XM982-K4 RTK Module

XM982-K4 is a high‑performance, multi‑constellation RTK GNSS module built on the NebulasIV platform. It delivers reliable centimeter‑level positioning accuracy (0.8 cm + 1 ppm) by tracking all major satellite systems (BDS, GPS, GLONASS, Galileo). With dual‑antenna heading support, an industrial operating temperature range, and a compact form factor, it is engineered as the core positioning solution for autonomous drones, robotics, precision agriculture, and advanced surveying equipment.
