K501 GNSS Receiver
Compact Universal RTK System with Full Constellation Tracking and Long Endurance
The K501 is a new-generation GNSS receiver designed for professional surveying, mapping, and engineering projects. With a compact magnesium-alloy structure, the K501 integrates a 1408-channel full-constellation module, high-precision RTK and PPK positioning, and tilt survey support. Its lightweight yet rugged design, combined with IP67 protection and IK08 shock resistance, makes it reliable for long-term outdoor operations.
Equipped with a large-capacity 7000mAh battery, the K501 delivers up to 40 hours of continuous fieldwork in rover CORS mode, significantly reducing downtime. The receiver supports Bluetooth, Wi-Fi, and 4G connectivity for seamless data transfer and real-time corrections.
With multi-constellation, multi-frequency tracking and tilt survey capability (<2 cm accuracy within 60°), the K501 ensures consistent precision in challenging field conditions. Whether for topographic surveys, cadastral mapping, or infrastructure construction, the K501 offers a stable, high-performance GNSS solution in a lightweight form factor.
