The SE868K5-RTK is a multifrequency and multiconstellation positioning receiver module.

• Centimeter-Level Accuracy: Incorporates Real-Time Kinematics (RTK) capabilities, achieving horizontal positional accuracy of less than 1 meter without RTK and approximately 1 centimeter with RTK corrections. 

• Multi-Constellation and Multi-Frequency Support: Simultaneously tracks multiple satellite systems—GPS/QZSS (L1, L5), Galileo (E1, E5), GLONASS (L1), and BeiDou (B1, B2)—across dual frequency bands (L1/E1 and L5/E5), enhancing positioning accuracy and reducing multipath effects. 

• Compact Form Factor: Measures 11 x 11 x 2.8 mm, facilitating integration into space-constrained applications and ensuring compatibility within the scalable xE868 family. 

• High Sensitivity: Offers acquisition sensitivity of -146 dBm and tracking/navigation sensitivity of -165 dBm, ensuring reliable performance even in weak signal conditions.

• Low Power Consumption: Optimized for energy efficiency, with power consumption of approximately 70 mW during acquisition and tracking at 1 Hz, making it suitable for battery-powered devices. 

• Assisted GNSS (A-GNSS): Supports self-generated predictions and ephemeris file injection, expediting Time to First Fix (TTFF) and enhancing performance. 

• Satellite-Based Augmentation System (SBAS): Compatible with EGNOS, WAAS, GAGAN, and MSAS, providing augmented positional accuracy and integrity. 

• Raw Measurement Output: Provides raw data in RTCM format, enabling high-accuracy applications and facilitating Real-Time Kinematics (RTK) support. 

• Embedded Components: Includes an integrated Low Noise Amplifier (LNA) and Surface Acoustic Wave (SAW) filter, ensuring optimal performance and coexistence with other radio systems.
