Furthermore, the module operates by default in the L1 band and incorporates compatibility with the modern BeiDou B1C signal, improving location accuracy and stability.
Thanks to its compact 9.7 x 10.1 x 2.5 mm LCC form factor and its architecture based on the low-power Airoha AG3352 chipset, the SL871K2 is ideal for devices with space constraints and low power requirements. The module integrates a low-noise amplifier (LNA) and a post-amplification SAW filter, increasing receive sensitivity and improving performance in challenging signal conditions. It also supports both active and passive antennas and offers multiple power options, facilitating migration from 1.8 V or 3.3 V designs.
Among its most notable features is the high-precision 1PPS synchronization output, with a jitter of just a few nanoseconds, especially useful in time-critical applications. This is complemented by advanced synchronization and monitoring capabilities such as TRAIM (Time Receiver Autonomous Integrity Monitoring), self-survey mode, and satellite maintenance functions—features particularly valuable in cellular base stations, telecommunications infrastructure, and industrial synchronization systems.
The SL871K2 also supports A-GNSS technologies in both standalone and server-assisted modes, significantly reducing signal acquisition time and improving cold-start performance. Its UART and I²C interfaces allow for easy integration with various embedded platforms and electronic systems. Furthermore, the module is RED certified and RoHS compliant, ensuring compatibility with European regulations and sustainability standards.
Because of all these features, the SL871K2 is geared towards applications such as fleet management, GNSS-assisted smart tolling, automotive navigation, telematics, asset tracking, sports devices and industrial IoT systems that require precise positioning and reliable synchronization.
