Product Brief

Product Description

The SE868K5-RTK offers a compact design and optimized positioning engine for high-quality navigation. Its real-time kinematic (RTK) capabilities deliver exceptional performance for applications that require high precision (e.g., precision agriculture and drones).

This module uses two frequencies (i.e., L1/E1 and L5/E5) to enhance location accuracy and reduce multipath effects in urban areas. With the injection of differential corrections, the SE868K5-RTK can achieve centimeter-level accuracy in addition to its standard capabilities.

Form Factor Family

The SE868 sub-compact form factor (11 x 11 mm) is a well-established industry standard in a 32-pad, QFN-like package. Modules in the family vary in depth dimension from 2.6 to 6.1 mm, depending on the presence and type of integrated antenna.
