Quectel LC99T is a dual-band high-precision timing GNSS module, which can concurrently track GPS, GLONASS, Galileo, BDS, QZSS and NavIC satellite signals. It also supports SBAS (including WAAS, EGNOS, MSAS and GAGAN) and AGNSS functionality. In contrast to single-band GNSS modules, it tracks a substantially greater number of visible satellites, enhancing overall signal reception. With nanosecond timing accuracy, the module is particularly well suited for infrastructure applications with precise timing requirements. LC99T is designed to meet the most stringent timing synchronization requirements within global 4G/5G mobile networks. In addition, the module can generate a 10 MHz square wave for various applications.

By effectively minimizing timing errors of the primary source of cellular network synchronization, it empowers operators to maximize their network performance. Simultaneously, LC99T meets the strict synchronization demands of the next-generation networks across various vertical industries such as 5G X-Haul, smart grid, data centers, satellite communications, calibration services, and industrial automation applications. The module’s multi-band capability reduces timing errors to less than 13.6 ns under open-sky conditions. Additionally, it is designed and manufactured in accordance with the stringent Quality Management System, aligning with the IATF 16949:2016 Standard.
