Introduction
| The K827N GNSS board is capable of tracking all current and planned GNSS constellations, supporting both L-Band and S-Band signals. Featuring unique Dual-Resolving RTK technology, it delivers centimeter-accuracy positioning and high-precision heading in both static and dynamic environments. Its standard dimensions of 46mm × 71mm × 10mm make it easy to integrate into various systems. This board is ideal for applications such as land surveying, autonomous driving, precision agriculture, machine control, robotics, and UAVs. |
