelerate time-to-market for customers’ products at reduced costs.
With dimensions of 10.1 × 9.7 ×2.4 millimeters, the tiny LC79D meets the requirements of size-sensitive applications. Compact design, low power consumption and high performance make it suitable 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.”
The LC79D module was showcased at MWC Shanghai 2019 during June 26-28.
