This SinoGNSS N2 kit pairs a compact palm-sized GNSS receiver with a built-in UHF radio and GSM modem plus a field controller, giving surveyors both base and rover functionality in one package. The receiver uses ComNav's K8 module to track all major GNSS constellations, communicates over UHF at ranges up to about 15 km, and is rated IP67 for dust and water resistance. A 10,000 mAh battery provides roughly 20 hours of continuous field operation, with pole-tilt compensation up to 60 degrees for accurate tilted-pole measurements.
