N2 Palm GNSS Receiver
The N2 Palm is a slim and lightweight GNSS RTK receiver featuring 1,590 channels and support for multiple global satellite constellations. Its compact 48 mm-thick body and approximately 670–720 g weight make it convenient for all-day field surveying.
It supports Static, Fast Static, PPK and RTK surveying, while its integrated IMU provides tilt surveying up to 60° with approximately 2.5 cm accuracy, allowing surveyors to measure points without keeping the pole perfectly vertical.
